RACO RACO190 – Frequently Asked Questions

1) Will a standard 4 in. square cover or mud ring fit the RACO 190 box?
The RACO 190 is a 4 in. square box, which is the standard footprint for 4-square covers, device rings and mud rings. The box itself ships bare, so the cover or raised ring for your device has to be ordered separately along with any conduit connectors.
2) Can I use the RACO 190 with NM cable (Romex), or is it conduit only?
It is built for conduit wiring systems. The sixteen openings are 1/2 in. knockouts sized for 1/2 in. conduit connectors, and no cable clamps or bracket are included. If you are running NM cable you need a box with integral cable clamps instead.
3) How does the RACO 190 mount if it has no bracket?
It is a no-bracket box, so it mounts directly, screwed or bolted to the stud, strut, or surface through the box holes rather than hung from a nail-on or stud bracket. If you want a box positioned off a stud face to a set drywall depth, you want a bracketed version instead.
4) Is the RACO 190 a drawn box or a welded box, and does it matter?
Drawn. The 190 body is formed from a single piece of steel rather than welded from panels, so there are no seams at the corners. Inspectors and MRO buyers who want a one-piece steel enclosure for conduit work get that here.
5) Does the RACO 190 need a separate grounding screw or pigtail?
No separate grounding screw is needed for the box itself. The 190 has an integrated raised ground, so the equipment grounding conductor lands directly on the box without drilling or tapping.
6) Is the RACO 190 box UL Listed for commercial work?
Yes, the 190 is UL Listed, which is what most commercial and institutional specs call for on a steel outlet or junction box.
