         Every electrical apparatus and installation need to be safe for the user and for the equipment itself. Electrical conductors of electricity need to be insulated from each other, so that they do not create electrical hazard or unnecessary consumption.
         Badly insulated circuits can create leakage current which can be dangerous and trip your GFCI, RCCB or ELCB. Each couontry regulate those levels at which the insulation is acceptable. Generally, insulation resistance measurements are done between each conductor and the earth, and between each conductors.
         Checking the continuity of wires, complete circuits, connections, closure of contacts, circuit breakers, fuses, bonding resistance of connectinos, etc ... are all very important.
