Electric Fault
Perhaps the problem is with a mechanical (drilling walls, installing baseboards, etc.). Then look at the electrical panel and make sure that all automatic device (RCD), leading to the apartment included. For troubleshooting, you can use one of the above mentioned electric devices: tester, voltmeter, ac current, a screwdriver-phase indicator or probe consisting of an electric bulb screwed into the cartridge which are connected two pieces of wire in vinyl insulation. Knowing how to go, the wiring in the apartment and seeing the consequences of malfunction, you can begin to search for the most trouble. If when the machine is off all the lights in the apartment, it means that a fault in either electric panel, either in the first raspayachnoy box. Open electrical panel and check the tester or test lamp comes on whether this group the presence of voltage (phase). For better visibility, we use the control lamp (it is lit or unlit). Check the voltage it is necessary after breaker.
To that end, a measurement of the incoming and exhaust from the circuit-breaker voltage relative to the working of the zero clamp (tire). If the input terminals are present, all three phases, and on weekends there is no one or all three, then, after turning off the introductory switchgear and verifying the absence of voltage input terminals of the protection device, proceed to removing and replacing a known working device (RCD). If the fault is not in the electric panel, you should check the first box of flap. Typically, a fault be discovered. If it does not do voltage, hence, on the road is broken (which rarely happens). Lack of lighting in a room can be caused by a malfunction of the fixture (chandelier lamp) or a switch.
With control light or tester should be when the switch contact to verify the incoming voltage to the lighting fixture and switch. Most probably lies in these compounds. If the apartment is not working part of the socket, then stress in the Female group served, and the fault can be in non-performing outlets and a running outlet (power comes from it). Troubleshooting should start with a working outlet. Check the voltage on her way to first deal with two incoming wires, and then the two wires (phase and zero) of the outgoing wires. Contact between the wires can be oxidized and the electric current through that contact can not be held. Need to clean up the wires and re-tighten the contacts in the socket.
