Scheme of installation of electrical wiring in the bath with their own hands, materials and advice

e-1 At purchase of a system / materials each builder is guided by own criteria. Someone value is important, someone is interested in the opportunity to do everything by themselves and save on it. Opinions vary, including the most successful project, and the location of the building on the site.

But what variant of the bath would be discussed( from wood, foam blocks, bricks), they are united by the general specificity of operation, expressed in elevated( and in separate rooms, excessive) humidity and temperature. In this article, we will consider all the nuances of self-wiring in a bath taking into account these features.

Basic installation rules

All lines are laid only in the open way, in rooms with excessive humidity( washing, paired) - along the shortest path.
In a bath it is necessary to install not only protective devices( АВ), but also RCDs.
Elements of the circuit are selected according to the protection class, not less: for lighting equipment - IP-54, for the rest - IP-44.

If the bath is erected from flammable materials, and wiring is laid in plastic cable ducts, then under the last( if fixed on the basis) should be placed strips of asbestos cloth( sheet).The same applies to the fastening of sockets, switches on wood.

Recommended cable mark for internal wiring - VVGng-LS or similar( for example, NYMng-LS) , not less than 1.5 "square".But this is only for fixtures( switches).For sockets - 2,5.If an electric oven or other device is connected, the cross-sections are recalculated, corrected for their power. In this case, separate "threads" are mounted for them.
As in the residential building, the wiring is done wiring the rooms. In addition, lighting lines and power lines are laid separately.
For each powerful device - its own AB and RCD.
In a sauna, with due regard for increased dampness, earthing and lightning protection must be provided.

Everything else( distance from the ceiling, floor, walls and the like) - according to the PUE.

Wiring diagram in the bath

In principle, it is no different from those that are made for private houses or apartments. And since it is developed individually for each object, it is enough to give only a few options for wiring in the bath. The reader should compile the concrete scheme independently, as well as mount it.

What is prohibited

Mount the "hidden" wiring.

e-7 On some thematic sites there are tips for its laying under the plaster layer. The expediency of such recommendations is questionable. First, there are general rules. Secondly, the gasket is conducted only in corrugated( plastic) or boxes. What is the thickness in this case should be plaster?

Pull the wiring over the oven.
Place elements of electrical / circuitry( automatons, sockets and the like) in the steam and washing, wires( cable) - lay in pipes( corrugated) of metal.
Use any connections( for example, spikes, twists), except terminal.

Useful advices for

If a sauna is only being built and several rooms, including utility rooms, are provided, then a suitable cable with veins of the order of 16 "squares" should be immediately put in. Perhaps, after a while, the idea will come to install( replace) with a more powerful model of an electric oven, a washing machine and so on. Therefore, it is advisable to focus on the future when laying electrical wiring.

The spreader / shield( introductory) is installed with the following requirements:

the installation site should be well lit, and of course( through a window or door);
the shield should be well ventilated;
access to it is absolutely free.
