Notes on Tables 18 through20.
1. Nominal input current (considered continuous) is based on full rated output load maximum current includes nominal input
current and maximum battery recharge current (considered noncontinuous). Continuous and noncontinuous current are
defined in NEC 100. Recommended overcurrent protection is based on 80% rated devices.
*The recommended overcurrent protection represents 125% of nominal full load current (continuous) per NEC 215.
2. Maximum input current is controlled by the current limit setting.
3. Recommended AC input external overcurrent protection is based on 80% rated devices and maximum input current limit
setting.
4. Recommended AC output external overcurrent protection is based on 80% rated devices and full rated output current.
5. Nominal battery voltage is shown at 2 volts per cell.
6. Input power factor of 0.99 is used for the calculations.
