Carlon B455A-UPC – Frequently Asked Questions

1) How many wires can I get into a 60 cubic inch 4-gang box?
The Thomas & Betts B455A-UPC gives you 60 cubic inches of box volume across four gangs. Under NEC box fill rules you divide that volume by the cubic-inch allowance for the largest conductor in the box, so at 2.25 cu in per 14 AWG conductor a 60 cu in box allows 26 conductor equivalents, and at 2.00 cu in per 12 AWG it allows 30. Remember that each device yoke counts as two conductors and all grounds together count as one, so a fully loaded four-device box eats a meaningful share of that before the circuit conductors go in.
2) Is this a new-work box for stud framing or a remodel box for existing drywall?
The B455A-UPC is a nonmetallic box fastened with mounting hardware at the framing before the wall is closed, per the install sequence: set the box, secure it, then route cable through the entry points and install devices. If you are cutting into finished drywall with no stud access, you want an old-work box with wing clamps instead, not this one.
3) Can I use a PVC electrical box in a damp or corrosive area instead of a steel box?
PVC is the reason to pick this one. The B455A-UPC is molded PVC rather than steel, so it does not rust and holds up where moisture or corrosive atmosphere would eat a metal box, which is why these turn up in plants, wash-down adjacent areas, and below-grade rooms. PVC is also nonconductive, so there is no box bonding requirement the way there is with a metallic box, though every device ground still has to be made up properly.
4) Does this 4-gang box come with a cover plate or device screws?
The B455A-UPC is sold as a box, one each, not as a kit. Plan on ordering the four-gang wall plate separately and matching it to what you are mounting, since a four-gang plate has to be configured for the mix of toggles, decorator devices, or receptacles you install. Device mounting screws are typically supplied with the devices themselves.
5) Will a 4-gang box work for a bank of switches at an entry, or should I use separate boxes?
A single four-gang box like the B455A-UPC puts four devices behind one plate at one framing location, which is the usual approach for a switch bank, a control station, or a cluster of outlets. Separate single-gang boxes only make sense when the devices land on different studs or feed circuits you want physically separated. The trade-off with four gangs is wire volume: you have 60 cubic inches to share among four device yokes plus all the circuit conductors and grounds, so count your fill before committing.
6) What is the exact part number for the Thomas & Betts 4-gang 60 cubic inch PVC box?
Order it as Thomas and Betts B455A-UPC. That is the four-gang, 60 cubic inch nonmetallic outlet box in blue PVC. Distributors will also see it under UPC 034481020615.
7) Why is this outlet box blue, and does the color mean anything?
Blue is the standard industry color for nonmetallic new-work outlet boxes, and the B455A-UPC follows it. The color is a trade convention, not a rating, so it has no bearing on where the box can be used. If a property manager is matching what is already in the walls, blue PVC boxes are what most residential and light commercial new construction uses.
