*DHC-E 8/10 is a single unit that is switchable at installation via jumper for output at 7.2 kW (Stage 1) or 9.6 kW (Stage 2).
1
Overcurrent protection sized at 100% of load. Tankless water heaters are considered a non-continuous load.
2
Copper conductors with a temperature rating of 75 °C or greater must be used. Conductors should be sized to maintain
a voltage drop of less than 3% under load.
These are our recommendations. Check local codes for compliance if necessary.
