I have a scale that has to be installed in a industrial blg. It is 120v, 25a, single phase, 100ft. away from panel. The NEC states that this circuit requires a 6ga THHN wires for this. My boss says this will never pull that much amperage. Am I right in what I want to do or do I do what he says which is wrong in my opinion? He wants me to put a 10ga wire on this.
