Joey:
As far as I know, the EC's around here do the putty pads/fire blanket thing. There's a 19 bldg apt complex going up, and the EC is doing the putty pad thing. There is supposed to be a 'rated box', but I have not seen it yet.
Careful layout avoids the multiple boxes in the same bay.....they need a minimum 24" spacing to the best of my knowledge.
