Thomas & Betts CWXV-25 – Frequently Asked Questions
1) What size is the Thomas & Betts CWXV-25 switch box and how much wire fill does it allow?
The CWXV-25 is a 3 x 2 x 2-3/4 inch steel switch box with 14 cubic inches of volume. That 14 cu. in. figure is what you use for box fill calculations, so it suits a single device with a modest number of conductors. If you need more room in the same single-gang footprint, the Allied Moulded P-181 FlexBox is an 18 cu. in. one-gang switch/receptacle box.
2) Does the CWXV-25 come with a mounting bracket, or do I need to buy one?
A bracket is part of the box. The CWXV-25 ships as a bracketed switch box, so it nails or screws directly to a stud face for new-construction rough-in rather than needing a separate box-mounting bracket or support.
3) What is the closest gangable steel switch box equivalent to the Thomas & Betts CWXV-25?
The RACO 517 TIGER GRIP gangable steel switch box is the nearest like-for-like alternative: both are gangable steel switch boxes. The CWXV-25 is a 3 x 2 x 2-3/4 in. box with 14 cubic inches of volume and a mounting bracket, while the RACO 517 is sold as an old work box for cutting into finished walls rather than bracket-mounting to a stud.
4) I need a deeper gangable switch box than the CWXV-25 for several conductors - what should I use?
The CWXV-25 is 2-3/4 in. deep with 14 cubic inches of usable volume, which fills up quickly once you have multiple cables and a device. If your stud bay allows it, the RACO 518S is a gangable switch box 2-1/2 in. deep that comes with a STAB-IT connector built in; for a larger non-metallic option, the Allied Moulded P-181 FlexBox 1-gang switch/receptacle box offers 18 cubic inches. Match the box fill to the conductor count in the opening.
5) Can I use a non-metallic box instead of the Thomas & Betts CWXV-25?
Only if the wiring method and the opening allow it. The CWXV-25 is a steel switch box, which suits metal raceway and armored cable where the box itself carries the equipment ground. If you are running NM cable in wood framing, the Allied Moulded P-181 FlexBox 1-gang thermoplastic residential switch/receptacle box at 18 cubic inches is a non-metallic alternative; the Allied Moulded 2302-NKV is a fiberglass reinforced 2-gang switch box if you need two devices. Neither is gangable the way the steel CWXV-25 is.
6) What switch box should I use in metal stud partitions instead of the CWXV-25?
The CWXV-25 is a bracket-mount gangable steel box, and its bracket is intended for fastening to framing rather than clipping to a steel stud. For light-gauge steel stud walls, the Cantex EZ20SB EZ Box is a 1-gang non-metallic box made specifically for steel studs. If you need the box itself to be metal in that wall, the Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is a 1-gang gangable switch box in pre-galvanized steel with an adjustable body for setting depth to the finished surface.
7) Is this box for new construction or for cutting into an existing finished wall?
New work. The bracket on the CWXV-25 mounts to exposed framing, which means the wall has to be open. For retrofitting into finished drywall, a gangable old-work box like the RACO 517 TIGER GRIP is the right type, since it clamps to the wallboard instead of the stud.
8) Is the Thomas & Betts CWXV-25 switch box UL listed?
Yes, the CWXV-25 carries UL file E2969. That matters on inspected commercial and multi-family work where every box in the wall has to be a listed device box.
9) I need a two-gang switch box - can I gang the CWXV-25 or should I buy a 2-gang box?
The CWXV-25 is gangable, so two of them can be joined to serve two devices in one opening. If you would rather set a single factory two-gang box, the Allied Moulded 2302-NKV is a fiberglass reinforced 2-gang electrical switch box. The tradeoff is material and ground path: the CWXV-25 is steel, the 2302-NKV is non-metallic.
10) How does the Thomas & Betts CWXV-25 differ from the Steel City Adjust-A-Box LXWOWC-25?
Both are Thomas & Betts 1-gang gangable steel switch boxes, so they gang together for multi-device openings. The CWXV-25 measures 3 x 2 x 2-3/4 in. with 14 cubic inches of volume and ships with a mounting bracket. The LXWOWC-25 is the Steel City Adjust-A-Box in pre-galvanized steel, with an adjustable body so the front of the box can be repositioned relative to the finished wall after rough-in.
11) Is the RACO 517 a drop-in replacement for the CWXV-25 on new construction?
Not directly. The RACO 517 TIGER GRIP is a gangable steel switch box configured for old work, meaning it is retained in a cut opening in existing finished wall. The CWXV-25 is a 3 x 2 x 2-3/4 in. gangable steel box supplied with a mounting bracket for fastening during rough-in, before the wall covering goes on. Use the CWXV-25 where you still have open framing and the 517 where the drywall is already up.
12) Which switch box includes a cable connector so I do not have to buy clamps separately?
The RACO 518S is a gangable switch box 2-1/2 in. deep supplied with a STAB-IT Series connector, so the cable termination is built into the box. The Thomas & Betts CWXV-25 is a 3 x 2 x 2-3/4 in. gangable steel box with a mounting bracket, so plan your cable clamping or connectors according to the wiring method you are running into it.
13) Will a steel switch box like this work in a metal stud wall?
The CWXV-25 is a bracketed steel box intended for fastening to framing, and steel boxes are routinely screwed to metal studs. If you want a box engineered specifically for steel studs with a dedicated stud attachment, the Cantex EZ20SB EZ Box is a non-metallic 1-gang steel stud box.
14) How is the CWXV-25 sold, individually or by the carton?
The selling unit for the CWXV-25 is each, so you can order the exact count a job needs rather than a full carton.
15) What finish does the CWXV-25 box have, and will it match other steel boxes on the job?
It is a steel box with a silver (plain galvanized-look) finish, which is the standard appearance for metallic device boxes and will blend with the rest of a steel-box rough-in. Boxes are buried in the wall anyway, so finish is about corrosion protection, not looks.
