The weakest link in the circuit designed to melt when an over-current flows is one definition of:
A) fault protection
B) a circuit protective conductor
C) a fuse
D) a consumer unit.

Question

Quizplus · Accepted Answer

A fuse is designed to melt and break the circuit when an over-current flows. This provides fault protection to the circuit and prevents damage or danger. A circuit protective conductor (CPC) is a separate wire used to protect against electric shock and is not typically associated with over-current protection. A consumer unit is an electrical distribution board that contains circuit breakers or fuses and other components used to control and protect electrical installations. Therefore, the most appropriate choice is C) a fuse.
