Pass & Seymour WPBP50-CC – Frequently Asked Questions

1) What does the Pass & Seymour WPBP closure plug actually do, and where does it go?
It is a threaded plug that screws into an unused threaded opening on a weatherproof electrical box or cover, sealing it against moisture and debris. Use it when a box has more hubs or threaded ports than you are running conduit into, so the enclosure stays weathertight on outdoor and wet-location work.
2) What trade sizes does the WPBP closure plug come in, and how do I pick the right one?
Two sizes: 1/2-in (WPBP50-CC) and 3/4-in (WPBP75-CC). Match the plug to the trade size of the threaded hub you are sealing, not to the conduit you are running elsewhere on the box. A 1/2-in plug will not thread into a 3/4-in hub, so count your open hubs by size before ordering.
3) Can I use a WPBP closure plug to seal a punched knockout instead of a threaded hub?
It is a threaded plug, so it needs threads to bite into. A plain punched knockout in a sheet metal box has no thread, and for that you want a knockout seal or closure plug made for unthreaded openings. Use the WPBP where the box or cover has a machined threaded port in 1/2-in or 3/4-in trade size.
4) Is the WPBP plug listed for use in wet locations?
The WPBP closure plug is cULus Listed and built for weatherproof enclosures in outdoor and wet-location service. That listing covers both the 1/2-in and 3/4-in versions, which share the same construction.
5) What are the exact part numbers for the Pass & Seymour WPBP closure plugs?
WPBP50-CC is the 1/2-in plug and WPBP75-CC is the 3/4-in. Both are gray and part of the WPBP series. Country of origin is India.
6) Do I need any tools to install a WPBP closure plug?
No special tools. It threads straight into the opening, so it goes in by hand or with a standard wrench depending on how tight you want it seated. That makes it practical for retrofit work where the box is already mounted and wired.
7) Will the gray WPBP plug match my existing weatherproof covers?
The plug is gray, which is the standard color for Pass & Seymour weatherproof device boxes and covers, so it blends with gray enclosures already on the building. If your boxes are bronze or white, expect a visible color difference.
8) How many WPBP closure plugs come in a pack?
They ship 12 each per pack. For property managers or MRO buyers stocking a truck or a shop, one pack of each trade size covers most weatherproof box work since the 1/2-in and 3/4-in hubs are the two you encounter.
