RACO RACO248 – Frequently Asked Questions

1) Do I need separate MC cable connectors with the RACO 248 box?
No. The RACO 248 has AC/MC/Flex clamps built into the box, so Armored Cable, Metal Clad, MCI-A and Flex land directly in the box without buying separate connectors. That is the main reason electricians spec it over a plain box with open knockouts, and it cuts both parts count and install time on branch circuit rough-in.
2) Does the RACO 248 come with a mounting bracket?
No bracket. The 248 ships as a bare welded box, so you mount it with your own hardware, through the back or side holes to a stud, strut, or surface. If you want a box that nails straight to a stud face at a fixed setback, you need a bracketed 4 square instead.
3) Will the RACO 248 accept NM (Romex) cable?
The clamps in the 248 are AC/MC/Flex clamps, intended for Armored Cable, Metal Clad, MCI-A and Flex. If your job is NM cable, look for a 4 square with NM/loom clamps or use a listed NM connector in one of the knockouts rather than relying on these clamps.
4) Is the RACO 248 box approved for commercial work?
It is UL Listed, which is what inspectors look for on a metallic outlet and junction box in commercial and residential branch circuit wiring. Typical uses are junction boxes for branch circuits and AC/MC/Flex cable installs in new construction and remodels.
5) What is the difference between a welded and a drawn 4 in. square steel box?
The RACO 248 is welded, not drawn. A drawn box is formed from one piece of steel; a welded box is formed and seam welded, which gives a stiffer body that holds its shape when you are pulling MC into it or torquing mounting screws. Either style wires the same way, so the choice comes down to the clamps and depth you need rather than the forming method.
6) Where can I get the RACO 248 spec sheet for a submittal?
RACO publishes a spec sheet for the 248 at hubbellcdn.com/specsheet/RACO-248-SPEC-EN.pdf, which is what to attach for a submittal package. Order by manufacturer part number 248.
