Since the flat light sources areact as chandeliers and lamps as well as wall sconces and table lamps, when their failure to perform necessary repairs of switches and sockets. After all, most of the lighting failure are reduced to the problems associated with contact closure. In this case, you must perform repair outlets with their own hands.
Before repairing electrical wiring,should be in the apartment or house to turn off the voltage. After that you should make a complete absence of electrical current (it can be a simple display with a screwdriver). Only now you can begin to work.
Start with checking outlets
Sockets are most subjected to breakages. One reason - excessive load. If one outlet comprise several home appliances, especially with high power, the probability of breakage is significantly increased.
Failure of the socket, the first thingshould pay attention - whether it is applied to it electricity. To perform such a check is necessary to remove the front panel socket and check the voltage at the terminals (in places of forks and plates connections). A suitable tool for this will be the voltage indicator with two poles, through which you can check out a phase and zero. For these purposes, you can use the digital multimer or old analogue, known as "tseshka".
If the contact plates show voltagethen the problem lies in the absence of the socket contact and plug the appliance (this is typical of the problem for the majority of old domestic outlets in the design of which can not accommodate the springs). All that now you need - with the help of pliers to shake contact sockets. But for this step, you need to disconnect power.
This solution will be effective only whenSocket is not experiencing heavy loads. Otherwise, the situation could be repeated, the only question is when. So do not skimp on the new socket - replacing the old is the best option.
In the case where the socket contacts are notvoltage, you need to check its presence at terminals. After you remove the stress, you need to let go of attachment socket and remove it from the mounting box. Maybe just fell out of the terminal wire or because a large amount of current and weak contact on it appeared a deposit, which prevents the flow of electricity good. To resolve this problem you just need a good tighten the screws on the terminals.
The problem may be in the junction box
If the screws are tightened on the terminals,wire fracture is not visible, and the power to the outlet does not arrive, then the cause of the problem, most likely lies in the junction box. Most often, they are located above the socket in the wall a little bit below the ceiling. The most widespread electrical circuit in which the power supply in the room is directed first to the junction box, and then later to the outlets, lighting fixtures, switches, etc.
After you remove the distributionbox lid Carefully inspect wires in case of fractures, bends and assess the integrity of the insulation. In cases where the wires lay exposed to heat, the insulation is brittle and fragile. Remove twists with all insulation and tighten them with pliers - maybe outlet does not work because of bad contacts in the box.
If visible signs of heating and fractureswires are not observed, check whether it comes to the power box. To do this, you need to install on any terminal or twisting a voltage is applied.
Supply stranding determined visually - theyactivated increasing the number of wires (especially if you post for many years, whereas the outlet, and lighting are connected to the same group). In modern wiring sockets and lighting, as a rule, divided into groups, so look for a fault during the repair much easier, because each group has its own section of the wire.
Wire break in the wall
In the case where the supply voltage for thesocket in the junction box is present, but in the current outlet terminal does not come, then the cause of failure, one - in the wall there was a broken wire. He could be interrupted during repair or wiring can not be made the most qualitative way, and sometimes come across and a faulty wire.
All that now remains - just replace the faulty lead or stretch it from the nearest box or outlet.
If the supply voltage is no outlet,then the cause of the problem is before the box - in a cabinet. Try to measure the voltage on the traffic or machines, also check the wiring, maybe they broke. If the voltage at the other junction box is present, then you can connect to it.
As seen repair outlets with their own hands a relatively simple process. However, you must have a working knowledge of it. If you lack them, then repair their own hands - not a place for experiments, this is a very dangerous job. If you feel even a fraction of uncertainty - it is better to seek help from professionals.
