All electrical equipment and installations need to be safe for users and the same systems. Electricity conductors need to be insulator from each other, so as not to create danger or unnecessary consumption. A poorly insulated circuit can create leakage currents that can be dangerous and trigger your GFCI, RCCB or ELCB. Each country regulates these levels, where isolation is acceptable. Check the continuity of the cables, circuit connections, contact closure, the so-called "circuit breakers", fuses, connection resistance of the connections etc. are very important measures.
