Centaur PSB118-B – Frequently Asked Questions

1) What size device box do I need for a single switch versus two switches in new construction?
The Centaur plastic switch boxes come in a 1-gang version at 18 cubic inches and a 2-gang version at 32 cubic inches. One switch or receptacle goes in the 1-gang; two devices side by side need the 2-gang. Both carry a pre-attached bracket for fastening to a stud.
2) Can these bracketed plastic switch boxes be used in an existing finished wall?
No. Centaur's bracketed plastic switch boxes are new construction boxes, meant to be nailed or screwed to an exposed stud before drywall goes up. For an existing finished wall you want an old-work (remount) box with wing clamps that grips the drywall instead.
3) What is the cutout width I should plan for with the 2-gang Centaur plastic box?
The 2-gang PSB232-B measures 3.75 inches by 4 inches, versus 2.38 inches wide on the 1-gang PSB118-B at the same 3.75 inch length. Plan your drywall cutout to the 4 inch dimension on the 2-gang so a standard two-device plate covers the opening.
4) Are the Centaur PSB switch boxes sold individually or in a carton?
They ship in packs of 50, which is how electricians and builders buy them for a full rough-in. Order the 1-gang/18 cu in or the 2-gang/32 cu in as separate items.
5) Will 18 cubic inches be enough for a switch with two cables entering the box?
18 cubic inches is the capacity of the 1-gang Centaur box, which covers a typical single-device rough-in with a feed and a switch leg. If your box is a junction point with three or more cables plus a device, step up to the 32 cubic inch 2-gang and run your box fill calculation against that larger figure.
6) What does the B bracket on these Centaur boxes do?
The bracket is pre-attached to the box and sets the box against the face of the stud at the right depth, so you fasten once and the box is already aligned. It saves setting depth by eye on every opening across a rough-in.
7) Do I still need a ground screw or bonding jumper with a plastic switch box?
The box body itself is plastic, so it is non-conductive and does not need bonding the way a steel box does. Your equipment grounding conductor lands on the device's green screw, and any additional grounds are joined in the box.
8) Are these boxes suitable for commercial work or residential only?
Both. Centaur lists these plastic bracketed switch boxes for residential and commercial device mounting in standard wall construction, which covers multi-family, light commercial fit-outs and tract housing alike.
