Once you have the wattage and voltage, you can use Ohm's law to calculate the amperage. Ohm's law states that amperage is equal to the wattage divided by the voltage. For example, if your water heater is 4500 watts and operates at 240 volts, the amp rating would be approximately 18.75 amps (4500 watts ÷ 240 volts).

For example, a water heater that uses 20.83 amps will require a circuit breaker of at least 26.03 amps since 20.83 x 1.25 = 26.03. Common Breaker Sizes by Gallon. Most residential water heaters require a 30-amp circuit breaker. But if your water heater has a 90-gallon capacity or more, you might need a bigger one.

Attach the blue-coded fitting to the cold-water inlet with the arrow facing into the water heater. Attach the red fitting to the hot water outlet with the arrow pointing away from the water heater.
