Pass & Seymour WPBP75 – Frequently Asked Questions

1) What size knockouts do the Pass & Seymour WPBP box plugs fit?
The WPBP Series closure plugs come in two trade sizes, 3/4 inch (WPBP75) and 1 inch (WPBP100), sized for standard weatherproof box openings. Match the plug to the knockout you are closing off, not to the conduit you removed. If you have a mix of both on a building, both sizes are part of the same family so you can standardize on one line.
2) Is the Pass & Seymour WPBP plug UL and CSA listed for inspection?
Both. The WPBP Series weatherproof box plug is UL Listed and CSA Listed, which covers jobs on either side of the border and gives an inspector a listed closure on the unused opening.
3) Can I use an aluminum box plug outdoors in a wet location?
Aluminum is what the WPBP plug is made from, and it is intended for outdoor and wet-location weatherproof box work as well as indoor installs. The aluminum body resists corrosion, which is the reason to pick it over a plain steel closure for exterior enclosures.
4) How many box plugs come in a pack of the WPBP Series?
They ship 100 each per package. That is bulk contractor packaging, so it suits a service truck or an MRO crib stocking both 3/4 inch and 1 inch closures rather than a one-off repair.
5) What is a weatherproof box plug actually for, and do I need one if the knockout is unused?
A closure plug seals an unused opening in a weatherproof electrical box so moisture, dust, and debris stay out of the wiring compartment. An open knockout defeats the enclosure's weather rating, so yes, any opening you are not using should be plugged. The WPBP Series is made for exactly that on commercial, industrial, and residential weatherproof assemblies.
6) Do I need any special tools to install a WPBP closure plug?
No special tooling. The WPBP plug threads into a compatible weatherproof box opening and seals it, with no additional parts needed to finish the closure.
