Is my configuration up to code?
I have mounted a 200 amp panel in an unfinished block basement. The ceiling is 9 feet high. The panel is surfaced mounted to a 4 x 8 x 3/4 pressure treated plywood screwed to the block wall. It is 72 inches from floor to the main breaker. All of the romex wire is leaving the top of the panel and is stapled to the plywood, except a GFCI receptacle mounted on the right side of the panel with an offset nipple. The load of the GFCI receptacle is romex going up along side the panel and is stapled on the plywood. Is having romex surfaced mounted to plywood in an unfinished basement legal?
