TAYMAC SB375S – Frequently Asked Questions

1) Can I use a weatherproof cast box like the TAYMAC SB375S outdoors in a wet location?
That's what it's built for. The SB375S is a cast metal weatherproof box with threaded hubs, intended for exterior and wet or damp location wiring on conduit systems, and it is UL Listed. The threaded hubs are what make the connection weathertight, so pair it with a gasketed weatherproof cover rated for your device and for in-use or not-in-use conditions as your installation requires.
2) Does the SB375S come with a cover, or do I have to order one separately?
The SB375S is the box only, a 1-gang weatherproof wall box with three threaded 3/4 in. hubs. You order the cover separately and match it to the device: a flip-lid receptacle cover, a weatherproof switch cover, or an in-use (while-in-use) cover if a cord stays plugged in. Closure plugs are also needed for any of the three hubs you don't use.
3) I need to mount two devices outdoors instead of one. What should I use?
Step up to the Pass & Seymour WPB Series weatherproof two-gang box in die-cast aluminum. The TAYMAC SB375S is a one-gang box, so it will only accept a single-gang device such as one switch or one receptacle. For a two-device outdoor opening, the WPB two-gang box is the correct size; for three devices, the Mulberry 30601 Royal Mountie is a three-gang weatherproof box in powdered die cast aluminum.
4) What is a one-gang weatherproof box alternative to the TAYMAC SB375S?
The Pass & Seymour WPBD Series weatherproof one-gang deep box is the closest single-gang peer. Like the TAYMAC SB375S, it is a one-gang weatherproof box in a gray finish. The SB375S is cast metal with three 3/4 in. threaded outlets and a 2.09 in. depth, while the WPBD is a deep-body box in the WPBD series. Both cover the same single-device outdoor opening, so the decision usually comes down to the interior wiring volume you need behind the device.
5) Is the TAYMAC SB375S aluminum or steel, and will it corrode outside?
The body is cast metal with metallic construction and a gray finish. Peer weatherproof boxes we carry are specifically die-cast aluminum, such as the Pass and Seymour WPB-232 and the powdered die cast aluminum Mulberry 30601 Royal Mountie. For coastal or chemically aggressive exposure, confirm the material suits the environment and bond the box properly, since a metal enclosure on conduit is part of the equipment grounding path.
6) What do I do with the extra hubs on a three-hub weatherproof box if I only run one conduit?
Plug them. With three 3/4 in. threaded outlets you can feed through, branch off, or bring in from the back or either side, but every unused hub has to be sealed with a 3/4 in. threaded closure plug to keep the box weathertight and code compliant.
7) Can I use a threaded-hub cast box like this with NM cable or PVC conduit?
The SB375S hubs are threaded for 3/4 in. conduit, so it's intended for a rigid or IMC raceway system rather than cable. PVC can be adapted with a male terminal adapter threaded into the hub. Romex is not a wet-location wiring method and has no fitting path into a threaded weatherproof hub, so this is not the box for a cable job.
8) Is the Mulberry 30601 Royal Mountie a substitute for the TAYMAC SB375S?
No. The Mulberry 30601 is a three-gang weatherproof outlet box, while the TAYMAC SB375S is a one-gang box sized for a single wiring device. They are both cast-aluminum-family weatherproof boxes for exterior use, but the gang count differs, so the 30601 will not drop into a single-gang opening or accept a single-gang cover.
9) What is the MPN for the TAYMAC gray 1-gang weatherproof cast box?
TAYMAC SB375S. It's the manufacturer part number and the model designation for the 1-gang, three-hub, gray cast metal weatherproof box.
