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.
3. Requires minimum 150 A main service.
4. Requires 200 A main service.
5. Requires 300 A main service.
6. 29 Trend/Plus & 36 Trend/Plus may be wired for balanced 3-phase 208 V. 15 Trend/Plus, 20 Trend/Plus, 24 Trend/Plus may be wired for unbalanced 3-phase 208 V
