in how to lead the wiring in the house or apartment are important wiring accessories.For example, connecting the wires be sure to use boxes that protect the joints and provide access to them.
deciding how to change the wiring in an apartment or in a house, of course, chosen not only new wires, but also new outlets and switches.
as to how much to change the wiring, the lion's share of the cost of some types of wiring make it high-quality boxes, switches and sockets.
example, is the case with retro wiring, meter wire which costs an average of 80 rubles / 25 hryvnia, and a porcelain rotary switch could cost 2,000 rubles, and even more expensive.
Price rewiring depends on the volume and complexity of the work required of materials is about half the amount, and the grounds on which the wiring is carried out.
wiring is external, driven by air or in the ground, and inside - open or hidden .
in the panel house in the concrete wall and Khrushchev with
to manufacture fireproof products used porcelain, metal and non-flammable plastic.
Particular requirements for wiring accessories are presented in wet areas, such as in the bathroom, bath, sauna.Directly in a room where washed or steamed, wiring accessories are not installed, there is carried out only lighting, and lighting must be a high degree of protection. sockets and switches are mounted in the hallway or waiting room and should also be splash-proof.
Comparing how much material for hidden and open wiring, it can be said that cheap will not do neither the first nor the second option.As already mentioned, by wiring accessories, outer can leave even more.However, when the lead wires can not be hidden, it is not profitable or causes additional difficulties applies external wiring and related products.
switches for outdoor porovodki
in how to carry out the installation switches for external wiring is no big deal.How and when the hidden wiring, wiring diagram helps determine the number of breakers and their placement.
strict rules on where to install the switch there, but usually it is set at a distance from windows and doors and in a way that opens the door did not cover it.The standard height of placing the switch - 50-80, or 150 cm.
switch is mounted directly to the wall with a flat Escutcheon made of metal, plastic or wood.Escutcheon size is usually slightly larger than the cover to secure it to the wall with only two screws or dowels, nails.
mechanism switch joins Enclosures and terminals are connected the wire ends. then dress frame in which to break down the window for the passage of wires and inserted the key switch.
Sockets for external wiring
Sockets for external wiring are installed on the same principle as the switches.They are mounted on a flat Enclosures, screwed to the wall.
sockets for external wiring to be grounded or not, for a single-phase or three-phase network for different current capacity, etc.
network in homes are usually single-phase current, which can withstand a standard socket, higher possible load on the wires going to it, and the ground - is recommended for protection against electric shock when using household appliances, but not necessarily.Placing outlet taken at a height of not less than 30 cm. From the floor, the number of outlets depends on the number of connected appliances.
As can be seen in the diagram, usually located on the outlet end of the branches from the main wire.But sometimes the question arises, how to hold the wiring from the wall outlet, for example, to establish a close another outlet.For this purpose parallel connection: tips installed wires connected to the ends of the wires supplied to the outlet, phase to phase, zero - to zero. But here you need to take into account the load on the network.
If you need additional outlets for a powerful technique, to drive them from the outlet should not be - they need to conduct a separate group from the board.Furthermore, compounds for the strength strands connected wires must be of the same metal.
If you still connect the aluminum and copper wire, then the terminals with a special coating.
