Question

If a box can hold eight No. 12 conductors and contains a cable clamp, a switch, and a looped conductor that is 13" (330 mm) long, the final number of No. 12 conductors allowed in this box is -------

Answer 1

The final number of No. 12 conductors allowed in this box is 5.

Step-by-step explanation:

The final number of No. 12 conductors allowed in this box would be 5. Here's how we can arrive at this answer:

1. The box can hold 8 No. 12 conductors.
2. However, the box already contains a cable clamp, a switch, and a looped conductor.
3. These items take up space that could otherwise be used for conductors.
4. Since the looped conductor is 13 inches (330 mm) long, it occupies more space than a No. 12 conductor.
5. We need to calculate how many No. 12 conductors can fit in the remaining space.
6. Let's assume the looped conductor takes up the same space as 3 No. 12 conductors.
7. Therefore, we subtract the space occupied by the looped conductor from the total available space in the box.
8. This leaves us with 8 - 3 = 5 No. 12 conductors that can fit in the box.
