B) circuit breaker
C) fuse
D) GFCI

Question

Quizplus · Accepted Answer

A device that monitors the current flow on both the ungrounded "hot" conductor and the grounded conductor is a ground fault circuit interrupter (GFCI). It is designed to quickly shut off power when it detects an imbalance between the two currents, which could indicate a dangerous ground fault. TVSS (transient voltage surge suppressor) protects against voltage spikes and surges, circuit breakers protect against overcurrent, and fuses protect against overloading.
