Also if you can put the panel into the pantry closet, aside from the clothing what is the differance.

With the size of some of the closets I have seen "huge'' I don't think it should be prohibited if the closet is over a certain size. I worked on a house last year where the master closet was larger then the kids bedroom.

A closet is a closet, can't have your cake and eat it too... The other thing is I don't believe size is the reason you can't install a panel...

Had to edit this one,

Art. 240.24 (D) Overcurrent devices shall not be located in the vicinity of easily ignitible material, such as in clothes closets.

I'd guess that the inspector in the op would require fire terated studs on either side.

John, wouldn't that mean all the boxes would have to be attached to Fire resistant lumber as well?

When I first read this I tought you had put " Indigestible". In reference to the pantry.

Some time ago an EC in this area got his you-know-what in a sling because he was mounting panel boards on plywood onto concrete walls. The claim was that the plywood was flammable. I am not sure what the issue was exactly, maybe non-flammable materials required.

I gather that this was a common practice and was being passed by the inspectors.

Somehow he ended up getting additional scrutiny beyond what the other ECs got (I think I know why but it is not relevant) and ended up having to make a fair number of them non-flammable by painting them with some kind of coating. They even made him go back and redo a bunch of them that they had already passed, or so i was told.

Yes, fire treated plywood is required in many commercial buildings, but for an inspector to carry that over to a residential building is crazy.

The old green treated wood didn't need special fasteners, but the new "arsenic free" stuff (often called AC2) does. I have heard of it eating through standard bolts in a year (but that could be a big fish type tale). I think you have to use either stainless or coated fasteners.

Treated lumber is not necessarily fire resistant. The stuff that is treated for rot and insect resistance will burn quite readily.

My understanding is that stainless or plated fasteners were always required in either the old or new style treated lumber. At least so said Norm.
 
many years ago a co worker told me you cant put a panel or a light switch in a clothes closet because the dry cleaning chemical is flamable. but you could put a switch on the out side wall of a closet.

That was my point in my first response to this thread. I think the idea of using fire treated lumber for an electrical panel is absurd, and I was trying to convey that.

If your not using pressure treated 2x4's, whats the difference between mounting plywood to the concrete vs untreated 2x4's?

My issue isn't with pressure treated lumber. I personally just don't like a piece of plywood nailed to the concrete. I like the way the 2x spacing allows you to run cables behind the plywood to be brought into the bottom of the panel. And for running tel. catv, and alarm cables behind the board and then through the plywood.
 
We often will get the carpenters to build a small wall 6-8" away from the wall in an unfinished basement for the service. That not only allows wires to run behind it, but insulation as well.

That is nice but will there be insulation where you have all those cables bunched behind the panel? I have not seen that done in already 20 years. there are overheating cable problems but also vapour barrier sealing problems.
I do the same but no cables behind only beside the panel.
