6. Why Test is Necessary?
INSULATION
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 country regulates these levels at which the insulation is acceptable.
Generally, insulation resistance measurements are done between each
conductor and the earth, and between each conductors.
CONTINUITY
Checking the continuity of wires, complete circuits, connections, closure of
contacts, circuit breakers, fuses, bounding resistance of connections, etc...
are all very important.
