Typically, the wiring (copper wire) initially has a long service life and therefore never by itself does not terminate and does not close. 60 per cent of all faults in the wiring occur at the joints wires between them. These places may include: Raspayachnye boxes; switchboards (joining the wires to the circuit breaker to the neutral bus); Switches (place sample sconces and chandeliers); Connect the wires in the sockets (sockets go train) Faulty wiring can cause a mechanical action in the field drilling, chiselling walls, installing baseboards, sample paintings, chandeliers and other things that can affect the defective wiring. In 20 percent of Electrical malfunction occurs due to circuit or an open electrical wiring in the wall panels. This is due to the large electrical load.

If the protective device (RCD) in order, and is chosen correctly, the machine needs to limit the load of electric networks by means of his trip. Closure or open supply may also be associated with crumbling, old aluminum wires, or you simply banal filled neighbors. Typically, this type of fault can be associated with poor wiring, which could work on "Hill electricians. Has been traced in a damaged or not Certified wire, were made without wiring boxes, poor attachment of wires. This is the most difficult type of failure, since Linked to chiselling walls, ceilings, etc. After removing this failures have something to cover up, repaint or paste, ie, wasting time and money on redecorating. Initially, to determine fault in the electrical, you need to visually examine the presence of darkening and deposits in the sockets, switches, chandeliers.
