TAYMAC SD350Z – Frequently Asked Questions

1) Will the TayMac SD350 weatherproof box accept 1/2 inch rigid conduit, and how many runs can I bring in?
The SD350 has three 1/2 in. threaded outlets, so you can land three separate 1/2 in. conduit runs on one box, or plug the ones you don't use. The threads take standard 1/2 in. threaded rigid or IMC conduit and fittings directly, no connectors needed.
2) Is the SD350 deep enough to fit a GFCI receptacle with the conductors folded behind it?
Depth is 2.715 in., which is the deep version of the TayMac 1-gang weatherproof box rather than the shallow one. That extra volume is why it is specified where a GFCI body, pigtails and a couple of splices all have to sit under a weatherproof cover. If you are wiring a plain switch with a single run in and out, a shallow box would do; for a GFCI or a device with multiple conduit entries, the deep box is the one to order.
3) Can the TayMac SD350 be used outdoors in a wet location?
Yes. The SD350 is a weatherproof box, UL Listed, and intended for exterior and wet-location work such as outdoor receptacles, switches and lighting connections. Wet-location rating depends on pairing it with a weatherproof cover assembly, which is ordered separately from the box.
4) What is the closest equivalent to the TayMac SD350 if I need a one-gang deep weatherproof box in gray?
The Pass & Seymour WPBD series is a weatherproof one-gang deep box supplied in gray, so it covers the same single-device deep-box role as the TayMac SD350. The SD350 itself is a 1-gang metallic weatherproof deep box with a 2.715 in. depth and three 1/2 in. threaded outlets, offered in White (SD350WH) and Bronze (SD350Z). Choose by the finish you need to match on the wall.
5) What is the three-gang option if the SD350 is too small for my outdoor panel of switches?
The Mulberry 30601 Royal Mountie is a 3-gang weatherproof outlet box in powdered die-cast aluminum, which suits a bank of three outdoor devices. The TayMac SD350 is a 1-gang metallic box with three 1/2 in. threaded conduit outlets - the three refers to conduit entries, not device positions, which is a common mix-up when sizing the opening.
6) Is the SD350 box metal or plastic?
Metallic construction. For a property manager or contractor comparing it to a PVC weatherproof box, the metal body is what you want where the box is exposed to sun, impact, or supports the weight of rigid conduit runs. It also means the box itself is part of the equipment grounding path when threaded metal conduit is landed in the hubs.
7) What colors does the TayMac SD350 deep box come in?
Two: white (SD350WH) and bronze (SD350Z). Bronze is the usual pick on brick, stone or dark trim; white matches painted siding and most standard weatherproof covers. Both are the same 1-gang deep box with three 1/2 in. threaded outlets, so choose on appearance only.
8) Does a cover come with the TayMac SD350 weatherproof box?
No cover is included. The SD350 is the box only, and it needs a 1-gang weatherproof cover or in-use cover to close out the installation. Order the cover, the device, and any closure plugs for unused 1/2 in. hubs along with it so the rough-in can be finished in one trip.
9) How does the construction of the TayMac SD350 compare with the aluminum weatherproof boxes?
The SD350 is built with metallic construction and is UL Listed for wet-location exterior use. Among the alternatives, the Pass & Seymour WPB two-gang box and the Mulberry 30601 Royal Mountie three-gang box are both die-cast aluminum, the Mulberry being powder coated. All three are weatherproof enclosures; the difference that usually decides it is gang count and the finish you need on the exterior wall.
