devices currently in place.Correct Answer: D) A path intentionally constructed to facilitate the operation of the overcurrent protective devices currently in place.

• GFCI is never sensitive to small "leaks" of current.
• True. GFCI is designed only for major short circuits.
• True. Small leaks are handled by standard circuit breakers.
• False. GFCI = ground-fault circuit interrupter.
• False. GFCI only protects against power surges.

Correct Answer: C) False. GFCI = ground-fault circuit interrupter.

• Grounding and bonding means exactly the same thing.
• True. Both terms refer to returning current to the main breaker.
• False. Bonding is a means of allowing electrical continuity between metallic objects.
• False. Grounding is only used for temporary construction circuits.
• False. Bonding is exclusively for telecommunications wiring.

Correct Answer: B) False. Bonding is a means of allowing electrical continuity between metallic objects.
