for metal studs which type of electrical device box use?

Michael Thomas

Boxes designed specifically for attachment to metal studs have a special purpose fastener on the side, the "C-grips" are also available as a separate component.

:steel studs do not require any specific type of boxes. I nmy line of work, we generally use a Raco 192 or 232 and Caddy brackets

here are a few Caddy brackets:

if this is commercial work, you are at the wrong forum. There is a pro forum at http://www.electriciantalk.com/

I agree. Something is fishy here.



As you know, that site is for professionals only, and this cat ain't no professional I assure you.

I know

For this type of building the safest way to deal is get a qualifed electrician to come out and deal with it due there are a bit of codes to cover and Hi rise building electrical system is not a DIY at all per majorty of state code.

{ I have the excat the same codes in France as I mention above so there is no diffrence at all }


Merci.
