Connecting the hob and oven .Wiring , sockets

Every housewife prefers to be in the kitchen has been equipped with modern and comfortable equipment, which allows to save time cooking.Engineering thought the biggest home appliances manufacturers (Samsung, Zanussi, Bosch, Elektrolux, Hansa) does not stand still, and every year there are more and more sophisticated instruments.

To ensure safety and reliability, it is necessary to know how to connect the electric stove or oven, what are the characteristics and basic key points:

• first , connect the hob to the power supply must necessarily involve the presence of a protective earth.Find out if there is or not, it is possible, considering the number of contacts on the plug or in the socket for electric stoves.Their number must be odd.

For example, the number of contacts 220V - 3 for 380V three-phase network - 5.

grounding pin on the plug may appear in the form of a pin, a little longer than the others, or metal plates on both sidesplug housing.

wiring old buildings or apartments it was not always provided by the presence of the ground, so you have to lay new electrical cable from the switchboard.This wire must be included in the total network using the protective device (RCD) or a circuit breaker;

• second , if the maximum electrical power of more than 3.5 kW, the required laying a separate power cable as standard wiring 220 in the apartments can become very hot and damage.And connect the oven a little power can be without laying a single cable;
• third , this cable should not burden other electrical appliances in his circuit breaker must be installed (to connect the oven power from 3.5 to 5 kW - machine to 25A, and more powerfulplate - 32A).

algorithm connecting the hob and the oven

How to connect the oven or stove to electricity independently?Most new or separate cables and socket for the hob recently renovated apartments have already been installed and is suitable to buy a plug.However, until now there are no kitchen these devices.

general procedure in such a situation the following:

• Check for a voltage of home appliance is designed and what connection method is recommended by the manufacturer.Such information can be gleaned from the user's manual (user guide), as well as examining the place of connection on the device.

Hobs may be designed for connection to the network 220 and 380, and household ovens - for voltage 220V.The terminals for connecting the plant with the power cable already fitted with jumpers, which implement the scheme for inclusion in the 220V socket.

Common kitchen in apartment buildings do not have a network of 380 outlets (this is contrary to the current SNP), but can be equipped with 220V power outlets.

• Perform the electrical installation in a single network circuit breaker (AZS) and lay it on a separate cable.Nominal force the gas station and a way to connect the current depends on the intended load.

to connect the electrical, power does not exceed 5 kW, this value will be 25A, a cross section of the cable core - no less than 2.5 mm2.In the case of more powerful devices - 36A ​​or 40A, the cross section - 6 mm2, respectively.

More information about the selection of cable cross-section available here

Mark cable should be selected non-flammable, double insulated, moisture resistant, for example, VVGng.To connect the cable to the same phase conductor 3 must contain, for implementing circuits with two phases requires cable conductor 4, and for three-phase connection - 5-conductor cable.

• Install outlet and connect the plug to the cable.How to choose the right plug and outlet will be discussed below.

Some electricians prefer you to connect cooktops and ovens through terminal blocks attached to the wall without using a plug and socket.This method is not convenient in operation.For example, when the need to dismantle the hob will have to go into the terminal box and when installing all the switch again.With the plug-type connector socket such procedure is much simpler.

How to install the hob.Method of mounting

Hobs - a kind of built-in appliances, respectively, prior to connect electric stove, you need to understand the technology of this "integration", or - the product installation in the kitchen cabinet.

to perform tasks with your hands need a small set of hand tools:

• electric drill;
• jigsaw;
• screwdriver;
• knife;
• Rulers, triangles, pencils and cardboard.

Installation is carried out in three stages:

markup future cutout panel.It should be with a ruler to accurately measure the width and length dimensions for the installation.

most convenient to mark the pattern, which is not difficult to make out of cardboard.Some models of these templates can be included in the package.

Draw a line on the table pedestals next section with the help of line and polygon.You can do overlap, not more than 1 mm, to allow easy entrance panel.

Carving a niche for panel installation.We must start with the drilling of holes in the corners of the marked rectangle.The diameter of the drill should be at least 9-10 mm.Drill Type - wood or metal.

next step - cutting out jigsaw.Sawing jigsaw should have small teeth and the target of the finishing cut.To prevent the formation of small chips of the future place of cut can glue masking tape.

sawing jigsaw insert into the drilled hole, the sole press firmly to the countertop and then start cutting, gently holding jigsaw along the lines marking at low speed.

Installation and mounting panel.The PROGRESS window insert a cooking stove, and the place of conjugation of the working surface with top seal a special seal or sealant based on silicone.If necessary, you can expand the landing window with a file or re-propyl jigsaw.

Bottom panel securely to the table top clamps from the kit.After mounting, remove excess sealant with a rag or a knife cut the protruding portion of the seal.

How to implement the wiring diagram of the hob and the oven

According to current building codes (SNIP), connecting electric cookers should only be performed by radial.In other words, the power of the cooking surface must be allocated a separate cable that stretched from the main distribution switchboard.It is strictly forbidden to install a cable outlet and other electrical consumers.

Wiring diagrams oven and hobs in the apartments include the use of only a single phase 220V.

If the input power terminal block cookers originally collected for use in 220V, it is necessary to remount it to work with a three-phase network 380V.To do this, loosen the screws with a screwdriver and remove the terminal clamps jumper.As a result, must remain 5 connection points.

Also, for a more even load distribution, you can mount the circuit using 2 phases, and ground zero.

In connection diagrams given in the instruction manual, referred to as Phase 1L, 2L, 3L, neutral conductor - of N, and ground - a sign of "land".

happens that some manufacturers do not install the terminal blocks, and the appliance is removed from the multi-colored wires, which can be connected to each other.

To identify the purpose of the wires, you must remember that the wire ground - yellow, with longitudinal green stripe, color «zero» - blue or blue, "phase"painted in any color.

panel to the radial cable can be connected through the box terminal blocks or plug.
No differences in the schemes and how to connect the stationary plates and recessed surfaces not.

plate to the wall outlet or the box is connected via the power cord.If such is not part of the product, it must be purchased separately, guided cross-section selection rules and the number of veins mentioned above.On the same cable mounted plug.

What set the socket for the hob and the oven?Tips for Choosing

All outlets are designed for AC power 25A considered more power.By way of installation, they are divided into:

• external overhead.Installation of outlets of this type is made directly on the wall of the plane.They are convenient to use when wiring the open way.In addition, these sockets are the safest for installation in wooden houses and in areas with high humidity.It is this type of outlet has the best moisture and dust protection;
• interior, set in Special Enclosures, built in the thickness of the wall.Find the most widely used in brick and panel houses in the decoration of walls sheet materials, such as gypsum fiber board.

By appointment and design features sockets are divided into:

• intended for use in single-phase 220V networks;
• designed to work in networks of three-phase, 380V;
• have separate contact for ground or without it;
• with clamps securely hold the talk with a fork.Fixation is threaded or push-button, with the union nut;
• integrated devices, such as the RCD trip time relay;
• with shutters, closing inlets outlet.It is very convenient to use this type in households where there are small children.In such a socket can not insert any other object besides a fork.

Before you buy a socket for electric stoves, you must make a choice that should be based on the following criteria:

• rated maximum current.For ovens (up to 3-3.5 kW), sufficient quantities in the 16 - 25A for the plate with a capacity of up to 7 kW - no less than 32A, and for more powerful units - 63A.In these sockets and plugs appropriate for them contact pins thicker insulator material is more refractory;
• number of work phases.For connection to the 220 V socket and the plug is used with the three contact groups, and in 380 networks - with five;
• protection.Immunity from electrical influences designated IPXX code, where XX - digits.

first encodes a degree of protection against ingress of solid objects body.

second - the code of protection against the ingress of liquids.The more numbers the better the protection class.

For example, 00 - protection is completely absent, ie, the contacts open...A IP68 - maximum degree of protection in which absolutely ruled out the possibility of falling into the sockets and plugs of dust and water (even at full flooding).

cable is connected to the plug and the socket in several ways.

first way - cable core is released from the isolation of 0.5 cm, is inserted under the clamping screw and clamped.The second method is more reliable: the conductor is cleaned of insulation 1.5 cm, wrapped around the ring and screw presses.the contact area will be more reliable contact.

socket or terminal box should be mounted on the wall near the stove, securely with screws or screws, so as to fulfill the following conditions:

• on socket or box should not be exposed to liquidplates or washing;
• outlet (box) must be accessible for the electrician, but remain hidden, not mind.
