RACO RACO519 – Frequently Asked Questions
1) Can the RACO 519 switch box be ganged together for a 2-gang or 3-gang device install?
Yes. The 519 has removable sides, so two or more boxes join to build multi-gang assemblies for stacked switches or receptacles. If you would rather set a single moulded box for a two-device opening, the Allied Moulded 2302-NKV is a one-piece fiberglass 2-gang box instead.
2) What cable type do the clamps in the RACO 519 accept?
The 519 ships with factory-installed clamps for nonmetallic sheathed cable (NMSC, commonly Romex). That is the wiring system the box is built around, so you do not need separate connectors for NM runs. For armored cable or conduit work, pick a box set up for that method instead.
3) Does the RACO 519 come with a mounting bracket for stud attachment?
No bracket. The 519 ships bare, so you fasten it to the stud through the side holes with nails or screws, or mount it however the framing allows. If you want a box that lands at the right depth off a bracket, the Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is a gangable steel alternative with an adjustable body, and the Cantex EZ20SB is built for steel stud framing.
4) What is the closest steel gangable alternative to the RACO 519 switch box?
The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is the nearest match in material and construction: it is a 1-gang gangable switch box in pre-galvanized steel, so like the RACO 519 it has removable sides that let boxes be joined for multi-device assemblies. The RACO 519 is a 3 in. x 2 in. steel box with a 2-1/2 in. deep interior, one 1/2 in. knockout, factory NMSC clamps and plaster ears, and is UL Listed. The Adjust-A-Box differs in that it is an adjustable-depth design, so it is positioned relative to the finished wall after the stud is set rather than fixed at one depth.
5) Should I use a nonmetallic box instead of the RACO 519 for residential rough-in?
Both routes work for nonmetallic sheathed cable rough-in. The RACO 519 is a steel device box with built-in NMSC clamps, plaster ears, and a 2-1/2 in. deep interior, and it grounds through the metal raceway/box system. If you prefer a nonmetallic box, the Allied Moulded P-181 FlexBox is a 1-gang thermoplastic switch/receptacle box rated 18 cu. in. for residential work, and the Allied Moulded 2302-NKV is a 2-gang fiberglass reinforced switch box. Choose steel where you want the gangable sides and clamp-equipped metal body; choose the thermoplastic or fiberglass boxes where a non-conductive enclosure is wanted.
6) Will the RACO 519 sit flush with drywall?
It has integrated plaster ears, which let you set the box face against the finished wall surface so the device plate sits flat. Since there is no bracket, you control the setback yourself when you nail it to the stud, so set it for your drywall thickness during rough-in.
7) Steel gangable box or a plastic one-gang box for residential rough-in?
The RACO 519 is a steel box with removable sides, so it is the choice when you may need to gang devices or want a metal enclosure. A one-piece nonmetallic box like the Allied Moulded P-181 FlexBox, an 18 cubic inch thermoplastic switch/receptacle box, is the simpler option for a fixed single-gang opening with no bonding of the box required.
8) What should I use instead of the RACO 519 in a steel stud wall?
The Cantex EZ20SB EZ Box is a 1-gang non-metallic box made specifically for steel stud framing, so it attaches to the stud without a separate bracket. The RACO 519 ships with no bracket, which keeps mounting methods flexible but means you supply the attachment method for the framing you are working in. For metal-stud partitions where you want a box that fastens directly to the stud, the EZ20SB addresses that; for wood framing and multi-gang assemblies, the gangable steel 519 is the usual choice.
9) If I need a two-device box, do I gang two RACO 519 boxes or buy a 2-gang box?
Either approach gets you two devices. The RACO 519 has removable sides so two boxes can be joined into a 2-gang assembly, which is handy when you decide the device count at rough-in. If you would rather set a single one-piece enclosure, the Allied Moulded 2302-NKV is a factory 2-gang switch box in fiberglass reinforced construction. Ganging 519s keeps the installation in steel with NMSC clamps already fitted; the 2302-NKV is one nonmetallic body with no gang seams.
10) Is the Steel City Adjust-A-Box a drop-in replacement for a RACO 519 already in the wall?
Not exactly. The Thomas & Betts LXWOWC-25 is also a 1-gang gangable steel switch box, but it is an Adjust-A-Box design, meaning its depth position is adjusted at install rather than fixed. The RACO 519 is a fixed 2-1/2 in. deep box with integrated plaster ears for flush mounting to the finished surface. For a straight swap in an existing opening, match the fixed-depth steel box; the Adjust-A-Box is better suited to new rough-in where wall thickness is still being set.
11) How many wiring entries does the RACO 519 have besides the cable clamps?
One 1/2 inch knockout, which takes a standard 1/2 inch trade size connector if you need to bring in something other than NM cable through the built-in clamps.
12) What is the manufacturer part number for the RACO 2-1/2 inch deep gangable switch box?
RACO 519. That is the part number to order against, and it is the steel 3 x 2 gangable device box at 2-1/2 inch depth with NMSC clamps.
