Question

Quizplus · Accepted Answer

Isolation switching involves cutting off the electrical supply to ensure the safety of those working on the equipment. Basic protection refers to the protection provided by basic insulation, double insulation or reinforced insulation. Fault protection refers to protective devices that trip or isolate a circuit in the event of an over-current, short circuit or earth fault. Equipotential bonding involves connecting all metal parts that can be touched to a common earth or grounding point to ensure they are at the same potential to reduce the risk of electric shock.
