A contractor recently remodelled our master bathroom, and ran a dedicated “20A” circuit as required (by Broan) for the new bathroom heater / vent / fan combo unit. He installed a 20A breaker, but ran 14 gauge wire.
The Broan model has a 1500watt heater element, but says total draw is 14amps. Regardless of the fact that this is a dedicated circuit within the current capacity of 14 gauge wires, this really is unacceptable to put 14 gauge on a 20A breaker, right? Total run length from breaker panel is about 70 feet.
Recommendations, please? Should I require the wire to be replaced with 12 gauge?
