An effective Ground-Fault current path is? - ANSWER✔️💫-An effective Ground-Fault current paths 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 - ANSWER✔️💫-False. GFCI = ground-fault circuit
interrupter
Grounding and bonding means exactly the same thing? - ANSWER✔️💫-False. Bonding is a means of
allowing electrical continuity between metallic objects.
