How many conductors total are being used if two are entering, two are exiting, and there is one equipment grounding conductor connected to the box?

To determine the total number of conductors being used, you need to account for all the conductors entering, exiting, and grounded to the box.

In this scenario, there are two conductors entering the box. These could be either hot or neutral wires, depending on the application. Additionally, two conductors are exiting the box, which also may represent hot or neutral wires going to another device or location.

Along with these conductors, there is also one equipment grounding conductor. The purpose of this grounding conductor is to provide a safe path for fault current, enhancing the safety of the electrical system.

By summing these up:

• 2 conductors entering the box

• 2 conductors exiting the box

• 1 equipment grounding conductor

Adding these together gives a total of 5 conductors (2 + 2 + 1 = 5).

It's vital to understand that if the answer provided as C (7) was assumed to be correct, it seems there may have been a misunderstanding in counting or recognizing additional conductors that were not listed in the scenario. Thus, based on the details provided, the correct count of conductors utilized is indeed 5.
