Nominal mains voltage is 110-120V and 220-240V.
2
This is our recommendation for over-current protection sized at 100% of load. Check local codes for compliance if necessary. Tankless water heaters are considered a
non-continuous load.
3
AWG copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
