Centaur PSB108-FB – Frequently Asked Questions

1) Is the Centaur PSB108-FB switch box for new construction or remodel work?
New construction. The PSB108-FB has an integrated FB bracket that nails or screws to the face of an exposed stud before the drywall goes up. For a remodel where the wall is already closed, you need an old-work (remodel) box with ears or wing clamps instead, because the bracket on this one has no stud to land on.
2) What are the dimensions of the Centaur PSB108-FB plastic switch box?
It measures 3.625 inches in height and length, 2.25 inches in width, and 1.25 inches deep. That 1.25 inch depth is the number that matters most: it is a shallow box, so it fits furred-out walls and tight stud cavities, but it will not swallow a deep dimmer or a smart switch with a large body.
3) Can I use this plastic switch box in a commercial building?
The PSB108-FB is intended for residential and light commercial use in standard wall construction. For heavier commercial work with conduit, a metallic box is the usual call, since non-metallic boxes are built for cable systems rather than threaded raceway.
4) How many boxes come in a pack of the Centaur PSB108-FB?
The PSB108-FB plastic switch box is sold in quantities of 25, which is how electricians rough-in a floor or a unit at a time. Each box weighs 0.12 lbs, so a 25-pack is light enough to carry up a ladder.
