ECN Forum Forums Code Related Discussion NEC & other Code issues Electrical Panel In One Hour Rated Wall

I have not found anything in our building code or in the UL direstory for fire resistance that allows for panelboards in fire resistive construction.

Rodger's method of "five siding" is commonly accepted, but is not backed up by any tested assembly I've seen.

If anybody has a UL classified (or equal) assembly for this I would really like to see it.
