TAYMAC SB350S – Frequently Asked Questions
1) How many conduit openings does the TAYMAC SB350S weatherproof box have, and what size are they?
The SB350S has three threaded outlets, each 1/2 inch, so you can bring conduit in and out of the same single-gang box and still have a spare opening for a run to the next device. The threads take standard 1/2 inch trade size rigid or IMC conduit and fittings.
2) Is the TAYMAC SB350S box deep enough for a GFCI receptacle and conduit wiring?
Box depth is 2.09 inches, which is the usual single-gang weatherproof depth for a device plus a couple of conduit connections. If you are stuffing a GFCI with several #12 conductors and multiple conduit runs, check your box fill; a deep one-gang like the Pass & Seymour WPBD Series gives you more room.
3) Can the TAYMAC SB350S be used outdoors in a wet location?
Yes. The SB350S is a UL Listed weatherproof wall box intended for outdoor and wet-location conduit work. The enclosure itself is only half the job, though: weatherproofing depends on a proper cover or in-use cover and sealed threaded conduit entries at every opening you use. Plug any unused 1/2 inch outlet with a threaded close-up plug.
4) I need to mount two devices outdoors - what should I use instead of the TAYMAC SB350S?
The SB350S is a one-gang box, so it will only take a single device. For a two-device exterior opening, step up to the Pass & Seymour WPB Series weatherproof two-gang box in die-cast aluminum. It keeps the same surface-mount weatherproof approach but gives you the second gang, so you are not ganging two single boxes to feed a duplex-plus-switch arrangement.
5) Is the TAYMAC SB350S metal or PVC?
Metal, metallic construction, finished gray. That matters two ways: it needs to be bonded as part of your equipment grounding path, and it mates with metal conduit systems rather than nonmetallic. For an all-plastic run you would want a nonmetallic box instead.
6) Does the TAYMAC SB350S mount flush in a wall or on the surface?
Surface mount. It is a wall box for surface installation on an exterior wall or structure, with conduit entering through the threaded outlets. It is not a flush, in-wall box, so it does not replace a cut-in old work box.
7) Does the TAYMAC SB350S come with a cover?
The SB350S is the box only. You order the cover separately and the choice drives your compliance: a flip-lid cover for a location where nothing stays plugged in, or an in-use (extra duty) weatherproof cover where a cord remains connected outdoors. Match the cover to the device you are installing, GFCI duplex versus toggle switch.
8) What is the three-gang equivalent for a weatherproof outlet box like the TAYMAC SB350S?
For a three-device exterior location, the Mulberry 30601 Royal Mountie is a powdered die-cast aluminum three-gang weatherproof outlet box. The SB350S covers single-device installations with its one-gang metallic body, so on a bank of three devices the Mulberry three-gang is the direct answer rather than a multiple-box run.
9) If I need more wiring room than the TAYMAC SB350S gives me in one gang, what are my options?
The SB350S runs 2.09 in. deep in a one-gang footprint. When you need additional volume without adding a gang, the Pass & Seymour WPBD Series is a one-gang deep box in gray and is the logical move for crowded conductor counts or a bulky device yoke. Both are gray, so a mixed exterior wall still reads consistently.
10) Will the gray TAYMAC SB350S match the other weatherproof boxes on my building?
It is finished gray over metal, the standard color for weatherproof electrical enclosures, so it lines up visually with most existing exterior boxes and covers. The Pass & Seymour WPBD deep one-gang box is also gray if you are mixing depths across a property and want them to look alike.
11) What is the TAYMAC part number and UPC for the single-gang three-hole weatherproof box?
TAYMAC model SB350S, UPC 092326110839. One configuration only: one-gang, three 1/2 inch threaded outlets, gray metallic.
