Key conditions for connection sockets

Projects of old construction houses are not included outlet installation in the bathroom for two main reasons:

  • first - the old housing facilities are not provided with the grounding system;
  • second - in those days there was no powerful stationary appliances, "fed by" of electricity.

Used two or three decades ago, household appliances did not involve fixed installation in bathrooms, due to their intrinsic high level of humidity.

Current regulations and standards allow to place the point of connection in areas with high humidity, but subject to a number of mandatory rules:

  • Only connect to a working harness made of three-core copper cable.
  • For mounting the electrical outlet is used, enclosures which differ reliable protection from moisture.
  • Electrical device is equipped with breaker tripping current within 10mA.
  • The power line is mandatory should be equipped with an earthing circuit to connect a powerful instrument carried through the protective contact.

Grounding - strict condition for installation sockets in the private bathroom, as well as in combination bathroom, in which there is excessive moisture.

Information on how to properly mount grounded receptacle We discussed in our other article.

Protective transformer copes In residential buildings, which is not provided by grounding, the task quench excess currents and off line and RCD device. The only thing - their level of security will be somewhat lower.

Proper power point device designed to supply the washing machine, prolong the service life of equipment and ensure the safety of users

The priority of a separate power line to the unit

Virtually all models of washing equipment, even for small modifications recommended device separate power lines with individual socket

The choice of cable to connect the power socket devices

The cross section of the cable for connecting the washing machine is selected, based on the maximum capacity of the unit. In the case of a lump of powering multiple devices of line power is summed, and the cable cross section is chosen according to the total value

Some irresponsible owners to plug powerful domestic units using the extension cords.

To connect a washing machine, relating to the number of high-power domestic appliances, an extension cord is not necessary.

It's uncomfortable and also dangerous. After all, when you connect illiterate and installation increases the likelihood of an emergency due to short-circuit, resulting in premature failure of even high-quality expensive Technics.

Terms of connecting technology

Automatic washing machines installed in virtually every home, so the installation of a safe and secure connection points is a necessity

If a family has a curious little restless, the presence of clutter in the public domain and does it finds special features.

The main parameters of safe wiring

Wiring in the bathroom should not only be well-functioning, but also safe.

Triggering of equipment in case of emergency

In case of leakage to the housing of the electric plant at the time of short-circuit or when touching the same part of the body

Select the type of wiring

In older buildings, constructed a few decades ago, is mainly used wire with aluminum conductors. They are not suitable for the connection of modern powerful equipment.

The washing machine may be connected only by a three-wire cable with a copper core.

You may also be useful information on what types of wires used for the installation of electricity in the apartment, considered here.

Connection via a separate line

In order to safely install the connection point for a strong domestic unit from panel apartment It should be kept separate power line and ensure its protection devices and wiring of the equipment

according to paragraph 1.7.40 of the current PUE in humid wiring is recommended to perform the closed method.

For this coming from the electrical panel cables are located in the selected Stroebe wall so that it was hidden or even partly comes to the surface.

This measure protects the cable from direct contact with water, which is known for its excellent conduction properties.

For the same reason, when installing a channel hollowed in the wood, for example, is not allowed to place in an electrically metal hose or a steel pipe cavity.

The wire can not be fixed with metal staples, devoid of rubber gaskets. Sami brackets must be corrosion-resistant coating.

Determining the cable cross-section

To withstand high electric load from the powerful domestic unit should be correctly calculated cable cross-section.

It is determined by the same principle as that of any other electrical installation, taking into account the expected load. Power washing machine is listed in the accompanying instructions.

Three core current wire

To connect home appliances cable is used in the bathroom, made of three copper wires, one of which is brought to ground

For laying power lines use only devoid of defects holistic wire. All places of interfacing carefully wrapped with insulating adhesive tape.

No intrusion of the bathroom and junction boxes, inside the hollow body which cables are connected according to the scheme of connected devices. Junction boxes are always placed outside the bathroom.

Procedure for determining the cable cross-section:

  1. Learn the power plug of the appliance. In most cases it is not more than 3 kW.
  2. In accordance with the look-up tables are selected cable section.

when connecting the socket strip determining the total power "of powered 'devices from them and then, guided by the same reference tables, determine the allowable cable section.

Even if the machine consumes less energy, experienced masters recommend to make headroom. It is not ruled out eventually obsolete unit can be replaced by a high-power new equipment.

Table for selecting the cable cross-section

To connect the washing machine, the thickness of which is less than 3 kW, is used primarily three-wire copper line of 2.5 mm cross section

Only copper wire is recommended for the connection. Compared with aluminum, "fellow", he is preferable in that it has the best conductive properties.

Copper wire with a smaller cross section capable of withstanding high voltage: 1 mm section 2 kW load. That is why the place packed in Stroebe wire will occupy half. In addition, it is resistant to oxidation and the assurance of electricians has a lifespan of over 30 years.

RCD and power machine

The cable leading to a separate line WC, inside apartment is connected to a distribution box through the emergency stop device (RCD).

The design of the RCD

The main purpose of the RCD - protect "energized" from the mains electrical short-circuit, and households from the risk of electric shock

The leakage current of the protective device for connecting lines when you need rapid protection, should be 10 mA. This is due to the fact that an apartment sanitary characterized by increased humidity, due to which the room is one of the premises of heightened danger.

Irritability AC man feels already at a value of 5-7 mA.

If the bathroom "fed" group line, the maximum leakage current for connecting the wiring should be 30 mA. Such devices are less than 10 mA, but also triggered not so fast.

Driving system response

The apparatus operates under overload at 10 mA, preventing failure of the units connected to the power and occurrence of fire due to a short-circuit

To install the private houses and apartments is most often used model, combined with the machine to protect the wiring - differential switches.

You may also be information about RCD differences of Emergency circuit breakersDiscussed in our other article.

Modular devices provide protection for three "front", from overloading the power supply from exceeding the permissible value of leakage current and short circuit on the line.

Outlet, equipped with RCD

Some manufacturers have outlets that are already equipped with a protective RCD, although the price is much higher than stationary models

In the absence of an apartment stationary RCD in the distribution switchboard, use a portable RCD type. They are connected to an existing outlet, and then you are connecting electrical systems.

But in itself the RCD is not a complete protection. To protect the wiring and on the unit by short-circuiting set a separate circuit breaker has tripped.

Application of circuit breaker

Automatic tripping pick up, focusing on the padded section to an outlet cable and load the mains

Traditionally used machine 16A. In any case, the operating current nominal RCD must be one category higher than the rated current of the induction machine.

installation connection points Places

When choosing a connection point placement is crucial not only to the proximity of "Energized" household appliance, but rather a distance from sources of moisture and height relative floor level. In a joint bathroom has only 1-2 such safe places.

When selecting a location point of connection are guided by the following parameters:

  1. All electrical outlets for connecting home appliances placed at a height of not less than 60 cm from the floor. Such a requirement is due to the fact that in case of a breakthrough pipes and heavy leakage to minimize contact with electricity, which can trigger the occurrence of an emergency.
  2. Regarding the objects that are sources of water or spray outlet arranged, maintaining a distance of 60 cm. This solution also reduces the risk of moisture ingress to the connected device, making its operation more secure.

When determining the height of the installation socket to be guided by the principle "the higher the better."

Quality repairs in the apartment is still not a guarantee that the point did not rush the flow of the total pipe or does not shed "waterfall" of neighbors living on the floor above. Therefore, some experts recommend to equip the power socket at a height of 130 cm above the floor level.

The conductive properties of water

Pure, water devoid of impurities is sufficiently strong conductor of electricity, but the presence therein of complex chemical compounds and salts further increases its conductive properties

When designing the wiring in the bathroom should be guided Clause 1.7.47 of the current PUE.

According to it, the room is divided into 4 areas:

  • Red zone - referred to as a zero, it is located within the basin, bath and shower area. It is impossible to place any wall outlet.
  • The first zone - directly above or under the shower, a bowl bath capturing area of ​​radius 0.6 meters. Allows the installation of the equipment needed for plumbing, power within 12 V. Sockets in this area should not be.
  • Yellow or second zone - located at 60 cm, it is connected water-heating appliances. Sockets to install is also impossible.
  • Green or third zone - by "2" area is located at a distance of 2.4 m in it have all outlet IPX4 standard household aggregates "feeds" of the network, connected via an RCD with earthing contact..

Sockets are not supposed to be placed on the cold walls, which accumulates on the surface of the condensate.

Scheme space zoning according RB

Installation sockets and the various control devices can be performed only in the least dangerous third zone bathrooms subject SAE requirements

Sockets are used to connect the washing machine in the bathroom must meet the following requirements:

  • housings damp proof sockets provided with protective covers to warn the penetration of moisture.
  • The inner part is isolated devices dense rubber gaskets, which minimize the probability of occurrence of a spark between the contacts.

The level of protection damp proof sockets defined «IP» marking. The higher the numerical value, the more reliable device. Thus, the model «IPX1» class protects only small splashes and «IPX4» - are not afraid even a direct hit by water jets.

Table options sockets models

The designation «IPXY» indicates moisture protection class ( «Y») and dust ( «X»); for installation in sanitary rooms setting «Y» to be not lower than grade 4

Subtleties connection socket for a washing machine

When planning to connect a washing machine in the bathroom at home, which Bole 20 years, first of all check the wiring carefully. Most likely, there are aluminum wires.

They can not be used for the connection of high-power devices, among which belongs also a washing machine. Because the conductivity of aluminum wires almost twice lower copper, and the appearance of the surface oxides on the value of another decreases.

For laying the power line will need a cable with aluminum conductors thicker under the connection of washing machines than with copper, which is no good effect on the total cost. Quality wire connections It must be beyond reproach, to avoid overheating.

When operating the power point will have to be checked regularly and stretching screw terminals.

Burnt ends of aluminum conductors

Aluminum wire is mandatory to be replaced, because for such a long service life of the alloy loses its elasticity and just crumbles

Be prepared for the fact that the replacement of outdated aluminum wiring on the copper analogue costing a pretty penny. But it depends on the security of the household and the normal operation of equipment.

Some masters in a bathroom establish a single point of connection for all electrical appliances. For this paving wire section 2,5 mm, to which is connected a loop manner socket block, used for "powering" not only the washing machine but also the other electric devices.

Skilled craftsmen are not recommended to do it, and yet lay a separate wire to the Council by the washing machine.

The circuit-wiring

If all you plan to put on a single line several outlets, pre-Calculate the total power at the same time working appliances

When several receptacles connection point is desirable to place as compact as possible. For socket strips can be summed panel and underfloor heating control.

As the protective element can be set to switch itself outlet. But it should be considered only as a safety option, acting in addition to the overall security system.

installation connection point technology

At the time of installation of sockets in an electrical panel must already be automatic or RCD, and the wire withdrawn in a bathroom.

Before attempting to install the connection point, make sure that the wire is not under stress, touching the bare ends of the cable sheath from the display using a screwdriver

Step # 1 - cable laying and installation Escutcheon

To perform the flush in the cavity walls with doing a punch Stroebe. It paved the way for the smallest on the ceiling parallel to the floor surface.

To the outlet line is lowered straight down perpendicular. Wiring fixed in Stroebe using plug-clamps.

To identify the location of the sockets, the center laid strip applied enclosure. With the help of a marker make a mark for drilling. Outlining outlet point placement, via the punch equipped with a 68 mm D a crown, doing a hole in the wall.

Drilling niches using the core drill

With the core drill can be done in the wall of the large-diameter hole quickly and economically under installation Escutcheon standard planting size

Wall to make holes cleaned of residual dust and the shattered wall elements. In the prepared seat mounted Escutcheon.

Escutcheon choice depends on the type of wall. For setting in concrete mounting blocks used without fixing elements. Plasterboard - plastic cups equipped with clamping plates to allow bonding with the back side of the sheet. More about technology installation Escutcheon You can read in another article.

Installation of "glass" and the establishment of wire

Escutcheon fixing in the wall with the presser foot, or by coating the surface of the putty or alabaster solution was purified by the internal cavity of the box and display is carried out

Installed Escutcheon will be hidden terminal block for wiring connections, hidden in the wall.

Step # 2 - Connect the terminal block

With socket housing removed decorative elements, leaving only the terminal block. At terminals weaken fixing bolts with which will be fixed by the bare ends lived summing up.

Denuded of braided cable ends

The ends of the electric cable via jumper side cutter knife or trimmed by braiding, directing them in the opposite direction movement of the tool

For easy connection of the lead wire insulation is made in different colors. The ground wire is colored green and yellow braid phase represented by red or brown shell, and a zero - in blue or blue insulation.

Derived from the plastic "cup" the ends of the wires are led to contacts and is inserted into the terminal. Phase and neutral wires are connected to the current-carrying terminals: phase right, neutral on the left. The grounding conductor is connected to the terminal marked with the abbreviation «PE».

Summing up the protective conductor

ground conductor connected to the upper or central terminal equipped with "mustache", fixed to the apparatus body

In no case do not connect the "zero" on the ground terminal. Otherwise, in the case of burning-off workers "zero" in the panel, the housing is connected to the network machine will punch reverse "phase".

Socket housing connected with contacts fixed to the Escutcheon screws or spacer lugs. After checking the quality factor fuser connecting contacts and bolts in the connector.

At the final stage, attach the decorative cover.
