What size wire should be use to connect a dryer?

The minimum recommended wire size for clothes dryer circuits is 10 gauge. However, amperage decreases over distance, so appliance manufacturers advise a larger wire gauge for circuits that extend beyond a distance from their source. In general, a circuit that runs 15 feet to reach the dryer requires larger wire, usually 8 gauge.
