* Nominal (List 1) current drains used to size batteries and rectifiers. To size batteries and rectifiers, use twice the
nominal (List 1) current drain per feeder. These current drains represent the average busy-hour current at normal
operating voltages.
†Maximum (List 2) current drains used to size each feeder cable and fuse. To size feeder cables and fuses, use
the maximum (List 2) current drain per feeder. These current drains represent the peak current under worst-case
operating conditions. Normally the current for the system is shared equally by both feeders.If one feeder fails, the
other feeder carries the total load for both feeders (feeder A + feeder B current).
