RACO RACO953 – Frequently Asked Questions
1) Will the RACO 953 outlet box hold four devices side by side, like switches or receptacles?
Yes. The RACO 953 is a welded 4-gang steel box sized to take four devices mounted side by side, so you can run any mix of switches, receptacles, or combination devices in one opening. Box depth is 1.625 inches, which gives the interior wiring room a 4-gang device bank needs.
2) What conduit sizes can I bring into the RACO 953 steel box?
Half inch and 3/4 inch, in quantity. The 953 has sixteen concentric 1/2 and 3/4 inch knockouts, where one opening serves either trade size, plus six dedicated 1/2 inch and four dedicated 3/4 inch knockouts. That spread means you can feed and leave a 4-gang bank from several directions without hunting for a knockout in the right place.
3) Can I use the RACO 953 outdoors or in a wet location?
No. The 953 is a welded steel interior outlet box, not a weatherproof or gasketed enclosure. For an exposed exterior device, look at a die-cast aluminum weatherproof box such as the Mulberry Royal Mountie, or a Red-Dot conduit outlet box like the Thomas and Betts 2IH3-1 with threaded hubs.
4) Is the RACO 953 rated for a hazardous or classified area?
The RACO 953 is a UL Listed welded steel outlet box for commercial and industrial wiring, not a classified-location enclosure. For Class I or Class II areas, the Appleton GRJ Series and GRJS Series are explosionproof malleable iron conduit outlet boxes, and the Appleton GRT75 is a malleable iron round conduit outlet box in the same family of threaded conduit bodies. Those are conduit outlet boxes rather than 4-gang device boxes, so the device count and wiring space differ from the 953.
5) Is the RACO 953 UL Listed for commercial electrical work?
The 953 is UL Listed, which is what an inspector will look for on a steel device box in commercial or industrial work. That listing plus the welded steel body is why it gets specified on new construction and retrofit jobs where a plastic box will not pass.
6) Is a welded 4-gang steel box better than ganging separate boxes together?
A welded box like the RACO 953 comes as one piece, so there are no gangable sides to strip off and no seams to line up on the job. You set one box, and the four device positions are already square to each other. Ganging individual boxes gives you more freedom to build odd widths, but it adds assembly time and more joints. If the job calls for exactly four devices in a row, the welded 953 is the faster, more rigid answer.
7) What is the alternative to a steel 4-gang box for residential multi-gang work?
For houses and light residential, a nonmetallic multi-gang box like the Cantex EZ Series PVC residential outlet box is the usual pick, and it does not need bonding to the box itself. The RACO 953 goes the other way: welded steel, UL Listed, intended for commercial and industrial installs where metal raceway is being landed on the box through 1/2 and 3/4 inch knockouts.
8) I need a box for a range or dryer receptacle - will the RACO 953 work?
The RACO 953 is a 4-gang welded steel box sized for four standard devices side by side, such as ganged switches, receptacles, or combination devices. For a dedicated appliance outlet, the Pass & Seymour P242RRD is a thermoplastic range and dryer box built specifically for that application. The two are not interchangeable: one is a multi-device gang box, the other a single-purpose appliance box.
9) What is the difference between the RACO 953 and a conduit outlet box like the Red-Dot 2IH3-1?
The RACO 953 is a welded steel device box with a 1-5/8 in. depth and knockouts you punch for the conduit sizes you need - sixteen concentric 1/2 and 3/4 in., six dedicated 1/2 in., and four dedicated 3/4 in. The Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three fixed 1/2 in. threaded hubs, supplied in a pack of 100. The 953 gives four device positions and selectable knockout locations; the Red-Dot gives two device positions with preset threaded hub entries.
10) How do I order the RACO 953, and what part number do I give my supplier?
One configuration only. The manufacturer part number is 953, sold as a single model with no finish or size options to specify, so there is nothing to choose beyond quantity. Ask for RACO 953, the 4-gang welded steel outlet box at 1.625 inch depth.
