TAYMAC RB550S – Frequently Asked Questions

1) Is the TayMac RB550S weatherproof box rated for outdoor wet-location use?
The RB550S is built as a weatherproof outlet box for exterior, exposed, and outdoor electrical work, including wet-location wiring. The body is die-cast metal with a powder-coated exterior finish for added protection against moisture and weather exposure. Note that a weatherproof box needs a matching weatherproof cover or in-use cover to actually close out the opening, ordered separately.
2) How much wiring room does the RB550S outlet box give me?
Interior volume is 16 cubic inches on the 4-inch box footprint, which is the usable space for splices, a receptacle or switch, and device mounting hardware. Use that figure when you run your box fill calculation for the number and size of conductors entering the box.
3) How many gangs is the TayMac RB550S, and what if I need two or three devices?
The RB550S is a single-device 4-inch weatherproof outlet box, so it takes one receptacle or switch. For multi-device exterior work, the Pass & Seymour WPB Series weatherproof box is a two-gang die-cast aluminum box, and the Mulberry 30601 Royal Mountie is a powdered die-cast aluminum three-gang weatherproof box.
4) What is a two-gang alternative to the TayMac RB550S weatherproof outlet box?
The RB550S is a single 4-inch die-cast metal weatherproof box with a 16 cubic inch interior, so it suits one device. For a two-device opening, the Pass & Seymour WPB series weatherproof two-gang box is also die-cast aluminum and carries two gangs in one enclosure, which avoids ganging two single boxes on an exterior wall.
5) The RB550S is not deep enough for my splices - is there a deeper single-gang weatherproof box?
The RB550S provides 16 cubic inches of interior volume in a 4-inch die-cast metal body. If the device and conductors need more room behind them, the Pass & Seymour WPBD series is a one-gang deep weatherproof box in gray, built in the deep configuration for the same single-device footprint.
6) Is the RB550S deep enough for a GFCI receptacle with pigtails?
You get 16 cubic inches to work with, which is enough for a device plus splices on a straightforward exterior run. If you are stuffing a GFCI with pigtails plus multiple cable entries and want more room, Pass & Seymour's WPBD Series is a one-gang deep weatherproof box in gray and a better choice for crowded box fill.
7) What part number do I order for the TayMac weatherproof box, and can I standardize on it across a property?
Order it as RB550S, the manufacturer part number. It is a single-model item, so every unit is the same 4-inch, 16 cubic inch weatherproof box with the same powder-coated die-cast body, which makes it straightforward to standardize exterior receptacle locations across a building or portfolio.
8) Can the RB550S be surface mounted to an exterior wall or column?
Yes. The compact 4-inch profile is intended for surface mounting to exterior walls, columns, or other structures where an outdoor receptacle or switch is needed, on new construction or retrofit exterior wiring.
9) Is the Pass & Seymour WPBD a direct swap for the TayMac RB550S?
They are not identical. Both are single-gang weatherproof boxes for exterior use, but the RB550S is die-cast metal with a powder-coated finish rated at 16 cubic inches, while the WPBD is the deep version of the Pass & Seymour one-gang weatherproof box in gray. If an existing cover and mounting pattern were set up for the RB550S, confirm the cover and conduit entries line up before swapping in the deeper body.
10) How do the Mulberry Royal Mountie and TayMac RB550S compare on construction?
Both are die-cast aluminum-family weatherproof outlet boxes with an applied powder finish for exterior service. The difference is capacity and layout: the RB550S is a single 4-inch box with 16 cubic inches of interior volume, while the Mulberry 30601 Royal Mountie is a three-gang body. Choose by how many devices the exterior location has to carry.
11) Die-cast metal versus aluminum weatherproof boxes, which should I use outdoors?
The RB550S uses a die-cast metal body with a powder-coated finish, which is what gives it impact resistance plus a coated surface against moisture. The comparable Pass & Seymour WPB and Mulberry Royal Mountie boxes are die-cast aluminum. Practical difference on the job is gang count and depth rather than weather performance, so pick on device count and wiring room.
