Pass & Seymour WPB23-BR – Frequently Asked Questions

1) Is the Pass & Seymour WPB weatherproof box rated for wet locations on its own, or do I need a cover?
The WPB die-cast aluminum box is UL Listed and CSA Listed for wet and/or damp locations only when paired with an appropriate cover. The box by itself is not a sealed assembly, so a single-gang weatherproof cover (or a standard 4-screw mounting cover for dry interior use) has to be ordered with it to get the wet-location rating.
2) What size conduit does the WPB weatherproof box take, and where are the openings?
Three 3/4 inch hub openings: one in each end and one in the back. That gives you a straight through-run with either end, or a back feed where conduit comes out of the wall. Two closure plugs come with the box so any opening you do not use gets sealed.
3) I need a weatherproof box for three devices instead of one - what should I use instead of the Pass & Seymour WPB?
The Pass & Seymour WPB is a single-gang die-cast aluminum weatherproof box, so it holds one device only. For a three-device opening, the Mulberry 30601 Royal Mountie is a 3-gang weatherproof outlet box, also powder-coated die-cast aluminum. Both share the same basic construction approach; the difference is gang count, so confirm the device plate and cover you are using matches the gang count before ordering.
4) Will an 18.5 cubic inch weatherproof box hold a GFCI receptacle and pigtails?
18.5 cubic inches is the internal volume of the WPB single-gang box, which is generous for a single-gang enclosure and leaves room for a deeper device body plus the conductors and connectors behind it. Capacity is the same 18.5 cu. in. in all three colors.
5) What colors does the Pass & Seymour WPB box come in and what are the part numbers?
Three finishes, all die-cast aluminum with baked-on electrostatic polyester powder paint: Bronze (WPB23-BR), White (WPB23-W), and Gray (WPB33). Construction and the 18.5 cu. in. volume are identical across the three, so pick by what matches the siding, trim, or the devices already on the building.
6) Does the WPB box come with mounting hardware or do I have to buy it separately?
Mounting lugs and two closure plugs are furnished with the box. You supply the fasteners suited to the surface you are anchoring to, plus the cover and gasket.
7) Is the Mulberry Royal Mountie 30601 a direct replacement for a Pass & Seymour WPB box?
No. The Mulberry 30601 belongs to the Royal Mountie series and is a 3-gang weatherproof outlet box, while the Pass & Seymour WPB is a single-gang box with 18.5 cu. in. capacity and 3-hole 3/4 inch conduit openings (one each end, one in back). Swapping one for the other changes the number of devices the opening supports and the cover footprint, so it is not a one-for-one substitution on an existing single-gang mount.
8) For an exterior wall where I only need one receptacle, which box fits better - the WPB or a 3-gang aluminum box?
For a single receptacle, the Pass & Seymour WPB is the matching size: single-gang, 18.5 cu. in., UL Listed and CSA Listed for wet and damp locations with an appropriate cover, and it accepts standard 4-screw mounting covers and single-gang weatherproof covers. The Mulberry 30601 Royal Mountie is a 3-gang box, which would leave two unused device positions and require a 3-gang weatherproof cover.
9) Is a die-cast aluminum weatherproof box better than PVC for a coastal or corrosive exterior?
The WPB body is heavy die-cast aluminum with a baked-on electrostatic polyester powder paint finish, which is what gives it scratch and corrosion resistance outdoors while staying rigid enough to carry conduit runs. Aluminum is the normal choice where the box is threaded to rigid or IMC conduit; nonmetallic boxes are used where the raceway is PVC and no bonding path through the box is wanted.
10) How do you open the knockouts on the Pass & Seymour WPB box without cracking the casting?
The knockout studs are designed to come out with a single sharp hammer blow, which leaves a clean hole. One firm hit, not repeated taps, and the hub threads stay intact.
11) Can the WPB weatherproof box be used indoors as a surface-mount box?
Yes. It is built for both interior and exterior wiring, and indoors it accepts standard 4-screw mounting covers, so it works as a surface-mounted single-gang box on block, concrete, or exposed conduit in a shop or garage.
12) Do both the Pass & Seymour WPB and the Mulberry 30601 use the same kind of corrosion-resistant finish?
Both are powder-coated die-cast aluminum enclosures. The Pass & Seymour WPB uses a baked-on electrostatic polyester powder paint over a heavy die-cast aluminum body and is offered in Bronze, Gray, and White; the Mulberry 30601 Royal Mountie is a powdered die cast aluminum box. If finish color needs to match surrounding trim or siding across an exterior run, the WPB gives you the three color choices.
13) How is the Pass & Seymour WPB box packaged for a job order?
It ships 12 each per pack, which suits standardizing one finish across a run of exterior openings on a multi-family or commercial job. Country of origin is India.
