Greg,

This will be my last post about this topic, but another EC got into it with me over the weekend at the supply house. "If you had a built in window seat, it is furniture, not usable wall space. So therefore a built in book case is also not usable wall space". He also said that if you have a wall in an exercise room and the HO puts mirrors on the wall, then the receptacle will be behind the mirror and not accessible. I didn't have my responses from this forum printed out yet, so I couldn't give them to him. I tried to explain that "Usable" wall space is not in the code. He then said that we should use more common sense when we write the NEC. I asked him if he ever wrote in a proposal to the NEC, and of course the answer was no.
