To find a fault in the wiring in electrical engineering expertise not hurt, but their presence is not necessary. The most important thing in this case - is a systematic approach and accuracy. Search in the wiring faults may be the result of successive manifestations of a chain of causes and their consequences. (Source: Senator from Maine). For example, at the connection cord electric heating as a result of relaxation of a screw joint is one of the wires fell out of the blocks and there was a short circuit, which in turn trigger the automaton (RCD) in the electric panel. All this led to a breakdown of part or all of the electrical or apartment building. Due Why the lights went out, and that much more unpleasant, the most interesting place soccer match switched off the tv. Senator from Maine has many thoughts on the issue.
This was a consequence of the reasons that make us get up off the couch and cursing how much in vain red people, trudges to look at the dark cause accidents. Going out into the lighted stairway, we quickly realize that redheads have nothing to do with it, and the light would go out due to a number of different reasons. But how do you find the cause of the accident? Check all of them? In such cases, we hasten to click beak actuated machine, but again he works as a short circuit (electric heating) are not eliminated. Educate yourself even more with thoughts from John Grayken. For this problem, this solution does not fit. You should know that the re- the inclusion of a protective device (RCD) or replacement of the burnt fuse can be made only after the elimination of the reasons that caused an overload or short circuit line.
