Determine the adequacy of the device box illustrated in below figure, where two standard sized 3 in. x 2 in. x 3.5 in. device boxes have been ganged to form a single box. Solution: Table . Installing safe, orderly electrical boxes and cables is made easy by following the recommended electrical codes.
Each single gang device yoke (regardless of the ampere rating of the device) counts as two conductor volumes, based on the largest conductor that terminates on the device. Boxes containing 6 AWG and smaller conductors must be sized in an approved manner to provide free space for all conductors, devices, and fittings. In no case can the volume of the box, as calculated in Sec. 314.16 (A), . For the smallest "with respect to depth" boxes, look away from single-gang as a box format; instead, look to a 4x4x1.5 with an appropriate cover plate to mount your device yoke . What’s the minimum box volume needed? Step 1. Count the conductors: Step 2. The volume factor for 14-ga. wire is 2 cu. in., so: Single-gang boxes come in three sizes, 18 cu. in., 20.4 cu. in. and 22.5 cu. in. Although .
