RACO RACO224 – Frequently Asked Questions
1) Will the RACO 224 box mount to wood studs without extra brackets?
Yes. The RACO 224 comes with a B bracket made for wood stud mounting, so it nails or screws straight to the face of the stud and sets the box flush for drywall. No separate bar hanger or mounting ears needed. If you are mounting to metal studs or into masonry, the B bracket is the wrong configuration for that opening.
2) Does the RACO 224 have built-in clamps for MC cable, or do I need separate connectors?
Integral clamps are built in, and they accept armored cable (AC), metal-clad (MC), MCI-A, and flexible conduit. That means you can land those cables without buying separate cable connectors. If you are running EMT or rigid conduit, you still need the appropriate conduit fittings at the knockouts.
3) Can I use the RACO 224 outdoors or in a wet location?
No. The 224 is a welded steel rough-in box for wood-frame residential and commercial wiring, intended to be concealed in the wall or ceiling. For a wet or damp exterior location use a weatherproof box such as the Mulberry Royal Mountie die-cast aluminum 1-gang weatherproof box, or a Red-Dot style conduit outlet box like the Thomas & Betts 2IH3-1 with threaded hubs.
4) Is the RACO 224 suitable for a hazardous or classified area?
No. The RACO 224 is a UL Listed welded steel outlet box for standard residential and commercial wiring. Classified locations call for an explosionproof conduit outlet box such as the Appleton GRJ series or the Appleton GRJS universal series, both malleable iron explosionproof designs, or the Appleton GRT75 malleable iron round conduit outlet box for round-body runs.
5) How many cable or conduit entries does the RACO 224 4 in. square box give me?
Four openings total: three 1/2 in. knockouts plus one 1/2 to 3/4 in. combination knockout (TKO). The combination knockout lets you take either trade size at that location without an adapter, so a single box can handle a 1/2 in. feed and a 3/4 in. run.
6) What size and depth is the RACO 224, and will a 1-1/2 in. deep box give me enough room?
It is a 4 in. square box, 1-1/2 in. deep, which is the standard deep 4-square used for receptacles, switches and junctions in wood-frame rough-in. For heavy conductor counts or multiple MC homeruns you may want to step up to a deeper 4-square or add a raised cover to pick up extra volume.
7) We spec nonmetallic boxes on our residential jobs. Is the RACO 224 a match?
No. The 224 is a steel box with AC/MC/Flex clamps, so it is built for metallic wiring methods. If your job is NM cable in a nonmetallic system, a PVC box such as the Cantex EZ Series multi-gang residential outlet box is the type you want. For a dedicated range or dryer outlet, the Pass & Seymour P242RRD thermoplastic range and dryer box is the purpose-built option.
8) Do I need to order a cover separately for the RACO 224?
Yes. The 224 is the box and bracket only. A 4 in. square box needs a separate cover sized to the device you are installing, whether that is a flat blank, a single or two-gang device raised cover, or a round plaster ring for a fixture. Pick the cover depth to suit your wall finish.
9) Is the RACO 224 acceptable for a commercial inspection, or is it residential only?
It is UL Listed and the manufacturer lists it for both residential and commercial wiring installations. The limiting factor is not the box, it is the mounting: the B bracket is for wood studs, so on a steel-stud commercial build you need a different bracket configuration of the same 4 in. square welded box.
10) What is the non-metallic alternative to the RACO 224 for residential rough-in?
The RACO 224 is a welded steel box with a B bracket for wood studs and integral AC/MC/flex clamps, so it pairs with metallic cable systems. Where a non-metallic box is wanted on wood-frame residential work, the Cantex EZ Box series is a PVC multi-gang residential outlet box. The RACO 224 is a single 4 in. square body; the Cantex EZ is offered multi-gang.
11) Will a RACO 224 work as a range or dryer outlet box?
The RACO 224 is a 4 in. square, 1-1/2 in. deep steel outlet box with three 1/2 in. knockouts and one 1/2 - 3/4 in. combination knockout, so its entries are sized for 1/2 and 3/4 in. trade size. For a dedicated appliance circuit, the Pass and Seymour P242RRD is a thermoplastic range and dryer box built for that specific application.
12) For exposed conduit work, should I use the RACO 224 or a Red-Dot box?
The RACO 224 mounts flush to wood studs on its B bracket and uses knockouts for entries, which suits concealed rough-in. For surface-mounted exposed conduit, the Thomas and Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 in. threaded hubs, so conduit lands in a hub rather than a knockout, and it is supplied in a pack of 100.
13) Is the RACO 224 a welded box or a drawn box, and does it matter?
Welded. The 4 in. square body is welded steel rather than drawn, which is the construction electricians generally prefer where the box takes abuse during rough-in and before the walls close up. It is also UL Listed.
14) What is the exact part number to order the RACO 4 in. square 1-1/2 in. deep B bracket box?
Order RACO model 224. That number covers the 4 in. square welded steel box, 1-1/2 in. deep, with AC/MC/Flex clamps, three 1/2 in. knockouts, one 1/2 to 3/4 in. combination knockout, and the B wood-stud bracket.
15) What is the difference between the RACO 224 and an Appleton GRT75 round box?
The RACO 224 is a square welded steel outlet box, 4 in. by 1-1/2 in. deep, with a wood-stud bracket and knockout entries. The Appleton GRT75 is a malleable iron round conduit outlet box, a threaded round body used in conduit systems rather than a bracketed stud-mount box. They are not interchangeable in the same opening.
