Thomas & Betts 4-SDW-FB-SPL – Frequently Asked Questions
1) How many conductors can I put in the Thomas & Betts 4-SDW-FB-SPL square box?
The box holds 31.9 cubic inches, which is what you use for NEC box fill math. At 2.00 cubic inches per 14 AWG conductor that works out to 15 conductors, and at 2.25 cubic inches per 12 AWG it works out to 14, before you deduct for devices, clamps, and grounds. Remember a device yoke counts as two conductor volumes and all grounds together count as one.
2) What size knockouts does the 4-SDW-FB-SPL welded square box have?
It has combination 1/2 and 3/4 inch end knockouts, 13 of them in total, so you can land either trade size of connector without an adapter. That count gives you room to bring in several circuits plus a switch leg on the same box.
3) Is the 4-SDW-FB-SPL box UL listed?
Yes. The box carries UL file E2969.
4) Does the 4-SDW-FB-SPL come with a cover or a mud ring?
No. It's the box only, sold each. A flat blank cover or a raised device ring (single or two gang, in the depth that matches your wall finish) is a separate order, and the ring's own cubic inch capacity adds to the 31.9 of the box for fill purposes.
