RACO RACO185 – Frequently Asked Questions

1) Will a RACO 185 box work with 1/2 in. EMT conduit runs?
Yes. The RACO 185 is built for conduit wiring systems and comes with fifteen 1/2 in. knockouts spread around the sides and back, so you can bring 1/2 in. EMT into the box from most directions without drilling. You still need the appropriate 1/2 in. connectors or couplings for the raceway type you're running, since those aren't part of the box.
2) Does the RACO 185 come with a mounting bracket or do I have to support it myself?
No bracket. The 185 ships as a bare 4 in. square box, so it has to be screwed directly to framing through the box's mounting holes or supported by the conduit system itself. If you want a box that nails to the face of a stud at a set depth, you need a bracketed version instead.
3) Do I need to order a cover separately for the RACO 185 square box?
Yes. The 185 is the box only. Any 4 in. square application needs a separate cover sized to the job, a flat blank cover for a junction box, or a raised device cover matched to your wall finish depth if you're mounting a switch or receptacle. Covers for 4 in. square boxes are a standard trade size, so they'll match the 185's footprint.
4) What does drawn steel mean on a RACO 185, and is it better than a welded box?
Drawn means the body is formed from a single piece of steel with no welded seams, so there are no joints to split if the box gets knocked around or pulled on during a conduit installation. Welded boxes are assembled from separate pieces and are typically how the deeper 4 in. square boxes are made. For a shallow 1-1/4 in. box like the 185, drawn construction is the stronger one-piece option.
5) Is the RACO 185 UL Listed for commercial and institutional work?
The 185 is UL Listed, which is what most commercial and institutional specs call for on a steel outlet or junction box in a conduit raceway. That makes it acceptable for code-compliant junction, outlet, and device wiring in commercial as well as residential construction.
6) Can I use the RACO 185 with NM (Romex) cable instead of conduit?
It's specified for conduit wiring systems, and the openings are plain 1/2 in. knockouts with no integral cable clamps. To run NM cable into it you'd have to add listed cable connectors at each knockout. If your job is all cable-fed, a box supplied with NM clamps is the cleaner choice.
7) What is the RACO part number for the 4 in. square drawn box with fifteen 1/2 in. knockouts?
RACO 185. That's the manufacturer part number for the 4 in. square drawn steel box, 1-1/4 in. deep, with fifteen 1/2 in. knockouts and no bracket.
8) I'm standardizing junction boxes across a building. Is the 185 a good box to spec in quantity?
For conduit-fed junction and outlet points where a shallow box will carry the conductor count, the 185 standardizes well: one UL Listed 4 in. square drawn box, 1-1/4 in. deep, with 1/2 in. knockouts on the sides and back so the same box covers entries from any direction. Where framing or fill forces a deeper enclosure, plan on a second, deeper 4 in. square box rather than trying to make the shallow one work everywhere.
