RACO RACO660 – Frequently Asked Questions
1) Will the RACO 660 handy box fit a standard single switch or receptacle?
Yes. The RACO 660 is a 4 x 2 inch handy box (also called a utility box) with a 1-7/8 inch deep interior, and it is built for mounting a single switch or receptacle. Note that a handy box takes a handy-box cover with the device opening, not a standard flat wall plate, so order the matching 4 x 2 utility cover for the device you are installing.
2) How does the RACO 660 mount if it has no bracket?
The 660 ships with no bracket, so it is fastened directly, typically screwed to the face or side of a stud, a block wall, or surface-mounted on exposed conduit runs. If you need a box that nails onto a stud face at a set depth for drywall, you want a bracketed box instead; this one relies on your own fasteners for positioning.
3) How many conduit entries does the RACO 660 have?
Ten 1/2 inch knockouts are distributed around the box, so you can bring EMT or cable connectors in from the ends, sides, or back without repositioning the box. That matters on junction points where two or three runs land in the same enclosure.
4) What does drawn steel mean on a handy box, and is it better than a welded box?
Drawn means the body is formed from one piece of steel with no welded seam, so wall thickness stays consistent and the corners cannot split open at a weld when the box is struck or pulled on. The RACO 660 is a drawn box. Welded boxes are assembled from separate pieces; for device boxes in rough-in work the practical difference is seam integrity and a smoother interior that is easier on conductor insulation.
5) Does the RACO 660 handy box have a ground screw provision?
It has a raised ground provision built into the box for bonding the device and equipment grounding conductors, so you are not hunting for a tapped hole or adding a clip.
6) Is the RACO 660 acceptable for commercial work or just residential?
The 660 is UL Listed and intended for residential and light commercial wiring, including new construction rough-in, retrofit box replacement, and device mounting. For heavier industrial or wet-location work you would move to a cast or raintight enclosure rather than a drawn steel handy box.
7) What part number do I order for the RACO 660, and where are the full specs?
Order it as RACO 660. The manufacturer's spec sheet is published at https://hubbellcdn.com/specsheet/RACO-660-SPEC-EN.pdf if you need the sheet for a submittal package.
