ICC Residential Electrical Inspector Level 1 (E1) Practice Test

In a feeder arrangement, what is the role of the grounded conductor?

To carry return current To bond to the grounding electrode To carry fault current to ground To shield the circuit

Correct Answer:

To carry return current

Explanation:

The grounded conductor provides the return path for current in normal operation, completing the circuit. Current leaves the source on the hot conductors and returns on the neutral, so the neutral carries the load current back to the source. It isn’t meant to carry fault current to ground (that’s the function of the equipment grounding conductor and the grounding system), nor is it used to shield the circuit. Bonding to the grounding electrode happens at the service equipment, while the neutral is typically kept separate from the grounding path in a feeder. So carrying return current is the best fit for its role.
