T here you go in plain english. Get the local wiring inspector if available. If not get a state inspector. This is wrong, wrong, wrong. Someone either was a moron or just trying to save a few bucks at your expense. This is not acceptable, it is not legal, it is not safe, and it is what gives all of us good electricians a bad name. I also wonder if the builder is aware of what his electrician is up to. I would most certainly let him know.
