Pass & Seymour S1-18-R – Frequently Asked Questions

1) Is the Pass & Seymour S118R box metal or plastic?
The S118R is a molded thermoplastic device box, not steel. That matters on two fronts: there is no metal box to bond, so your equipment grounding path has to be carried by the wiring method itself, and the nonmetallic body won't rust in damp locations the way a steel box can. Color is grey.
2) Is the Pass & Seymour S118R UL Listed and acceptable for a commercial job spec?
The S118R is UL Listed and RoHS compliant, and it's made in the United States, which covers the domestic-preference language that shows up on a lot of institutional and government specs.
3) What is the Quick/Click feature on the Pass & Seymour S118R switch box?
It is a device mounting feature that lets a switch or receptacle seat and secure quickly without fighting the screw holes. The mounting points also won't strip when over-torqued, which is the usual failure on a plastic box when someone runs a screw gun down hard on a device.
4) Can the S118R be used for both a light switch and a receptacle?
Yes. It's a single-device switch and outlet box, so it takes a standard yoke-mounted device, switch or receptacle, with the same mounting provisions either way.
5) What is the correct part number to order the Pass & Seymour grey thermoplastic switch box?
Order it as Pass & Seymour S118R; the manufacturer part number reads S1-18-R. Only the one model is offered, so there is no finish or size option to specify.
6) Is the S118R meant for new construction or for remodel work?
Both are listed applications: new construction rough-in wiring as well as remodel and retrofit electrical work, for residential and commercial switch and receptacle installs.
