Pass & Seymour S120JFAN – Frequently Asked Questions

1) Is the Pass & Seymour S120JFAN rated to hang a ceiling fan, or is it only for light fixtures?
The S120JFAN is UL Listed for both ceiling fan and fixture support. The support comes from an angled metal mounting bracket that fastens to the building structure rather than to the drywall, which is what lets it carry a fan instead of just a light. If you only need a lighting outlet, a standard non-fan-rated round box will do, but fan duty requires a fan-rated box like this one.
2) Will a ceiling fan with a 3-1/2 inch mounting strap bolt to the S120JFAN box?
Yes. The S120JFAN 4-inch round ceiling box accepts fans or fixtures using either a 2.75-inch or a 3.5-inch mounting strap, which covers the two spacings almost every residential and commercial fan canopy ships with. Bring the strap that came with the fan; you do not need an adapter for either pattern.
3) Can the S120JFAN be installed in an existing ceiling, or is it new-construction only?
This is a bracket-mounted new-work box. The metal bracket fastens directly to building structure, so you need access to a joist, which in a finished ceiling means opening the drywall at the location. Its 4-inch round profile drops into standard round ceiling openings, so a retrofit is straightforward once you have the structure exposed. If you cannot open the ceiling, look for an old-work fan brace box that expands between joists through the existing hole instead.
4) Is the Pass & Seymour S120JFAN box metal or plastic, and does it need to be bonded?
The body is black Noryl thermoplastic, so it is non-conductive and there is nothing on the box itself to bond. Only the mounting bracket is metal. Equipment grounds still get joined inside the box and carried to the fan or fixture as usual; a nonmetallic box just means the enclosure is not part of the ground path the way a steel box would be.
5) How do I get the ceiling box flush with the drywall when I set it?
The S120JFAN has a built-in depth-mounting gauge, an alignment guide molded into the box that sets it at the right depth relative to the finished ceiling surface. Set the gauge for your ceiling material thickness before you drive the bracket, and the fan canopy sits tight against the finish with no shimming afterward.
6) Do I need separate cable clamps or connectors for the S120JFAN ceiling box?
No extra clamps. The Auto Clamp system is molded into the box, so NM cable is secured as it enters without adding connectors or hardware. What you do supply is the fan or fixture mounting strap and screws, which come with the fan, plus your wire connectors.
7) If I'm standardizing ceiling boxes across a building, is one fan-rated box fine everywhere, including at plain light fixtures?
Yes, and it is a common way to spec a portfolio. Because the S120JFAN is UL Listed for both fan and fixture duty, one box covers both conditions, so a unit that later gets a ceiling fan added does not need the ceiling opened again. All units are the same black 4-inch round thermoplastic box under part number S120JFAN, so there is a single item to stock.
8) Can I spec the S120JFAN on a commercial job, or is it a residential box?
It is used in both. Pass & Seymour lists it for residential fan installs and for commercial fixture mounting, including multi-unit residential, office, retail and light industrial work. It is UL Listed and RoHS compliant, and it is made in the United States, which matters on jobs carrying domestic-sourcing language.
