Some large heaters draw up to 50 amps requiring 6 gauge wire.

Electric water heater wire connection.

The two poles means it is a stated 240 volts or an actual 230 volts. Most home hot water heaters are powered by a 240 volt circuit. At the water heater the black circuit wire connects to the black wire. Understanding water heater wiring.

These thermostat we used for controlling the water heater element. The ground wire is attached to the green ground screw which is in the same wiring junction box compartment which is built into the top of the water heater.

The white wire is the hot wire. It is extremely important that the circuit be off when wiring an electric water heater. Understanding electric water heater wiring. The circuit wiring typically includes a 30 amp double pole breaker and 10 2 non metallic nm or mc cable.

In cases where you are replacing a gas tank with an electric you will likely need to run cable 2 pole 30 amp breaker with 10 2nm cable from the circuit to the tank. Wire a hot water heater with wire that s sized to accommodate the heater s current requirement. For example a 20 amp hot water heater needs 12 gauge wire a 25 amp hot water heater requires 10 gauge wire and a 30 to 40 amp hot water heater requires 8 gauge wire. Many of the older 30 amp 240 volt dedicated water heater circuits consisted of a 2 wire with ground cable which consisted of a ground wire a black wire and a white wire and in these circuits the white wire was normally connected to the red wire of a 240 volt water heater however as described in the preceding the circuit must be.

Electric water heaters require a 240 volt dedicated circuit which serves only the water heater and no other appliances or devices. Before you get started you need to ask yourself is power currently running to the water heater s location.
