How Do You Wire A 220-Volt Baseboard Heater?
Electric baseboard heaters provide heat off of a 220V circuit. In this type of circuit, the neutral lead from the breaker box is replaced by a second hot lead, creating a circuit that carries twice the voltage of a typical 110V circuit at the same current. This results in a greater power output without raising energy costs. The extra power is useful for baseboard heaters as well as other home appliances such as ovens and water heaters. Though the circuit carries a different voltage, the wiring still consists of three leads including a ground; it is no more difficult than wiring any standard household appliance. Disable power at the breaker box, and run a 12/2 three-strand NM cable from an available two-pole, 30 amp breaker to the location of the baseboard heater. If you do not have an available breaker that meets these requirements, you will need to install one in order to create a 220V circuit. If you are unsure of how to install a circuit or run the proper cabling, consult an electri
