1. Turn off the Power at the main breaker.
2. Take each wire pair and connect them to one breaker. Ensure each breaker is connected with one black wire and one red wire.
3. Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers used, run the correct sets of wire from the main breaker panel to the tankless water heater.
4. A separate ground conductor is required.
5. Double-check the electrical connections to make sure they are correct and that all wire connections are tight and secure.
