ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics Why switches,panel should be mounted on wood?

Checked with the older guys at the shop.Seems they remember the 3/4" dry wall fire stop was dropped by the building code in 1989 like Sandro said.I have no idea what i was thinking obviously you need the plywood when you have all that stuff to put next to the panel loomex , doorbell xformer cable and phone.Generally we try to stay away from wood at our plant because it's a noncombustible building.It's not illegal just not ideal in our application.Also we take the CCS update course when the new code book comes out.You get two code books.One regular code book and another that rationalizes the the new rules.I have to say The ESA Continuing Care Service is the best idea they've ever had You always get the same inspector.And they seem to have an(we're in this together attitude)
cheers

Who is telling you that switches and panels should be mounted on fireproof wood when installed on a concrete surface? Also you write "should" instead of "must". That in itself may be indicative of why you can't find anything in the code book. I always install plywood behind residntial service panels to facilitate the strapping of the romex.

Most resi panels are 14.5" wide...the exact spacing between studs. By design, they're meant to be mounted directly to wood.
