Major appliances like washers and dryers call for special wiring and receptacle outlets, to operate safely and efficiently. For these big machines, a 240-volt circuit is required, and is usually run with number eight wire, or even number six wire. Remember, in wire sizing, smaller numbers mean larger wire. If in doubt, consult the nameplate marking on the appliance. Code states that a dedicated 20-amp branch circuit be wired to the laundry room equipment, in addition to at least one receptacle outlet. Although the laundry room is a wet location, ground-fault protection outlets are not required here. The electric clothes dryer must operate both a motor and heater at the same time, so it demands even more power than the washer. Therefore, the dryer must have its own separate circuit. Electric dryers can be hooked up in several ways, depending on your local code. For more information on the proper way to wire a laundry room, consult an electrical expert.
