The power socket for electric stove: types, device, tekhnichekipa of norm, rule of connection

Housekeeping Hits: 145

Electric stoves — household appliances power-intensive and very powerful. Therefore sockets of special version — power are used to their connection. Their difference from normal products of this type is that they are equipped with the strengthened terminals calculated on current of 10-25 amperes and above. It is necessary to turn on such sockets in household network, of course, with observance of certain rules.

In specialized shops it is possible to buy power sockets of several types today. It is necessary to choose the similar device taking into account its design, degree of equipment and purpose.

What it is necessary to pay attention upon purchase to

Choose the power socket first of all taking into account the power consumption of the electric stove. It is considered that:

plates with power up to 7 kW should be connected to the power supply network via sockets with current in 32 A and possible short-term loading in 63 A;
for plates with power over 7 kW it is better to choose sockets with current in 63 amperes.

When choosing the similar device it should be taken into account also to what type of household network in the subsequent the plate will be connected. Today on sale there are both single-phase, and three-phase power sockets.

Versions on design

Such devices first of all are classified by installation method. In this plan distinguish sockets power:

open type;

The first kind of devices for electric stoves is used rather seldom. Open power sockets generally only in the country houses constructed of bar or log are mounted. In such buildings the wiring is often stretched in the open way. That is the cable is laid on outer surface of walls. Respectively, and power sockets including intended for electric stoves, in stacked and log houses, consignment notes are used.

In city apartments the power closed devices are in most cases used. Such sockets with preliminary gouging of niche in wall in podrozetnik are mounted. At the same time devices of this version are connected to the cables passing in walls in indents.

Types of power sockets on equipment degree

Besides devices of the closed and open type, distinguish:

simple sockets and with grounding;
with protective blinds;
with the pusher;
with the timer;
with OUZO.

In most cases electric stoves are connected to network via normal power sockets or with grounding. In hard-to-reach spots models with the pusher and blinds can be also established.

Basic rules of connection of plates

Installation of electric stoves in premises with observance of the following rules is carried out:

cable for such device it is necessary to use only copper;
to plate from guard the separate line is stretched;
wiring for electric stove has to be used only the most qualitative, with a section of 6 mm;
in guard it is necessary to install the switch on 32 A.

Choice of the space for the socket: technical norms

Most often sockets establish under plates or in one of table-top lockers in wall. At such arrangement it will be most convenient to use the power device in the subsequent.

To have anyway sockets in kitchen, according to standards, follows:

far from sinks and sources of fire;
not closer to 60 cm to gas pipes;
far away from radiators of heating, sewer or water-mains.

Over table-top the power sockets mount at the height not less than 5 cm, and over floor surface — 15 cm. Such method of installation excludes possibility of flowing in the water device, for example, when cooking or cleaning.

Connection of cable of fork in single-phase network

Household networks in premises are most often used single-phase. Respectively, and cables in apartments and owner-occupied dwellings are usually applied with three veins, and forks and sockets — with three exits. Carry out connection of electric stoves in single-phase networks so:

open terminal box of plate on the back panel;
weaken contacts in block;
smooth out cable and separate veins;
connect cable wires to contacts.

When performing connection it is worth remembering that red or white wire — it is normal phase, blue — zero, green — grounding.

Connection of cable should be carried out according to the scheme specified by the producer on back surface of plate under box of terminals. At import plates the phase is designated by letter L, and zero — N. The contacts noted thus on schemes from producers usually happen a little. Both phase and zero wires can be connected, to any contact designated by the corresponding letter. The terminals of one type which have remained free just connect further bridges to the worker and with each other.

Connection of the single-phase socket

Actually power socket for plate in single-phase network is connected as follows:

the right extreme terminal is done by zero;
connect phase to the left extreme terminal;
the top terminal is connected to earth wire.

Wires in fork from cable attach as appropriate. It is necessary to watch it as it is possible more attentively. The discrepancy of wires will lead to short circuit.

Connection of the socket and fork with cable in three-phase network

In this case the cable of household network usually has five veins. Three of them at the same time represent phase, one — zero and one more — grounding. In this case connection of plate is made as follows:

also it is uncovered connection box on back surface of plate;
phase wires of cable are fastened to conclusions of L1, L2 and L3;
crossing points between phase terminals are removed;
zero joins as well as at single-phase connection.

Bridges between phase conclusions if they are, should be removed surely. Otherwise at connection of plate, as well as in case of discrepancy of wires in forks and sockets, there will be short circuit.

The socket at three-phase connection is installed so:

phase wires of cable are connected to three nearby contacts;
zero joins the top contact;
grounding is brought to the lower contact.

Of course, with the three-phase socket it is necessary to use also three-phase fork. At accession of cable to such device it is necessary to be the most attentive. All phases, zero and grounding in the socket and fork have to coincide.

Rules of mounting of power devices which should be observed surely

Installation of sockets for electric stoves — the procedure very responsible. It is worth carrying out such connections by the hands with certain experience of work with current household networks. Mistakes in this case can cost much. It is necessary to mount the socket for electric stove most accurately, qualitatively and with respect for all put technologies.

First of all it is necessary to install power devices so that they did not dangle at all. Have to be attached to wall of the socket most strongly. And of course, it is impossible to use the power devices which are dangling on wires for plates.

Bolts at accession of cables to terminals of plate, the socket and fork should be twisted as it is possible more densely. Otherwise in the subsequent at operation of the electric device there can be wiring ignition.

Rules of installation of the socket of the closed type

Devices of this version are used at connection of electric stoves most often. The niche under the closed socket is done with use of the perforator with special nozzle. The volume of the last at the same time has to correspond to the volume of podrozetnik.

The podrozetnik is established so that its edge was located 4-5 cm more deeply than edge of niche. Previously in it openings for wire are cut out. Podrozetnik in niches usually on mix of alabaster and medical plaster fix. Further in them mount sockets.
