RACO 570RAC – Frequently Asked Questions
1) Can RACO 570RAC switch boxes be ganged together for a two or three gang device assembly?
Yes. The 570RAC has removable gangable sides, so you can join boxes side by side for multi-device assemblies. Each box is a 3 in. x 2 in. single-gang body, 2-3/4 in. deep, so a two-gang assembly is two boxes joined rather than one wider shell. If you would rather start from a factory 2-gang body, the Allied Moulded 2302-NKV is a 2-gang box, though it is fiberglass reinforced rather than steel and is not gangable in the same way.
2) Will the RACO 570RAC accept MC cable without separate connectors?
It will. The box has integrated clamps for Armored Cable, Metal Clad and MCI-A/Flex, so MC or AC lands straight in the clamp with no additional connector at the box. Three 1/2 in. knockouts give you the entry points. If you are pulling NM cable instead, this is not the box for it, the clamps are the AC/MC/Flex style.
3) Does the RACO 570RAC come with a mounting bracket for stud attachment?
No bracket is supplied. The 570RAC is the no-bracket version, so it mounts by screwing through the box into the stud or by nails through the side holes, and you supply the fasteners. It does have plaster ears for setting flush against plaster or drywall. If you need a box that sets its depth after the wall is up, the Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is a gangable 1-gang steel alternative.
4) Can I use a plastic switch box instead of the RACO 570RAC?
Only if your wiring method allows it. The RACO 570RAC is a steel box built for Armored Cable, Metal Clad, MCI-A and Flex wiring, with clamps sized for those cables. Non-metallic options such as the Allied Moulded P-181 FlexBox, an 18 cu. in. 1-gang thermoplastic switch/receptacle box, and the Cantex EZ20SB EZ Box 1-gang non-metallic box are intended for non-metallic cable work and do not provide the metal raceway continuity that AC/MC installations depend on. For AC/MC runs, stay with the steel 570RAC.
5) Is a 2-3/4 in. deep switch box too deep for a 2x4 stud wall?
No. At 2.75 in. deep the 570RAC still sits inside a nominal 2x4 stud wall, which gives 3-1/2 in. of stud depth. It is the deepest common single-gang steel switch box, chosen when you need the extra cubic capacity for multiple MC runs and a device. For furred-out walls or anywhere the cavity is shallower than 2-3/4 in. plus the box rear clearance, go with a shallower box.
6) Is the RACO 570RAC UL Listed for commercial device wiring?
The 570RAC is UL Listed. It is a steel switch box used for residential and commercial switch and receptacle wiring on AC, MC and flexible conduit systems, which is the common requirement where an inspector wants a metallic box and listed cable clamps in the same assembly.
7) Should I use a steel gangable box like the RACO 570RAC or a non-metallic box?
Pick the steel 570RAC when the wiring method is armored or metal clad cable, when the box has to be part of the metallic equipment ground path, or when you plan to gang boxes for a multi-device assembly. Non-metallic is the choice for NM cable work: the Allied Moulded P-181 FlexBox is an 18 cu. in. thermoplastic 1-gang residential box, and the Cantex EZ20SB EZ Box is a non-metallic 1-gang box made for steel stud framing.
8) Will plaster ears on the 570RAC work for a drywall remodel, or do I need an old work box?
The plaster ears set the box flush to the finished surface and give you a bearing point on plaster or drywall, but they are not a retaining device for an existing wall, the 570RAC still needs to be fastened to framing. For cut-in work where there is no accessible stud, use an old-work or wing-style box instead.
9) What should I use instead of the RACO 570RAC for a two-device opening?
Two routes. Because the 570RAC is gangable, you can join a second 570RAC to its side and build the 2-gang opening from two 3 in. x 2 in. steel boxes with AC/MC/Flex clamps. If you would rather set a single 2-gang body, the Allied Moulded 2302-NKV is a 2-gang electrical switch box in fiberglass reinforced construction - a one-piece non-metallic alternative rather than a ganged steel assembly, so it suits non-metallic cable rather than armored or metal clad runs.
10) Which box do I use for a steel stud wall instead of the RACO 570RAC?
The RACO 570RAC ships without a mounting bracket and relies on its plaster ears for a flush set in plaster and drywall, so it is typically fastened to wood framing or supported by other means. For steel stud framing the Cantex EZ20SB EZ Box is a 1-gang non-metallic box made specifically for steel studs. Note the trade-off: the EZ20SB is non-metallic, while the 570RAC is steel with integrated AC/MC/Flex clamps, so the choice is driven by your wiring method as much as the framing.
11) What is the RACO part number and UPC for the 2-3/4 in. deep gangable steel switch box?
The manufacturer part number is 570RAC, UPC 050169005705. That designation covers the 3 in. x 2 in. box at 2-3/4 in. deep, no bracket, with AC/MC/Flex clamps. Spec sheet is published by Hubbell under the same 570RAC number.
