Allied Moulded ALMSB-4 – Frequently Asked Questions

1) How many devices can the Allied Moulded SB-4 switch box hold?
Four. The SB-4 is a 4-gang box, so it takes four straight-blade devices (switches or receptacles) side by side in one enclosure, wired up behind a single four-gang plate.
2) What is the cubic inch volume of the SB-4 box for conductor fill calculations?
74.8 cubic inches of interior volume. That is the number you use when running an NEC box fill calculation for the conductors, devices, clamps and grounds going into the four gangs.
3) What are the overall dimensions of the Allied Moulded SB-4 four gang box?
7-5/8 x 3-3/4 x 3-9/16 inches overall. Lay that against your stud bay and rough opening before cutting: a four-gang opening plus the depth dimension has to clear any insulation, blocking or plumbing behind the wall.
4) Is the SB-4 a metal box or plastic?
Molded thermoplastic, not steel. It is non-conductive and corrosion resistant, which is why it is used for standard residential branch circuit work. Since the box itself is not a grounding path, every equipment ground has to be made up in the box and carried to the device.
5) Can I use the SB-4 in a remodel, or is it new construction only?
Both. Allied Moulded lists the SB-4 for new construction and renovation wiring where a multi-gang device box is required, and the adjustable depth is the feature that makes it workable on existing walls with unknown finish thickness.
6) Is the SB-4 suitable for a bank of four receptacles rather than switches?
Yes. Despite the switch box name, it is built for straight-blade device and receptacle installations, so a run of four duplex receptacles in one box is exactly the intended use. Just keep the conductor count inside the 74.8 cubic inch fill allowance.
7) What part number do I order for the Allied Moulded 4-gang Sliderbox?
SB-4 is the Allied Moulded manufacturer part number for the 4-gang adjustable thermoplastic switch box. The 2-, 3- and 5-gang Sliderbox sizes carry their own numbers, so confirm the gang count matches the device count on your plate.
