Bell 5363-0 – Frequently Asked Questions
1) Will the Bell 5363-0 fit a square or rectangular weatherproof box?
No. The 5363-0 is a round configuration and is meant to extend round weatherproof boxes. If the existing enclosure on the wall is a square or rectangular weatherproof box, this adapter won't line up with the mounting pattern, and you need an extension body matched to that box shape instead.
2) What size conduit does the Bell 5363-0 accept?
All four outlets on the 5363-0 are 1/2 inch threaded hubs, so they take 1/2 inch threaded conduit fittings, close nipples, or weatherproof accessories with 1/2 inch male thread. Unused outlets have to be closed off with plugs to keep the enclosure weathertight.
3) Is the Bell 5363-0 extension adapter UL Listed for outdoor wet-location work?
The 5363-0 is both UL Listed and CSA Certified, which is what an inspector or a facility spec generally wants to see on exposed weatherproof wiring. It is built for weatherproof outdoor electrical installations and conduit connections in wet locations, and the CSA certification covers Canadian jobs as well.
4) Is this extension adapter metal or plastic, and will it corrode outdoors?
Aluminum, metallic construction, not PVC. Aluminum holds up to outdoor exposure and gives you mechanical strength on a box that may be carrying conduit runs. Because it is metallic, the extension is part of the equipment grounding path once installed, which is a point in its favour where a metallic raceway system is already in place.
5) How much does the Bell 5363-0 stick out from the wall?
Depth is 1.625 inches, so the extension adds a little over an inch and a half to whatever the existing box and cover already project. That keeps the assembly reasonably low profile on a walkway, a railing, or a tight soffit, but budget for the added stack-up before you order a device cover to go over it.
6) What is the exact part number to order for the Bell round weatherproof extension adapter with four 1/2 inch hubs?
Order Bell 5363-0. That MPN is the round aluminum extension adapter in gray with four 1/2 inch threaded outlets. There is one configuration, so no finish, hub-size, or depth suffix has to be specified.
7) Do I get a cover, plugs, or a gasket with the Bell 5363-0?
The 5363-0 is the extension body itself. Plan on ordering the weatherproof cover or device plate for the front, threaded closure plugs for any of the four outlets you don't use, and any gasket or sealant your installation calls for, so the assembly stays weathertight.
8) Will the gray finish on the 5363-0 match the other weatherproof boxes and covers on the building?
It's finished gray, the standard color for weatherproof boxes and covers, so it blends with existing gray enclosures on a building exterior. For a property manager standardizing exterior fittings across multiple units, gray is the safe match; it will not match a bronze or white weatherproof cover line.
