RACO 176 – Frequently Asked Questions

1) Will the RACO 176 octagon box work for a ceiling fan, or is it just a junction box?
The RACO 176 is a 4 inch drawn steel octagon box sold for outlet, junction, ceiling fixture and fan box applications in residential and light commercial wiring. Note that a fan still has to be supported per code by a listed fan-rated box or brace, and the 176's bracket is a wood stud bracket, not a joist fan brace. For a paddle fan, use it only where the fixture load is carried by framing, and confirm the fan's own support requirements.
2) Do I need separate cable connectors with the RACO 176 box?
No. The 176 has NMSC clamps built in, so nonmetallic sheathed cable (NM/Romex) lands and clamps right at the box without buying separate cable connectors. If you run EMT or armored cable instead, you'd need the appropriate fitting at one of the 1/2 in. knockouts, since the integral clamps are for NM cable.
3) Can I use the RACO 176 on metal studs?
Not as supplied. The 176 comes with a J-type bracket made for wood stud framing, which nails or screws to the face of a wood stud in new construction. For steel stud walls you want a box with a bracket intended for metal framing, or a bracketless box mounted with stud-specific clips.
4) How deep is the RACO 176 and how much wire volume does that give me?
It's a 2-1/8 in. deep 4 in. octagon box, which is the deepest standard drawn octagon depth and the one electricians reach for when a fixture, several cables, and wire nuts all have to live in the same box. If you're tight on joist or stud space, the shallower 1-1/2 in. octagon is the alternative, with correspondingly less fill capacity.
5) What is the difference between a drawn box and a welded box?
Drawn means the body is formed from one piece of steel rather than assembled and welded at the corners, so wall thickness stays consistent and there are no seams to open up. The RACO 176 is a drawn box. Welded construction is common on larger square boxes where a one-piece draw isn't practical; for a 4 in. octagon, drawn is the stronger, leak-free-corner option.
6) Is the RACO 176 octagon box UL Listed for inspection?
Yes, the 176 is UL Listed, which is what an inspector looks for on a metallic outlet box. It is a steel box, so it also serves as part of the equipment grounding path when bonded properly.
7) How many knockouts does the RACO 176 have, and what size?
Two 1/2 in. knockouts, which take standard 1/2 in. trade size conduit fittings or cable connectors. That's enough for a feed-through junction; if you need more entries than two, step up to a 4 in. square box with multiple knockout sizes.
8) What is the exact part number to order the RACO 4 in. drawn octagon box with NM clamps?
Order RACO 176. That single model number covers the 4 in. drawn steel octagon box at 2-1/8 in. deep with NMSC clamps and the wood stud bracket; there are no finish or size options to specify.
