Using the 12 instead of the 6 AWG wire will ___ the amount of time required for a circuit breaker to open when a ground fault occurs. Select one: a. increase b. decrease c. have no effect on - Answer -increase Providing a low impedance ground return path ___ when a ground-fault occurs. Select one: a. has no effect on the circuit current b. permits a high current to flow c. limits the amount of current to a small amount - Answer -permits a high current to flow In a run of conduit, when couplings and connectors are loose this will ___ the amount of time required for a circuit breaker to open when a short-circuit occurs. Select one: a. have no effect on b. increase c. decrease - Answer -have no effect on The plans indicate that you should install a 300-amp branch circuit in Schedule 40 PVC with a 4 AWG equipment grounding conductor. However, you did not have any 4 AWG wire so you pulled in 10 AWG instead. With a load connected, the normal circuit current will be ___ with the 10 AWG EGC (compared to using a 4 AWG EGC). Select one: a. the same b. less c. greater - Answer -the same The primary purpose of grounding metal equipment enclosures and metal raceways to the grounding electrode system (earth) is to ___.I.
