Pass & Seymour 3723-FS – Frequently Asked Questions

1) Will the Pass & Seymour 3723-FS weatherproof cover fit a single gang decorator or GFCI receptacle?
Yes. The 3723-FS is a single gang cover sized for decorator-style openings, so it suits decorator switches, GFCI receptacles, and power outlets with that rectangular device opening. It mounts vertically with 4 screws. It will not work over a standard duplex (two round holes) configuration, since the opening is cut for decorator devices.
2) Does the 3723-FS self-closing cover meet code for an outdoor receptacle that is not in use?
It is built to the 2005 NEC Section 406.8(A) and 406.8(B)(2) requirements for weatherproof device covers, which is the while-not-in-use category for wet and damp location devices. The lid closes on its own so the opening is protected once a plug is pulled. Note that a self-closing cover of this style protects the device when nothing is plugged in; an extra-duty in-use (bubble) cover is what you want where a cord stays connected in a wet location.
3) Can an NSi CL Series clear acrylic cover be used in place of the Pass & Seymour 3723-FS weatherproof cover?
No, they protect different things. The Pass & Seymour 3723-FS is a single gang weatherproof device cover in gray thermoplastic that mounts over a decorator switch, receptacle, GFCI, or power outlet opening with four vertical screws and self-closes to shield the device from rain and debris, and it carries CSA, UL, and cULus listings. The NSi CL Series cover is a clear acrylic cover for a power distribution block, which guards energized block terminals inside an enclosure or panel rather than a wiring device in a single gang box. Neither one substitutes for the other on the opening the other is made for.
4) Is this Pass & Seymour weatherproof cover UL listed for a commercial inspection?
The cover carries cULus Listing and is also CSA and UL Listed, so it satisfies both US and Canadian listing requirements on commercial, industrial, and residential work.
5) Can the 3723-FS cover be locked shut on a jobsite or a tenant exterior wall?
Yes, the lid is padlockable. That lets a property manager or contractor lock out an exterior receptacle or switch so the public cannot use it, which is common on multi-family exteriors and construction sites.
6) Does the gray 3723-FS cover need to be mounted vertically?
It is a vertical-mount cover, so the device box should be oriented vertically for the self-closing lid to drop shut under its own weight. On a horizontally oriented box you need a horizontal-mount version of the cover instead.
7) What is the 3723-FS cover made of, and will it hold up outdoors?
Thermoplastic is the base material, reinforced, with a clear polycarbonate lid over it. The clear lid lets you see the device and any GFCI indicator without opening the cover, and the finish is matte gray.
8) How is the Pass & Seymour 3723-FS cover packaged for a bulk order?
It ships 50 each per pack, which fits standardizing a building or a multi-unit exterior rather than a single replacement. The part is made in Mexico.
