1
This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.
Tankless water heaters are considered a non-continuous load.
2
Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
3
Suitable for supply with cold water only.
