💡 How do I calculate the correct wire gauge and breaker size for an 18kW electric tankless water heater installation?
Installing a high-demand 18kW unit requires dedicated electrical components to handle the massive current draw safely.
- You must run two separate 8 AWG copper hot wires along with a ground wire to meet the continuous load demand.
- The service panel needs two individual 40A double-pole circuit breakers rated for 240 volts to protect the heating elements.
- Maximum amp draw sits at 75 amperes when both heating blocks operate simultaneously under peak flow conditions.
- Always verify local codes allow the required conduit size and clearances before connecting the power supply cables.
