Selection of the protection system of the electrical installation is fundamental both to guarantee correct economical and functional service of the whole installation and to reduce the problems caused by abnormal service conditions or actual faults to a minimum.

The earth fault, caused by an insulation loss between a live conductor and an exposed conductive part, represents a plant engineering problem that may cause damage to the electrical installations and above all may jeopardize people; as a matter of fact, people could get in touch with an exposed-conductive-part not normally live but which, due to the fault, might have a dangerous potential to ground. Therefore, the solution against this fault is a circuit breaker.
