Box calculations for 4 AWG and larger conductors (under 600 volts) are performed based on the ____.
A) volume of the box
B) size and number of raceways
C) number of rings and the volume of the box
D) branch circuit load

Question

Quizplus · Accepted Answer

Box calculations for 4 AWG and larger conductors (under 600 volts) are based on the size and number of raceways. This is because the raceways that contain the conductors determine the amount of space needed in the box. The volume of the box and branch circuit load are not the primary factors considered in these calculations. The number of rings and the volume of the box are also not factors in determining box size for these conductors.
