A 12" deep panel is flush mounted in a 8" block wall (Question #1: Allowed?). In the opposing room, there are (2) 6" conduits mounted to strut that has been fastened to the rear 4" of the panel that is sticking out of the wall, which leads to Q2, is mounting the strut to the back of the panel allowed? I found no such information on panels that stick through walls in the NEC, except possibly not a neat and workmanlike installation (110.12).
Thank you. John Kreider
