I find this discussion interesting in that it makes me wonder if a job I encountered some months back should have been rejected. In between the time the inspector approved the rough in of an addition the homeowner decided he wanted the receptacles lowered since now he was going to install tile 12 inches up the wall and the receptacles would have been partially out of the tile area. So, without notifying us he cut the nails holding the one gang plastic boxes to the studs and we came at finish to find the boxes dangling behind the drywall. Although we should have said "enough of this" and walked, we proceded to put drywall screws through the side of the boxes into the studs. The cables just barely made it into the boxes. Should this have been a violation and the customer made to open the walls?
iwire, I hope I am not taking attention from your question because it seems related but this is important to me since we are scheduled to take this customer to court next month to collect funds we feel he owes us for tampering with our wiring.
I myself have anchored boxes using methods id'd in 1, 2 and 3 and never rejected. I find this interesting.
Thanks
