We'll install 800A main breakers , meters and other heavy panels on a metal frame wall. We plan to put 5/8 sheets of plywood up first to make the wall
stronger. Can we use any plywood or can we use combustible material at all?
Thanks for any help , Dan
 
Around here they make us use fireproof paint... not exactly sure why though...:grin: seeing I can recess a panel between 2x4's and nobody has an issue with it...
 
"Strut Feet" and strut attached to the wall. If you can think it, I can strut it.
 
I'm with Rocky, a large panel should be hung on strut that's sitting on the floor. This puts a large portion of the weight on the floor with the wall only supporting the tip weight.

Wouldn't the studs of the wall do the same thing? Transfer the weight to the floor?
 
It depends on the type of construction. If it is type I or II, your wood would have to be fire treated. If it is types III, IV or V, it does not need to be treated.
 
If the wall needs to be fire-rated, why not install the plywood directly on the studs, then let the sheetrockers cover it with fire-rated rock?
