Pass & Seymour S120RGAC – Frequently Asked Questions

1) Can I hang a ceiling fan from the Pass & Seymour S120RGAC round box?
Yes. The S120RGAC 4-inch round ceiling box is UL Listed for fan and fixture support, so it can carry a ceiling fan as well as a lighting fixture. That listing is what separates it from a plain lighting-only box, and it is the reason it gets specified on fan rough-ins in houses, apartments, and commercial spaces.
2) Is the S120RGAC ceiling box metal or plastic, and does it need to be grounded like a metal box?
It's molded thermoplastic, not metal. Pass & Seymour builds the S120RGAC from impact-resistant Noryl, which is fully non-conductive, so the box body itself is not part of the grounding path the way a steel box is. Ground conductors still land on the fixture and any device per code, but there is no box-bonding screw requirement created by the enclosure material.
3) Do I need cable clamps or connectors for this Pass & Seymour round ceiling box?
No separate clamps needed. The S120RGAC has auto-clamp cable management molded into the box, so the cable is held without adding hardware or tools at rough-in. That is one less item on the material list for a fixture or fan drop.
4) How do I set the box flush with the finished ceiling?
The S120RGAC has a depth-mounting gauge built into the box. You set the box against the framing using that gauge so the front edge lands correctly relative to the finished ceiling surface, instead of eyeballing drywall thickness and shimming later at trim-out.
5) Will a standard 4-inch round fixture canopy or fan bracket line up with this box?
The S120RGAC is a 4-inch round ceiling box, which is the common size fixture canopies and fan mounting brackets are made to cover and screw into. Standard sizing is what makes it usable across residential and commercial fixture and fan work without hunting for an odd trim.
6) Is this ceiling box only for houses, or can I use it on commercial and multifamily jobs?
Both. Pass & Seymour lists the S120RGAC for residential, multi-unit residential, and commercial electrical installations, including commercial lighting, office buildings, and apartment work, on new construction and renovation alike. Property managers standardizing fixture boxes across a portfolio can use one part number for all of it.
7) Where is the Pass & Seymour S120RGAC made? I have a domestic-content requirement on this job.
Country of origin on the S120RGAC round ceiling box is the United States. That matters on government, institutional, and publicly funded work where domestic sourcing gets documented in the submittal.
8) What color is the S120RGAC box and does it matter once it is installed?
Black. On the S120RGAC the black is just the Noryl thermoplastic itself, not a coating, and the box sits behind the fixture canopy once trimmed out, so it reads clean if any edge is visible. The color has no bearing on fit.
