Connecting the hob to the mains. Self-connection of an electric hob

We will send the material to you by e-mail

As a rule, when buying a separate electric stove, the process of connecting it is quite simple: for this you just need to plug the plug into the outlet. However, many people only buy work surface- a cooking panel that has many advantages. Connecting the panel to the mains is somewhat more complicated. A dedicated line is required to maintain the hob warranty. In this article, you will learn how to properly connect the hob to the mains.

hob

Before the connection process, you must preparatory work, among which: studying the passport data of household appliances, preparing all the necessary tools, choosing a place for installation. To properly install, you first need to know its dimensions. You can do this by opening the device manual. In most cases, there are also detailed diagrams for connecting wires. It is important to pay attention to the minimum allowable indents from the edge of the countertop, which are also indicated in the instructions. They are recommended to be done a little more, due to the fact that narrow edges can be damaged over time.

Using an electric jigsaw with a fine-toothed nail file, carefully cut lines from one hole to another. In this case, the jigsaw must be pressed firmly. The resulting sawdust can be collected.

To connect an induction hob, use one of the following diagrams:

• Single phase circuit. To find the phase, it is recommended to use a probe or tester;
• Two phase connection. Used in new buildings, but quite rarely.
• Three-phase connection, which is used to increase the power and CCD of equipment.

Connecting the hob to a single-phase power supply

To do this, you must use a network cable that will be designed for the power of the panel. Basically, cables with a cross section of 4 or 6 mm2 are used. A cable with a cross section of 6 mm2 is more reliable and is well suited for powerful panels. Usually, cables with four wires are used.

On the diagram you can see the following symbols:

• L1, L2;

This marking is generally accepted throughout Europe, it is enough to simply establish what to connect where. To connect two phases, a special jumper is included in the kit. It must be inserted between the phase contacts. To connect a four-wire cable to a three-pin access point, twist the black and brown wire s and connect them with phase wire networks. The use of adapters or extension cords is prohibited.

The following connections must be made in the mounting box:

• Connect the brown and blue flowers. If there is a marking on the case, the brown wire must be connected to the “L” terminal, and the blue one to the “N” terminal;
• Connect the yellow-green wire to the central terminal.

Connection to a three-phase network

In networks whose voltage is 380 V, a five-core wire is mainly used. In this case, to connect, you need to remove the jumpers from the three contacts of the terminal box.

After that, connect three phase wires to them. Thanks to the use of this scheme, it is possible to rationally distribute the mains voltage.

Another connection option is to plug into a power outlet. It is necessary to determine the phase and zero connectors with the indicator, and then attach the wires to the necessary terminals.

To make a connection, it is enough to understand the most simple principles electricity.

Choice of fixtures

The power of almost all surface models is between 5 and 7 kW. When installing more powerful panels, it is necessary to use sockets for the hob with a current of 32 A. As for the cable, then with a current of 16 A, you need to use a copper cable with a cross section of 2.5 mm2, with a current of 32 A - 6 mm2. To facilitate the selection of the required cable section, you can use the following table:

In addition, the connection can be made in the terminal box. This method is more reliable, but to turn off the hob, it is necessary to turn it off with a knife switch on the RCD or machine.

Not all owners know how to connect the hob to the mains, so they often leave this matter to specialists. Connecting really requires certain knowledge and skills. It is about what are the nuances and what you should pay attention to, we will talk in our article.

The socket and plug are made of special plastic, some models may have a cover. Install the socket at a distance of about 90 cm from the floor, to the left or right of the surface.

Often, manufacturers of household appliances do not include a socket and plug in the package, so they have to be purchased separately. To do this, you need to determine which type of connection the hob belongs to. This and other information on how to connect the hob to the socket is indicated in the instruction manual.

The power line for connecting the panel must be brought out separately, and the socket must withstand a current from 32 to 40 A. In those houses where not a gas stove is provided, but an electric stove, power cable released initially. If your home is not of this type, then this wire should be included in the wiring separately.

• Devices up to 3.5 kW can be connected to standard 220 W (load 16 A).
• Power above 3.6 kW requires a 32 A reinforced socket.
• With a 3-phase power supply in the room, a 20 A socket is required for power up to 3.5 kW.

In parallel with the power, grounding is taken into account for additional plug contacts. A single-phase outlet has three, a 3-phase outlet has five. Some manufacturers make kits that include plugs with both three and five pins.

For kitchen panels, special three or four pin sockets are produced. Structurally, they are made so that it is clear how to connect the phase and protective wires.

The plug is selected based on the current - up to 40 A. When connecting the plug to the wires, it is advisable to take into account the polarity. If a wire was included in the configuration, this is good, but if it didn’t turn out to be the one, then they buy a three-core PVA. The cross section of the wire must correspond to the power of the device.

For installation, disassemble the plug body and pass the wire through the hole. The cores are stripped and held under the screw connectors of the plug: phase and zero go to the extreme terminals, and ground to the top. The screws are well tightened, pressing the cores.

Connecting an induction hob in a shield

Mounting the hob is not possible without connecting it through an RCD + automatic device, or a differential automatic device with a leakage current of 30mA. Such additional equipment makes the operation of the panel as safe as possible, increases protection against electrical shock and spontaneous combustion if a current leakage occurs due to damaged insulation. Connection action algorithm induction hob in the shield is not difficult.

• The phase wire (gray or brown) in the shield is connected to the bottom terminal differential automaton. It is usually denoted by the number 2.
• Zero wire ( of blue color) is connected to the terminal marked Latin letter N.
• The ground wire (yellow-green) is thrown to the ground bar.

After the connection in the panel has been made, the hob can be connected to the mains.

Wiring diagrams for induction hob

Self connection The induction hob will not cause difficulties if you follow the instructions in the instructions and follow the safety precautions. There are two types of connection of the hob to the mains: for single-phase and with three phases.

How to connect the hob to a 220 V socket

A single-phase connection is made if a 3-wire wire comes out of the wall. The connection diagram looks like this:

• L1, L2, L3 - phase;
• N(4, 5) - zero;
• PE - grounding.

Connecting the panel to the outlet is done as follows.

1. There is a metal plate on the back of the panel that needs to be unscrewed.
2. Special jumpers are included in the package for the surface, for connecting terminals 1, 2, 3, then the phase is connected (brown, black or white wire).
3. A blue wire is connected to the zero terminals numbered 4 and 5.
4. A yellow-green wire is connected to the protective terminal.
5. After connecting, the plate is put in place, and the screws are tightened tightly.

Before mounting the panel on the countertop, you need to check its performance, as well as the strength of all connections.

How to connect the hob to a 380 socket

In this case, a five-core cable with three phases, ground and zero is used. The installation diagram and process is slightly different from connecting to 220V. Diagram:

• L1, L2, L3 - phase 1, 2, 3 respectively;
• N is zero;
• PE - grounding.

How to connect the hob to a power outlet:

1. Phase 1 (white or black wire) is connected to the first terminal (1), the next one to the second terminal, the last one to the third one.
2. Using a jumper, terminals 4 and 5 are connected, and zero (blue wire) is connected to them.
3. yellow green the wire goes to ground.

Please note that it does not matter at all in what order the wires will be connected, the main thing is to maintain polarity.

How can I connect the hob to the mains without a plug

They resort to connecting a panel without a plug in cases where they do not want to see an unaesthetically protruding outlet in their kitchen. Then the wires from the panel are connected to the wires of the network and hidden in the socket or junction box. You can perform these manipulations using GML sleeves or the KLK-5S junction box.

With plugless connection option junction box should be as close to the panel as possible. If the wires are at the bottom, they are pulled through the wall or cable channels are laid.

Modern models of hobs have universal wired equipment for a 220 V and 380 V network. They have a four-wire cable, and this fact often confuses inexperienced craftsmen, because only three wires peek out from the wall.

To connect the panel to a single-phase network, simply remove it to the side and insulate one phase conductor. It is also possible to connect two phases together using a ferrule.

In panels with a power of 7 kW or more, designed for operation from 380 V, a cable with 5 cores is connected. To connect to 220 V, a black and brown wire, blue and white (gray) are connected in pairs, and the ground remains single.

Sleeve connection

When the hob is connected to the mains without using a plug and socket, GML sleeves are purchased. They have a through design and are used to connect copper cables and wires.

The cross section of the conductors must correspond to the cross section of the sleeve. For example, if the cores of the network wire are 6mm2, then the sleeve must also be 6mm2. It happens that a cable with cores comes out of the wall, the cross section of which is larger than that of the cores from the panel cable. Then the sleeve on the smaller side is sealed with additional core 1.5 mm2 folded in half. After connection, the ends of the sleeves are clamped with press tongs and insulated. Finished construction hide in the socket and close the lid.

The disadvantage of sleeve connections is that the structures are not collapsible. Also, not everyone at home has the appropriate crimping tool, and simple pliers will not help here.

Connection via junction box

Mounting box for connection kitchen panel more convenient for later use. If the wire begins to move away, then it can be easily tightened by simply disassembling the case. Another plus is the compact size compared to the socket. A box without ore is placed in the space behind kitchen drawers or under the tabletop.

Connection in progress in a standard way. If you look inside the junction box, you can see the corresponding markings on the paired connectors.

• Zero from the shield and panel is thrown to the left and right N terminals, respectively.
• In the same way, phases are connected to connectors 1 and 2 for a 220 V network and 1, 2, 3 with a 380 V network.
• Ground is connected to the bottom terminals.

After all manipulations mounting box closes and hides in the place allotted for it.

Common connection errors

If, after connecting to electricity, the hob does not work correctly or spontaneous combustion occurs, then the reasons may lie in the following:

• the operation of only two burners instead of four may be associated with a blockage during single-phase connection of three-phase models;
• connecting a device with a power above 3.5 kW to a conventional socket with a 220 V (16 A) network;
• connection through an automatic machine without RCD;
• use of wire with conductors of smaller cross section for high-power panels;
• ignoring the phase jumper when connected to the terminals.

To avoid unpleasant, and sometimes tragic situations, they carefully study the connection instructions and only after that they take up the terminal block. Consistency in work and compliance with safety regulations will save not only time, but also finances for the subsequent repair of equipment or the purchase of a new one.

Hobs powered by electrical network(induction, with a glass-ceramic surface and spiral) confidently entered everyday life modern man. The popularity of this kitchen equipment due to its versatility, ease of settings and management, modern design and economy. Purchase electrical surface pleasure is not cheap, so many consumers, wanting to save on the services of a master, install the hob with their own hands. The main thing in this process is the observance certain rules, which we will discuss below.

Currently multi-story houses with economy-level apartments are most often rented to the consumer without connection to the main gas network. This option significantly reduces the value of real estate and increases the safety of living. gas stoves in this case are not used. Instead, electric cookers, panels and ovens. This type of equipment is also used on suburban real estate objects located in places where there are no gas pipelines, and the use natural gas in cylinders is difficult and economically inefficient.

Under all the above conditions, installation is carried out in the kitchens of apartments, houses and cottages electrical appliances for cooking, stewing and frying food. There are only two options for equipment for these purposes: you can connect a full-fledged electric stove with an oven to the mains, but most consumers prefer to install hobs and ovens separately. This article is devoted to the installation and connection of any type of hob, both simple with resistance heating elements, and induction panels.

Installing the hob

The installation of the electric hob is carried out in compliance with general requirements regardless of type heating element using a high frequency induction field or heating due to resistance to electric current. According to the external design, these types of appliances are almost indistinguishable, therefore, the same tools and tools are used for their installation in the kitchen. expendable materials. If we talk about electrical panels of any kind, then they will all be built into furniture. Those appliances that are located on the surface of the furniture are called electric stoves without an oven. We will not consider the process of how they are installed.

How to install the hob correctly? This question arises if furniture suppliers have not cut a mounting hole in the countertop. kitchen furniture. If you decide to perform this operation yourself, then you will need the following tools: electric jigsaw, drill, wood drills, ruler and pencil, as well as a screwdriver and pliers. step by step algorithm for the installation of a built-in hob is presented below.

This completes the installation of an induction hob or other type of surface. It is only necessary to check the reliability of fastening the device to the countertop and you can proceed to the next step. We told how to install the hob, now we will describe the process of connecting it to the power supply network. These chapters of the article can be considered as a guide for those who are going to independently connect the electric hob to the power supply. So, let's begin! The next section of our story will be devoted to the connection diagram of the hob.

Scheme of connection to the electrical network of the hob

The power of induction and conventional electric hobs is almost the same for devices with identical technical specifications. Therefore, the scheme for connecting to electricity of any type of hob does not have fundamental differences. AT modern apartments and homes where the electrical wiring is already designed to take into account heavy loads, you just need to install a power outlet connected to the network through a junction box and connect the plug to power wire panels. All! The equipment is ready to go, but there are some nuances!

The fact is that the power cable of an electric hob can have three or four cores, and the internal wiring is always three-core (if it has a ground conductor). In this case, two phase conductors of the power cable of the panel should be twisted together (most often, the insulation of these cores has a black and Brown color). As a result, we will get three cores for connecting the hob to the mains. The picture shows the connection diagram of the power cable of the hob with a power plug for single-phase electrical wiring.

This is how an electric or induction hob is connected at real estate objects, where there is a modern powerful electrical wiring with three conductors: phase, zero and ground. In old houses, apartments and cottages, wiring, most often, does not respond modern requirements both in terms of power and electrical safety. In this case, you will have to install a separate power line to connect the hob, as well as install an additional machine and RCD in the switchboard. The connection diagram for this option is shown in the following figure.

Most models of hobs can be connected to both single-phase and three-phase power supply networks. Unlike three-phase electric motors, there is no need for a phase shift of the sinusoid by 120º to operate the panels. For correct connection devices to any network alternating current it is enough to install or remove special jumpers in the terminal box of the device. Next, we will consider in detail how to connect the hob to the mains.

The process of connecting an electric cooking surface

If the consumer decides to connect a complex and powerful household appliances to the power supply network with his own hands, then he must have elementary knowledge in the field electro installation work. Otherwise, to avoid negative consequences should invite a specialist. Therefore, we will not describe what tools you need to use when connecting an electric hob and provide step by step instructions carrying out installation work. And also we will assume that the power cable with grounding has already been laid to the installation site of the device. So let's get started! Let's start with the installation of the power outlet.

Power outlet

The selection and installation of a power outlet and plug is an essential part of the entire process of connecting powerful household appliances. The plug connection must be capable of withstanding the maximum possible current consumption. The design and other features of the socket and plug do not matter. For a single-phase network, the power outlet and plug have three pins each, and for a three-phase network, five. The following figure shows both types of plug connections for connecting high-power household appliances.

Installation of the power socket and plug is carried out according to general rules carrying out electrical work. The main thing is to observe the polarity of the connection and not mix up the phases with neutral conductors and grounding. If you are unsure which of the conductors is the phase, and which is the zero and ground, you must use indicator screwdriver or multimeter. After installing the power outlet and connecting the hob cable to the plug, it is necessary to perform certain manipulations in the terminal box of the device. This is the subject of the next section of the article.

Connection terminals

At different models hobs, terminal boxes can have a different design, but all of them, in without fail, are equipped with contacts for connecting the following cores of the power cable.

1. Phase terminals for connecting the power supply L1, L2 and L3.
2. Contact for connecting a working neutral conductor N.
3. Connection pin protective earth PE.

As mentioned above, to connect the panels to a single-phase network, it is necessary to install special jumpers on the phase contacts. For a two-phase network, one jumper is installed. Two neutral conductors are bridged for any connection. The figure below shows the installation of jumpers for all types of electrical networks.

Most often, jumpers are included in the delivery of hobs. It is important to install them correctly and not mix up the contacts. Otherwise, a short circuit may occur or the panel simply will not work. The bottom photo shows the most common connection option inside the hob terminal box for single-phase electrical wiring.

Before performing manipulations with the terminals for connecting the device, you should study the instructions for connecting the purchased equipment. On the body of most models of hobs is also presented detailed diagram connections, type of terminals and arrangement of jumpers for different options connections. This will avoid the main mistakes when connecting panels, which we will discuss below.

Typical errors of connecting hobs

Often, after connection, induction and conventional hobs malfunction. Sin for poor-quality installation in this case should not be. Reasons for instability may be installed programs protection from children, moisture on the sensors and many other problems associated with the microprocessor control system and software. Therefore, before using the connected electric hob, carefully study the technical documentation. But there are also common installation errors, which are listed below.

1. Using an ordinary euro-socket that can withstand a current of no more than 16 A. For panels with a power of more than 3.5 kW, this is completely unacceptable.
2. Connection of a powerful device without a differential machine and RCD through a simple circuit breaker with thermal separation of contacts.
3. Connection through a common junction box on objects with old low-power wiring without a ground conductor.
4. Jumper setting error in the panel terminal box, which can lead to a phase connection with zero or ground.

All these mistakes are very dangerous! They can lead not only to the failure of an expensive electric hob, but also to a fire with all the ensuing consequences.

Final part

As you can see, there is nothing complicated in independently connecting the electric hob to the power supply networks. Having minimal knowledge in the field of electrical work and having essential tool, any owner of the device is able to cope with this task. Of course, laying a separate power line for the appliance and installing equipment in a switchboard will require more advanced skills, but in new homes this will not be necessary. In older buildings, it will be necessary to lay a separate line or change the entire internal wiring.

When purchasing built-in household appliances for the kitchen, the question often arises of how to install the hob. Some turn to professional electricians for help, paying a lot of money for the work, while others try to do the work themselves. Connecting the hob to the mains cannot be called difficult, however, there are nuances here. Today we will look at mounting options various types devices and find out what the home master will need to complete this task. And the video instruction will exclude questions if they remain after reading.

Specifications affecting the electrical connection of the hob

When choosing household appliance You need to look at some of the technical specifications. The main parameter here will be the number of phases in home network. And if a single-phase device is connected to three-phase network If it turns out, then the reverse option (a three-phase device to a single-phase network) will not work.

Electrical or gas equipment purchase is a more important issue. If the house or apartment is gasified, then a device powered by electricity will be an unjustified luxury in terms of costs. The cost of electricity is much higher, and the consumption of such a stove will be high. Let's figure out how to connect an electric hob or other type of device yourself.

The nuances of connecting various types of plates

Naturally, the connection of the stove will depend on its type. There are three main ones:

1. electric stoves;
2. induction devices;
3. gas appliances.

Let's start with those that are more common in kitchens - electric ones. After all, electricity is present in any home. Today, a person can no longer imagine life without it. But the "blue fuel" has not yet reached all corners of our vast country.

Connecting an electric stove: pitfalls

Let's start with the fact that this type of device requires mandatory grounding, regardless of the number of connection phases. If desired, installation can be done independently (if the home master has electrical installation skills). Although a beginner can figure out how to connect electric stove, with a deliberate approach and observance of simple rules.

Expert opinion

Engineer-designer of ES, EM, EO (power supply, electrical equipment, interior lighting) ASP North-West LLC

“All work with electrical equipment is carried out only after the voltage is removed from the input shield. Remember that jokes with electricity are dangerous. Electric shock leads to sad consequences, up to death.”

But electric stoves are gradually becoming a thing of the past, giving way to more expensive devices with enhanced functionality and consuming less electricity. We are talking about induction appliances. Therefore, we will consider the question of how to connect the hob to the mains using the example of an induction device.

How to connect an induction hob: rules and necessary tools

The first step is to decide whether the oven for the hob will be mounted. The complexity of the work depends on this. For example, let's take a simpler installation option without it. If a household appliance is being replaced, then if there is a plug and socket in the previous version, everything is simple. But if there is no socket and only a cable is connected to the stove, you will have to tinker. Such work requires the presence of a certain tool:

• knife for stripping insulation and a screwdriver (more often simple than curly);
• cable(the method of its calculation by power will be presented below);
• terminal block to connect the incoming cable to the electrical wire of the device;
• multimeter(or indicator) to check the phase and neutral conductors of the incoming cable.

In order for the respected reader to understand the algorithm of actions, the editors of the site offer detailed step-by-step installation instructions.

Illustration	Action to take
	We will consider the connection of such a device. There is no oven for the hob yet, which allows you to get by with "small forces"
	Under the pedestal on which the device is located, a power wire is connected to the cable coming from the hob
	On the cable of the device that comes with the kit, there is a tag indicating the colors of the connection of the cores. These are phase and neutral conductors, as well as grounding
	The connection is made to the corresponding contact. Wherein neutral wire consists of two cores, which is more reliable
	Similar actions are carried out with a phase wire. Please note that the grounding, consisting of one core, is included in the terminal block between phase and zero. This is due to the wiring rules.
	If you look at incoming veins, you can see that there are two of them, while the one going to the stove is one. The fact is that there is a socket nearby and the second taps are its power supply. If there is no parallel socket, there are no second wires
	Choosing a connecting terminal block, you need to pay attention to the load and the current that it can withstand. If the terminal block is designed for a current of less than 16A, it should be discarded
	Before performing all the described work, it is better to press the ends of the cores with sleeves (they can be with additional insulation)
	Of course, in our case, everything does not look quite aesthetically pleasing. A home master can do more accurately. But the connectivity is top notch.

Important! After a week of operation of the connected hob, tighten the screws on the terminal block again, having previously removed the voltage from the input shield by turning off the machine.

Connecting a gas hob: the nuances of work

Gas appliances are quite simple to install, however, the layman does not have the right to connect them - this requires the help of a specialist from a service company. When connecting such a plate, you can arbitrarily receive an impressive bill and a dismantling order. In this case, you still have to pay for the services of a specialist gas service, but the costs will seriously increase - considerable fines are issued in such cases. And why risk the lives of loved ones in the first place, and even your own?

Hob connection diagrams: we do the work correctly

In order to connect the electrical appliance correctly, you should study various installation schemes, namely:

• single-phase connection diagram;
• three-phase option;
• two-phase connection (the rarest option).

Let's consider each of them separately, starting with the most common.

Installation of a single-phase electrical appliance

This connection is the most common apartment buildings. It is in them that the voltage of 220V is most often found. The diagrams below will help you to carry out the installation yourself.

Three-phase network: connection nuances

Voltage 380 V is often found in private homes. Actually three-phase connection is considered more economical in terms of electricity consumption and allows you to save on bills from energy sales companies.

Connecting the device in two phases

The most rare scheme. It confuses many people. However, not everything is so scary. Two-phase stoves are quite rare and are connected to a three-phase network. In this case, it is only necessary to exclude one of input phases by insulating the core input cable.

Safety precautions for the installation of electrical equipment: requirements and some tips

In the publication, we will consider which wardrobe is better, user reviews, an overview of models and brands, what you need to pay attention to when choosing, useful tips.

Defeat electric shock in the production of installation work is not uncommon, as well as a fatal outcome in this case. However, not only touching live parts is fraught with danger. Incorrect connection, due to which a short circuit occurs, or unstretched contacts in the apartment's electrical circuit are also quite dangerous. The heating that occurs with loose contact causes melting, and then ignition of the electrical wiring. Of course, in this case, automation should serve as protection, but it does not always work. This is especially true for powerful or old machines. Yes, and it is always better to trust yourself. So, when connecting the oven and hob, you should carefully monitor your actions so as not to miss anything. There are no small things in this case.

Let's analyze the main components of the circuit and the rules that should be observed during their installation. Among them:

• plug for connecting the device to the network (if present);
• power socket;
• connections (there may be several varieties);
• the required wire (its cross section).

Plug for the hob: what to consider when buying and installing

If the circuit is mounted using a plug and socket, then you should start by choosing them. The plug is purchased depending on the number of phases and must be able to withstand the power consumption of the hob. It is indicated in the technical documentation for the device. The connection is made in compliance with color coding wires:

• zero– insulation in blue or white with a blue stripe;
• phase– brown, white, black;
• grounding- yellow with a green stripe.

Important! Compliance with color coding helps not only to connect correctly, but also saves in the future when another person undertakes repairs. Simply put, this is what saves lives.

Mounting the power outlet for the oven and hob

Installation of a kitchen power outlet is carried out in a similar way, in compliance with all of the above rules. However, there is one caveat - it must be installed correctly. Do not place the outlet in a place where heat from the stove gets. This error leads to melting of the insulation and a short circuit. It is also worth considering the option of free access to it for the possibility of an emergency shutdown. These simple rules will save you from a fire in the event of a fire. emergency, as well as from herself.

Wire cross section for electric stove and oven: how to determine the required

The cross section of the cable (it is measured in mm2) is no less important during installation than the tight pulling of the contacts. Indeed, in the event of its incorrect choice to the smaller side, the electrical wiring will begin to warm up and, as a result, will not withstand it. The consequences are clear - a fire in case of failure of protective automation. Inexperienced House master he will say that there is no need to take risks - just take a cable with a large cross section. But not everything is so simple. Thick cable for hob:

• difficult to hide or lay on the wall;
• inconvenient to install (the width of the terminal clamps may not be enough);
• its cost will be higher.

We come to the conclusion that exact calculations are needed. They can be produced according to two parameters of the electrical appliance - power consumption and rated current. One formula is indispensable here - the distance from the switchboard and other factors are taken into account. Therefore, we suggest the reader to use online calculators. It's more convenient than figuring it out yourself. desired parameters. All that is required from the user is to enter the required data in the appropriate fields and click the "Calculate" button. In addition, the human factor is excluded, and hence the possibility of errors in the calculations.

Reading time ≈ 3 minutes

You have a need to purchase a hob. After the purchase, it is the connection that becomes one of the problems. First of all, you need to carefully read the manufacturer's instructions if you connect, for example, a Bosch hob or another brand. Connecting the electric hob yourself First of all, you need to start by installing a grounded outlet. In addition, it is necessary to have an adapter clamp and a cable with a cross section of up to 3 mm. Both cable and clip need to be purchased separately.

First, turn the hob over and remove the connector cover. Using a knife, we clean the ends of the cable. After that, it is necessary to determine where the mass, zero and phase are located. To do this, you need to prepare a tester in advance.

The Bosch brand is very popular with consumers. High-quality equipment in terms of connection and operation is simple and straightforward. Everything is thought out here, which is why the installation of equipment and connection does not require much mental stress. The bolts are structurally designed in such a way that they do not require any terminals. Just wrap the bolt in one and a half turns, and then twist it. After carrying out all the manipulations, we twist the contact cover.

That seems to be all regarding the question of how to connect an electric hob. You should also keep in mind that if you buy a connector separately, then it will most likely be made in China. Typically these connectors Bad quality and not properly assembled. Fasteners of such a connector are of poor quality.

Power

When connecting the hob, special attention must be paid to the electrical power. After a short period of time, the stove heats up, which is very convenient. However, you have to pay for everything. Due to the high heating rate, the consumption electrical power large enough. Sometimes it reaches 7 kW. Therefore, higher requirements are placed on the cable. This is especially true for the supply contacts of the hob. In order to minimize contacts and reduce the chance of a short circuit, power can be applied directly to the surface terminals. The main requirement for the cable is copper with a diameter of at least 4 mm.
