Carlon B108B-UPC – Frequently Asked Questions

1) What size Carlon blue PVC box do I need for a single switch or receptacle?
Carlon's blue PVC single-gang boxes run from 8 cubic inches up to 24.5 cubic inches, so the choice comes down to how many conductors land in the box. The 8 cu in B108B-UPC comes with a bracket, the B118A is a plain 18 cu in box, the B120A-UPC is 20 cu in with nails, and the B125AB is 24.5 cu in with a flange. For a device box with several cables entering, go to the 18 or 20 cu in size rather than the 8.
2) Can I use a Carlon blue PVC junction box with Romex / NM cable?
That is exactly what these are for. The Carlon blue PVC boxes are designed and listed for use with non-metallic sheathed cable in accordance with Article 314. The blue color is the trade's visual shorthand for a non-metallic new-work box on the job site. They are not intended for metal-clad or armored cable work, which uses metallic boxes with the appropriate connectors.
3) What is the difference between the nail-on, bracket, and flange versions of the Carlon blue box?
Three different ways of hanging the box on framing. The nail versions (B120A-UPC, B344AR-UPC, B418AR-UPC) and the captive-nail B232ACP drive straight into the side of a stud, which is the fastest method on open stud walls. The bracket versions (B108B-UPC, and the extended-bracket B455AH) mount off a bracket that sets the box face against the stud edge. The flange versions (B125AB, B232BR, B344AB) use a mounting flange instead. All of them are new-work boxes for stud framing, not old-work boxes that clamp to finished drywall.
4) How many gangs do Carlon blue PVC boxes come in?
One, two, three, and four gang. Volume climbs with the gang count: 8 to 24.5 cubic inches at one gang, 32 cubic inches at two gang (B232ACP and B232BR), 44 cubic inches at three gang (B344AB and B344AR-UPC), and 54 to 60 cubic inches at four gang (B418AR-UPC at 54, B455AH at 60). Pick the gang count off the device count in the wall plate, then confirm the cubic inches cover your conductor fill.
5) What is the largest Carlon blue PVC box available, and what would I use it for?
The B455AH is the largest at 60 cubic inches, four gang, with an extended bracket. That is the one for a four-device ganged assembly where the box also serves as a splice point and the conductor count pushes fill limits. The next size down at four gang is the 54 cubic inch B418AR-UPC, which mounts with nails instead.
6) Will a PVC box hold up in a damp basement or garage wall?
PVC is the reason a lot of contractors choose these over steel in those spots. The blue PVC body resists moisture and corrosion, so it does not rust the way a steel box does in a humid basement, garage, or utility room. Two things to hold to: they are listed for use with non-metallic sheathed cable under Article 314, and PVC boxes do not bond to ground the way a metallic box does, so your equipment grounding conductor has to land on the device or a ground screw, not on the box.
7) Which Carlon blue box should a contractor buy for a large rough-in job versus a single repair?
Packaging differs by variant. The B232ACP two-gang 32 cubic inch box is a contract pack, meant for volume rough-in work. Several others (B108B-UPC, B120A-UPC, B344AR-UPC, B418AR-UPC) are retail packs, which suit a truck stock or a one-off replacement. The electrical content is the same box either way; the difference is how it is packed.
8) Are Carlon blue PVC electrical boxes made in the USA?
Yes, the Carlon blue PVC boxes are manufactured in the United States, under the Carlon / Nutek brand label. That matters on public and institutional jobs where domestic sourcing is a spec line.
