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.
