RACO 232MS – Frequently Asked Questions

1) Will the RACO 232MS mount to metal studs, or is it only for wood framing?
Both. The 232MS comes with an M bracket rated for metal or wood studs, so the same box covers steel stud commercial partitions and wood stud residential framing without changing part numbers.
2) How deep is the RACO 232MS 4 inch square box, and will it give me room for a device plus pigtails?
It's a 4 in. square box with a 2-1/8 in. (2.125 in.) deep body, which is the deeper of the two common 4-square depths and leaves working room for a device and conductors rather than forcing a splice-only install.
3) What conduit sizes will the knockouts on the RACO 232MS take?
The box has 1/2 in. knockouts plus 1/2 - 3/4 in. combination (TKO) knockouts, so you can land 1/2 in. connectors straight away or pop the outer ring for 3/4 in. without a step bit or a reducing washer.
4) Does the RACO 232MS come with a ground already in it?
Yes. The 232MS ships with a raised ground and an 8 in. #12 copper pigtail already attached, so the equipment ground is ready to splice when you rough in. No separate ground clip or screw to add.
5) Welded or drawn 4 square box, which should I spec?
The 232MS is a welded box. Welded construction is the stronger of the two for 4 in. square bodies, which is why it's the usual pick for commercial rough-in and anywhere the box takes abuse during framing. Drawn boxes are the lighter-duty alternative.
6) Is the RACO 232MS rated for 600 volt commercial branch circuits?
Yes, the 232MS carries a 600V rating and is UL Listed, which covers standard 120/208 and 277/480 branch circuit work in commercial and industrial buildings as well as residential wiring.
7) I need a box with threaded 3/4 in. hubs instead of knockouts - what should I order instead of the 232MS?
The RACO 232MS ships with 1/2 in. and 1/2 - 3/4 in. combination (TKO) knockouts, which are punched openings rather than threaded hubs. For an assembly that arrives with hubs already in place, the Thomas & Betts Red-Dot 2IH3-2 is a 2-gang RT box with three 3/4 in. hubs, sold in packs of 100. Choose by how the raceway terminates: hubs land conduit directly, knockouts take a connector sized to the opening you punch.
8) Which of the two is a UL Listed welded-body box for a 600V branch circuit?
The RACO 232MS is the welded-construction 4 in. square box here, UL Listed and rated 600V, with a raised ground and an 8 in. #12 copper pigtail included for equipment grounding. The Red-Dot 2IH3-2 from Thomas & Betts is identified as a 2-gang RT box with three 3/4 in. hubs. If your specification calls out a welded 4 in. square body on a stud bracket with the ground pigtail already fitted, the 232MS is the part that matches that description.
9) Can I standardize on the 232MS across a whole building's outlet and junction boxes?
That's what it's built for. One part number covers metal and wood stud framing via the M bracket, handles 1/2 in. or 3/4 in. raceway through the combination knockouts, and arrives pre-grounded with the copper pigtail. For a property or facilities crew that means one box on the truck instead of three, with the cover or ring chosen per opening.
