wiring in the bath has a number of features.And this is connected mainly with high temperature and humidity in the room, which adversely affect the condition of the wires, as well as the specifics of flammable wood material that makes up the walls of the steam room.Correctly to the bath to hold the cable and mount the wiring inside - is vital.
Wrap the power cable to the building baths ↑
The ideal option would be ifthe bath will be able to conduct electricity from the main electrical panel through a dedicated line for this power supply.Get the power cable to bring it directly to the bath can be 2 ways "earth" when the wire is laid un
«Ground" method of laying ↑
This is the most reliable way, but it does not always fit.Previously on the plot should end all agricultural work and confirm the fact that the wire does not have to lead through the territory of a neighbor.Under the ground lay the so-called "cable with armor" brand VBbShv with 4 copper conductors, cross-section of which is 10 square millimetersThis cable is quite expensive, costs about 200 rubles. / Rm.But it is extremely reliable and durable thanks to the steel braided, laid between its plastic shell.Accordingly, it will be unable to gnaw moles, mice and other rodents.Cables are not afraid of earthen shrinkage.
Not recommended for laying cable used metal pipes, as they are - collections of condensate, which reduces the service life of the wire.They may be used only in areas where the cable is on the pole or on the wall.When this is used in tube height is not & lt;1.8 meters.
The procedure for installing the cable underground is:
1. Rummages trench depth of at & lt;0.7 meters, the bottom of which poured sand layer of about 10 cm. Top backfilled wire in the same layer of sand.
2. makes entering the building through the cable into a steel sleeve.It is necessary to protect the wire at progress and complete shrinkage of the wooden wall.Wiring in the bath should be particularly careful and cautious.
3. The cable is freed from its "armor" immediately before starting the panel.Only after that the leads are connected to the machine, making the grounding and lightning protection.
Important!When installing underground cables eliminate the possibility of dangerous tensions, mechanical damage in the event of the displacement of soil: stockpile, placing cable in a trench in waves.
Cabling "air" means ↑
If you select a more economical way, deciding to hold the cable in the air, then you consider the following:
1. If the distance to the bath is more than 25 meters, it is necessary to put between the support intervals.Air laying wire by means of a so-called stretch marks, or else on porcelain insulators.
2. The cable must be located at a specific, regulated height.Above the roadway he can not be placed below 6 m above ground level above the footpath - 3.5 m (at least).K wire is fixed on the bath height of 2.75 m above the ground.
3. Typically used SIP - self-supporting insulated wire.Its warranty period is 25 years.Cable SIP (SIP-4, STS-3, STS-2A) have a special polyethylene weatherproof coating and special bearing elements are resistant to overloads.Its cross section should not be & lt;16 square meters.mm capacity - up to 63 amps.If the connection is a single phase, then the power will be equal to 14 kW, and if the three-phase - 42 kW.The main disadvantage is their SIP problematic start-breaker of the low ductility, they are difficult to bend.
4. CIP is introduced into the bath room (but not in itself the steam room, as there can not be placed aluminum wires) through the metal sleeve.And in the steam room are entered completely different conductor - NYM, or VVG NG.It has proven its cable VVGng-LS 3x1.5 section (it is used for connecting lighting) VVGng-LS section 3h2,5 (used to connect the socket).Insulation VVG does not support combustion, the level of smoke in the event of corruption is very low.To move, use sealed connectors such as "copper-aluminum", CIP have to mount on the anchor clamps, so-called tensioners.
Wiring in the bath: the main stages ↑
During wiring directly into the indoor baths allocate such as the steps:
1. Install shield;
2. The layout of the panel;
3. Connect fixtures;
4. Connecting sockets;
5. Connect electric.
Terms installation of a switch ↑
from the distribution panel will be powered energy system bath.It is important to choose the best location for its installation, subject to the following requirements:
1. access to the shield should be free;
2. The place should be well ventilated;
3. Shield prohibited positioning in the steam room and the other fire facilities;
4. well-lit room with a shield.
usually guard set in the recreation room.It consists of protective devices, induction and exhaust machines.Its upper part is to be 1.4 m - 1.8 m above the floor, no less.
If wiring in wooden bath single phase in the supply cable must be present for at least 3 wires.In accordance with the new Standard color phase conductors to be gray, but can get wires from old stocks with white or brown residential phase.This core is placed on top of the terminal opening of the machine.With lower terminal phase conductor using a jumper is moved to the upper part of the flue terminal machines, or diluted through the distribution booths in the machines.Zero vein (blue color) is placed on the zero block, protective conductor (yellow-green) - on the protective pad, or else welded bolt on guard.Phase conductor cable extending to a load connected to the lower contact of machines.The exhaust and inlet cables fit into the panel very carefully, and then output from the panel through the corrugated pipe.RCD and controls must be installed according to the level of load on the cable.
expect the load on the cable, choose the desired cross-section
load must know to choose the right cable size.There are special tables choice of the section of wires, where it is calculated depending on the intended power devices.On appliances usually indicate their power consumption, so it is worth paying attention.
1. If the bath is expected to post only the lights, the total capacity will be about 1-2 kW.
2. If you do not use an electric furnace, the total capacity will be around 5-6 kW.
is desirable to take into account a 20% power reserve.For example, if the total power of 5 kW in the bath, the wiring to expect better value 6 kW.With this power cable suit VVGng-LS section of 3x4, that is 4 mm square.Cables extending the coverage, it is desirable to choose a section of 1.5 sq.mm (3x1.5) in the socket - with a section of 2.5 sq.mm (3h2,5).
selects the input automaton
You need to know the total power.Then calculated by dividing the current total load on the voltage.For example, 6000/220 received 27 A. But the machine should be chosen with a margin - about 32 A. Choosing the waste is carried out by groups of machines based on the same principle.It is desirable to sign in each panel machine, indicating for which group he answers appliances.
also close to the shield should be wiring diagram baths.Do not forget to connect the protective devices that disconnect the power source in the event of contact with water.This will help save lives in case of emergency.From fire to protect the RCD current cutoff.Make sure the wires in the terminals terminals have been well documented to avoid heating portion of loose clamp.
Wiring electrical cable from the panel ↑
should initially be drawn diagram of the wiring in the bath.In preparing the plan and further the practical implementation of the plan layout, consider the following:
1. cabling extending from the panel, it is recommended to do one piece.
2. If the bath wooden walls, the wiring can be open, conducted over the wooden walls.It is forbidden to place the wires in PVC pipes.
3. If the brick walls - wiring for a bath is hidden, hidden behind a layer of plaster.
4. All cables should be installed in a strictly vertical and horizontal position.Inflection and twisting should not be, as indicated in the latest edition of the SAE instructions.From raspaechnyh boxes running wires is permitted only at a right angle.
5. Try to place the wires in the least visible locations.They should not be installed in front door, closer than 50 cm from the metal tubes and batteries.
6. switches and sockets, as well as mounting boxes may not be used in areas other than high levels of temperature and humidity.Over time the moisture accumulated therein and inevitably followed by short circuiting.This applies, above all, the steam room.Therefore, they must be placed in a waiting room or rest rooms.
7. Connect wire strands should be welded or soldered.
8. Use protective guard vanishing.
9. Do not install the wire above the oven.
10. The wires should never be placed in a metal shell and tube.
Installation and connection of luminaires ↑
class protection for the bath should not be & lt;IP-44, and power is not & gt; 75 watts.Plafonds to use only the glass, and the case - a metal that is connected to the protective conductor of the wire.Plastic body may be deformed.Should not be placed on the ceiling lights, but only on the walls, as the ceiling temperature is usually the highest.The steam is usually used low voltage (12V).For this purpose, useful step-down transformers, which are placed outside the steam room.Also, in the steam room should not be installed fluorescent lamps.
connection sockets ↑
sockets can be installed only on the walls in the dressing room or break room at a height of 90 cm. Their protection class must be at & lt;IP-44.It is advisable to use a wall outlet with lids.
Standards connect electric ↑
To connect an electric furnace, the wires need to withstand high temperatures (up to about 170 g), and high power consumption, which amounts to 4 kW on average).For these purposes fit the wiring in the cable channel with a single wire marks PRKA, PMTK, PRKS or RKGM.Copper cable cross-section 3 * 2.5 mm can withstand about 5 kW load.Acceptable stretch wire type PMTK to mounting box, which is located outside the zone of high temperature and humidity, and from the box to the panel to conduct a normal cable (VVG 3h2,5).
