Installation electricians in apartment
Carry out the electrics in the apartment is notspecial work for those who can handle the tool. Installation electricians in the apartment There are two ways: the hidden and open. By the method of hidden gasket refers vmurovyvanie wiring in the walls, ceilings and voids under the floor and gypsum boards. To open the installation methods include wiring and cables in special boxes, cable - channels, using brackets and clips. Both of these methods have their advantages and disadvantages. To perform the installation in the first place need to push all the furniture and appliances from the wall when being overhauled apartment, then remove all debris.
Hidden method of laying
This method of mounting the most dusty and dirty,as it will have to Stroebe walls and ceiling or tearing the floor covering. So do his best during the overhaul of the apartment. If the project is scheduled distributing electricity on the walls, then put on the walls and ceiling space for the wiring, take into the hands of hammer or grinders and cut grooves of a certain width and depth. Depth choose on the basis that after the installation of wiring or cable layer of plaster will not be more than 10 mm, the width is unlimited. Designated raspredkorobok sockets and cut out with a special crown. We remember the supporting walls and Stroebe do not too deep in them.
The flat panel houses floor deckshave internal cavities, which can also lend the wiring for the lights. Today, more popular monolithic construction with brick to interior floors, in such apartments Stroebe can be done in all the walls, the main thing is not to catch bearing monolithic beams. The most economical option is flush-mounted installation wiring under the floor. The main thing that should be noted in this case - the presence of the corrugations of each wire. This is done for convenience in case of repair or replacement of wires and extra insulation.
After Stroebe be equipped, canready to install the electrical panel and the installation of lighting wires. Sam flap can be hinged or embedded in the wall. In new houses, a special niche for him, and in his old can be secured to the wall with screws. Inside the panel set up machines, and from which will depart wires VVG-3 * 2.5 in the outlet, and the main highway. From raspredkorobok to switches and lighting paving wire VVG-3 * 1.5. For high power stationary tools are paving the individual lines of VVG-3 * 2.5 cable.
In the field of installation of connections do releasewire 15 - 20 cm. Now connect the wires to the junction box in a single network. The easiest and most secure connections will use the CV. That during the connection wires do not mix, they can hang a tag with a specific label. Thereafter, using a tester to check the entire network errors and damage. If all goes well, then walled up all the wires, set the switches on the place, receptacles, lighting.
For areas where it is forbidden or impossiblepave the way to a hidden wire, used outdoor wiring. For these purposes boxes, cable - channels or special clips. Installation is quite simple and is carried out only on the walls and ceiling. The first thing you do is outline the place zasverlivaem wiring and mounting holes with a pitch of 40 - 50 cm, if the space for the wires is less than 0.5 m, then take a step of 15 cm for the two fixing points. After that fasten to the wall or ceiling ducts, cable - channels or clips. What it will be - the choice is yours. In the field wiring to install an external junction box and wire connections, wiring and installation of access points is carried out just as in flush mounting method. The advantage of an open installation is easy access to all the wiring, and the disadvantage - not too aesthetic.
