Question

Where NMSC conductors pass through the walls of an outlet box, the following precautions must be made:

A) conductor insulation must be protected from injury
B) no strain must be placed on terminal connections
C) after the conductors are in place, there can be no openings larger than 6.75mm remaining in the connector.
D) all of the above
E) only A and C apply

Answer 1

The correct answer is D) all of the above, because NMSC conductors require insulation protection, no strain on connections, and no large openings after installation for safety.

Step-by-step explanation:

Where Nonmetallic-Sheathed Cable (NMSC) conductors pass through the walls of an outlet box, the following precautions must be taken: conductor insulation must be protected from injury, no strain must be placed on terminal connections, and after the conductors are in place, there can be no openings larger than 6.75mm remaining in the connector. Therefore, the correct answer to the question is D) all of the above. These precautions ensure electrical safety, protecting against both shock and thermal hazards. It's important to follow proper color-coding for wire insulation to identify live/hot, neutral, and ground wires, noting that the color codes can vary by region.
