Now, why should the carpenter have to pay for what was clearly a mistake by the electrician who failed to consider the architectural plan and mounted the box too low?
That's not necessarily a fair comment. I have one of those on a job I'm doing now. The engineer spec'd 48 inches, even though the two outlets beside were at 44 inches. The GC said to leave it and his carpenter said to leave it. They cut the woodwork back to accommodate the outlet.
Even in the case of a switch too close to a wide door frame, the electrician gets a phone call before the frame goes on.
My question is "what kind of a carpenter covers half a switch box"?
