1
Nominal mains voltage is 110–120 V and 220–240 V.
2
This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.
Tankless water heater are considered a non-continuous load.
3
Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
4
For use with cold water supply only.
