Connecting to the mains hob: circuitry for beginners

Recessed cooktops confidently out of the market and our kitchens traditional gas and electric stoves. This is due to the fact that this type of home appliances become more economical, functional, easy to operate and has received a modern design. Hobs can be installed separately from the oven or in a single unit, combine them (top - the gas, and the bottom - an electric and vice versa). Self-installation of such equipment is not a problem, however, there are some nuances. In this article we'll show you how to connect the hob to the mains.

The main technical characteristics affecting the ways to connect home appliances

When selecting cooking surfaces most buyers almost do not pay attention to power requirements. However, this is the most important characteristic, since the installation of modern household appliances, for example, in the homes of old buildings, often have problems with wiring. Therefore, it is better to lay a separate line with a conductor cross-section and a corresponding protective device. Also important in the building phase number (1, 2 or 3) and having a grounding circuit. Cooking surfaces are separated by the type of heating element:

• heating elements;
• induction;
• gas;
• combined (gas and electric hobs).

Nuances connection embedded cookers of various types

Built-in cooking surface, including natural gas, is connected to a separate dedicated power lines to ground and socket withstand current within 32-40 A. The cable used must have three copper conductors with a cross section of at least 4 mm2. In urban apartments are mainly used gas or combined hobs. Induction or TENovye panel usually installed in buildings where there is no possibility to connect gas line.

Important! Regardless of the type of built-cooking surface, while its switching circuit installed must be de-energized!

Electrical connection plate

In the presence of even a minimal knowledge in electrical engineering and compliance with safety independent connection of the hob is not difficult. Before embedding technique, you must first mark the countertop, perform the summarizing a separate electrical ground and only then proceed to the network installation and connection. The manual, which comes complete with appliances, there is a diagram of how to connect the hob to the mains.

How to connect an induction hob

The principle of the connection of the induction hob is virtually identical to mounting conventional electrical model. We offer step by step instructions on how to install this type of kitchen appliances. First you need to prepare all the necessary tools:

1. Tape measure, ruler, set square.
2. electric drill or screwdriver with a drill Æ 10 mm.
3. jigsaws.
4. Mounting syringe with silicone.
5. Cable.
6. Fork.
7. Pliers, side cutters.
8. A set of screwdrivers and wrenches.
9. Knife.

First, mark up the countertop in accordance with the dimensions indicated in the instructions to the hob. Then drilled four holes in the corners, and via cut jigsaw aperture. Edge saw cut well with silicone grease to prevent swelling in the case of moisture.

Let us consider in more detail the procedure. First, you need to spend on a separate electrical panel and make podrozetnik.

Illustration	Description of the action
	Height sockets from the floor should not exceed 900 mm. If it is impossible to make concealed wiring cable can be laid in a special trunking.
	The cable from the cooking surface to derive the switchboard and connect to a specific machine and earthing.
	Install the Escutcheon and we clean the ends of the wires.
	Insert the bare wire into the terminal socket and clamping contact.
	Install outlet in podrozetnik.
	In a similar manner connect plug hob. Observe pairing of wires, ie if brown wire ( "phase") is connected to the left outlet, and blue ( "zero") on the right then on the plug must be respected the same location.
	Since we connect the hob to a single-phase network 220, then select the upper diagram, engraved on the surface of the device.
	"Zero" - When using copper or brass connectors, bundled with the panel, are interconnected tracks 1, 2 and 3 - "phase", and 4, 5. Connect the wires to the terminals in accordance with the color-coded.
	Close the terminal box on the cooking surface.
	Set the hob into the cut; we also check the power and operation of the instrument. The installation and connection of the hob can be considered completed.

Connecting a gas cooktop

When markup cutout gas appliances should be noted that from the wall to the edge of the device must be at least 55 mm. Inset into the enclosure for tabletop cooking surface is exactly the same as in the above cases. to a gas pipe connection shall conduct the Compliance Officers, of course, if you do not want to pay substantial fines and subsequently receive an order to dismantle. But the electrical part can be performed independently.

Wiring diagrams cooktops

Manufacturers hobs produce models that can be connected to the grid with a different number of phases. On the territory of Russia and the former Soviet Union there are two standards: single-phase 220 V, rarely - a two-phase to three-phase 220 V and 380 V. Electrical wiring in homes can have, depending on the number of phases and years of construction of houses, the number of wires and different colors. For example:

1. Single phase with 220 V:
   two conductors of the same color (Usually in houses of old construction). "Phase" or "zero" will have to find an indicator or tester;
   in new homes already use colored wiresWhere "phase» (L) denote brown or red wire "zero» (N) - blue or blue and ground (PE) - yellow-green. In older buildings, the wiring of the same color, so will have to determine the neutral probe.
2. Two-phase network 220 V. It occurs only in new buildings, and it is rare. "Phase" refers to the black and brown wire "zero" - in blue, and "earth" - yellow-green.
3. Three-phase network of 380 V. In this case, the "zero" and "ground" are the traditional coloring and "phase" to the same standard - white, black, brown, otherwise - yellow, red and green wire.

Due to these nuances of cooking surfaces are usually supplied without the power cord. Therefore, in addition to a dedicated wire for power lines, will need to buy a cable to connect the built-in plate to the wall outlet.

How to connect an electric cooker: the scheme for a single-phase network

In principle, connect the hob to the household power outlet with 220 volt snap. On the back side of the board you need to remove the cover, which is fastened by snap or with screws. After removing it, we will find the terminals for connecting the power cable (usually 6 pcs.).

№№ Terminals 1, 2 and 3 are designed for the phase conductor (L), №№ 4 and 5 - the neutral (N), a grounding terminal (PE) is indicated by an icon. But what if you have a dedicated electric line 3 wires and connectors for 6 pcs. For such cases, as a rule, included are copper or brass jumpers. If they are not, you can make them yourself from a copper wire 6 mm2. Set the jumper as indicated in the figure below, and attach the power cord.

How to connect electric hob with two phases

Two-phase cooking surfaces are rare, but in this case there is no problem with the connection. Just exactly follow the wiring diagram below. Before applying power to the device is necessary to double-check that the wiring in the outlet or junction box coincided with rasklyucheniem wires in the plug.

How to connect your own electric stove for three-phase network

Three-phase power is mainly used in the country cottages, and will need a five-wire cable with a section of each conductor of at least 2.5 mm2 for powering the cooking surface. Connection is virtually identical to the previous versions, and is as follows:

1. Phase conductors L1, L2 and L3 are clamped in the terminals №№ 1, 2 and 3, respectively.
2. №№ terminals 4 and 5 are interconnected by jumper copper or brass, and one of them is connected the neutral conductor N.
3. By № terminal 6 connects a corresponding grounding wire PE.

If the network cable and the input wire color, when you connect simply observe a combination thereof. If the house is old and the wiring of the same color, then you need to be careful and use the indicator or tester to determine the phase conductors.

Requirements for electrical connecting the oven and cooking hob

Before you make a choice of the cooking surface, you should decide a number of questions. You must correctly calculate the wiring, buy sockets, plugs and hob cable capable of withstanding heavy loads, as well as the RCD. In older homes the wiring is practically designed for a number of household appliances and power, which are in each modern apartment. Therefore, very often with the wrong approach, continuous operation takes place during the operation of the cooking surface induction machine, and when installing the RCD with inflated face value of the wire begins to warm up, causing fire. In addition, the switchboard must always be a ground loop, though many ignore the need to connect to it.

Since power cooktops and ovens comes to 7 kW, the experts strongly recommend to lay a separate line, equipped with protective devices. Therefore, if you can not upgrade an old household power and lay a separate cable, it is best to refrain from the acquisition of a powerful home appliance. Below we will look at what cable is required to connect the hob and the types of compounds as well as the requirements for plugs and sockets.

Fork hob

To connect hobs using plugs with the sockets, the sleeve connection and mounting boxes. The most convenient option in terms of operation and maintenance - plug. For example, at the time of wet cleaning is necessary to de-energize the electric hob and with a direct connection will need to constantly go to the switchboard to turn off the machine.

"If the power of the cooking surface of more than 3.5 kW, then a plug to the power outlet can be no question. In this case, you must be connected via the connecting sleeve or mounting box. "

fork plate

Power socket for the oven and the cooking hob

With forks we understand, but because they are useless without a power outlet. Low-power heating surface (usually with two) can be connected via a conventional earthing-pin 16 A, but most likely, it will always be heated. However, it will be difficult to start and tighten the cable with a cross section 6 mm2. Therefore, it is best to just take a socket and plug, designed for high power and current up to 40 A.

Outlet must be placed at a comfortable height, but not more than 900 mm from the floor and not on par with the hob. It is better to place it to the left or right of the plate. If it is assumed installation and the oven near the hob, the outlet should be placed below the level of boxes, but not too close to the floor, to avoid a short circuit from possible flooding in case of breakage water supply.

sockets for boards

The required cross-section of wire for electric stoves and ovens and breakers

To connect the hob to the mains using a three-, four- or five-core cable with copper wires. Number of cores and cross-section are dependent on line voltage, load current and power. It is also necessary and protective devices.

As already mentioned, for the connection of such a powerful home appliances like hobs and ovens, it is recommended to arrange a separate electrical and be sure of the cable with copper conductors. wire Size selected depending on the power:

• for the single phase power network with equipment of up to 3.5 kW is required trohzhilny cable wire section 2.5 mm2 (VVG × 2,5 or 3 PVA 3 × 2,5);
• for single-phase and two-phase network equipment capacity from 3.5 kW using a cable with a wire cross-section 6 mm2;
• for three-phase network from the equipment 7 kW or more is needed five-wire cable with wire size 2.5 mm2 (5 × 2,5 KuGVV or KuVV 5 × 2,5).

Between the hob and the switchboard is required to install the machine and a residual current device that will prevent equipment damage in the event of a short circuit:

• for single-phase network - machine A 32 A 40 A RCD differential tripping current of 30 mA;
• for a three phase network - machine 16 A RCD 25 A differential tripping current of 30 mA.

connection sleeves

The hob can be connected directly to the power supply outlet without using crimp sleeves. Some connect the wires together by a conventional stranding and insulation tape PVC. However, the sleeve connection is much more reliable, safer and prescribed PES.

To power the hob from the mains, you must first de-energize the room and check the indicator of the absence of voltage. Next, connect the wires by stranding observing pairing - "phase" - "phase", "nol-" zero "etc. down Connection conductors metal sleeve wear, compress well using a special gun and insulated

Important! Wire before crimping should be well cleaned. crimping sleeves should only be carried out by a special tool, and in any case, not a pair of pliers, tongs, etc.

Connection through a wiring box (terminal)

Another way to connect the hob to the mains - the use of the mounting box KLK-5C. To work does not require any special tools other than a screwdriver, a wire can be easily and quickly disconnected if necessary.

As can be seen in the photo, mounting box - it's quite compact, practical device with a completely normal appearance. It has a twin terminals are identical to those that are on the hob, which makes the connection quite simple - you need only observe pairing of the wires and, in principle, everything.
