Pass & Seymour WPB23 – Frequently Asked Questions

1) Is the Pass & Seymour WPB23 weatherproof box rated for outdoor wet locations?
The WPB23 is UL Listed and CSA Listed for wet and/or damp locations, but only when it is installed with an appropriate cover. The box alone does not make the installation weatherproof; you need a matching single-gang weatherproof cover or a 4-screw mounting cover to close it out. It's suitable for both interior and exterior use.
2) Where are the conduit holes on the WPB23 1-gang box?
Three holes: one on each end and one in the back. That lets you feed conduit straight through end to end for a run, or come in from behind when you are surface mounting against a wall. Two closure plugs ship with the box so any hole you don't use gets sealed.
3) How much wiring volume does the WPB23 box give me for a GFCI receptacle?
Interior capacity is 18.5 cubic inches. That is the number you use for NEC box fill calculations, and you have to count the device, conductors, grounds and clamps against it. For a single GFCI plus a couple of 12 AWG circuit conductors and grounds it is generous; stuffing a feed-through plus a splice gets tight.
4) What covers fit the Pass & Seymour WPB23?
It takes standard 4-screw mounting covers and single-gang weatherproof covers. The cover is a separate purchase and it is what determines your location rating, so pick it for the device going in: a flip-lid or in-use (extra duty) cover for a receptacle, a lever or toggle cover for a switch, a blank cover for a junction point.
5) What weatherproof box should I use if the opening needs three devices instead of one?
The Pass & Seymour WPB23 is a 1-gang die-cast aluminum weatherproof box with 18.5 cubic inches of interior capacity, so it houses a single device. For a three-device exterior opening, the Mulberry 30601 is a 3-gang powdered die-cast aluminum weatherproof outlet box in the Royal Mountie series. Both are die-cast aluminum bodies intended for outdoor boxes; the difference is gang count, which also changes the cover you order, since the WPB23 takes standard 4-screw mounting covers and single-gang weatherproof covers.
6) Will a die-cast aluminum box like the WPB23 hold up on a coastal or corrosive exterior wall?
The body is heavy die-cast aluminum with a baked-on electrostatic polyester powder paint finish, gray, which is there for scratch and corrosion resistance in exterior exposure. Aluminum also avoids the rust-through you get at damaged paint on a steel box. For a parking structure, exterior lighting feed or an equipment yard it's the usual choice.
7) Do I need separate brackets to mount the WPB23, and how do I open the holes?
Mounting lugs come with every box, along with two closure plugs, so no separate bracket is needed for surface mounting. The hole openings are knockout studs: hit the one you want with a sharp hammer blow and it breaks out clean. Open only what you intend to use and plug the rest, since an open hole defeats the wet-location rating.
8) For a wet-location receptacle on a building exterior, which die-cast box carries the listings I need on the inspection?
The Pass & Seymour WPB23 is UL Listed and CSA Listed for wet and/or damp locations when installed with an appropriate cover, and its heavy die-cast aluminum body carries a baked-on electrostatic polyester powder paint finish for corrosion resistance. The comparable Mulberry 30601 is also a powdered die-cast aluminum weatherproof outlet box, but it is a 3-gang enclosure, so for a single exterior receptacle the WPB23 is the matching size.
9) How does the WPB23 weatherproof box come packaged for a multi-unit job?
Standard packaging is 12 each per carton, which works out well when you are doing a run of exterior receptacles across a property or roughing in multiple units. Each box in the carton includes its own closure plugs and mounting lugs.
10) Can the WPB23 be used indoors, or is it outdoor only?
Both. It's built for interior and exterior applications, so the same box works for a damp indoor spot like a mechanical room, car wash bay or walk-in cooler wall as it does on an exterior wall. Indoors you still pair it with an appropriate cover for the location rating you need.
