Which of the following would count as two conductors when computing box fill?

Question

Quizplus · Accepted Answer

When computing box fill, each wire and each device (such as a switch or receptacle) counts as one conductor. Therefore, a duplex receptacle with its two hot and two neutral wires counts as four conductors. A GFCI receptacle also has two hot and two neutral wires, so it counts as four conductors. A single-pole switch has only one wire connected to it, so it counts as one conductor. Therefore, the correct answer is D, since all of the above choices include at least two conductors.
