Question 1 of 3

1. Question

What is required when ungrounded service entrance conductors are connected in parallel in two or more raceways or cables?

Grounded conductors, neutrals, must also be installed in each raceway or cable and connected in parallel.
Correct Incorrect Correct answer

Grounded conductors are not required to be installed if the conductors are aluminum.
Correct Incorrect Correct answer

Only one raceway or cable needs to have grounded conductors connected in parallel.
Correct Incorrect Correct answer

Each raceway or cable must have its own separate grounding electrode system.

2. Question

Why do we install grounded conductors (neutrals) in each raceway or cable when running conductors in parallel?

To prevent inductive heating by canceling out magnetic fields.
Correct Incorrect Correct answer

To make the wires look neat and organized.
Correct Incorrect Correct answer

To increase the overall power of the circuit.
Correct Incorrect Correct answer

To save on the cost of using more conductors.
