To determine the total box volume required for a box with two 12 AWG conductors entering and leaving, how many conductors need to be counted?

To determine the total box volume required for a box containing conductors, the National Electrical Code (NEC) specifies that each conductor entering and exiting a box must be counted, along with additional conductors for any connections. In this scenario, you have two 12 AWG conductors entering and two that are leaving the box.

First, the two conductors that are entering the box are counted, and then the two conductors that are leaving the box are also counted. This gives a total of four conductors. However, the code also requires you to account for the fill space within the box itself.

In addition to just the enter/exit conductors, you also need to consider additional conductors for any splices, tap connections, or equipment grounding conductors that may be introduced in the box. For the specifics of this question, the total comes to five (two entering + two leaving + one for a potential connection).

However, if there is a requirement or a norm in your study context which states that an additional connection point or equipment ground needs to be included, that could lead to counting another conductor, thus totaling six. The final consideration of '7' conductors would typically include an added buffer for comprehensive calculations or hypothetical
