Notes:

1.Nominal (Nom) Input current based on rated load.

2.Maximum (Max:) Input current based on full battery recharge + nominal load.

3.Recommendation: Input and Output cables run in separate conduits.

4.Suggested Input overcurrent protection based on continuous full load

Maximum Input current. Suggested Load Side Overcurrent Protection based on Nominal current. Breakers sized per NEC 220-3 and NEC 240-3(b). 80% rated breakers assumed. Trip rating based on

NEC 240-6(a) standard breaker sizes.

5.Nominal battery voltage assumed to be 2.0 volts/cell (lead technology).

6.Recommendation: All cables should be sized in accordance with NEC 210-19 FPN No. 4 branch feeder voltage drop of 3%. Voltage drop not considered in above chart. Application
