Commonly Used Telecom Power Cable Sizing Table

Legend:

Conductor Size (mm) = Size of power cables being used  (Refer to the cable sizing table below)

Voltage Drop (V) = Change in voltage from batteries to charger

Amperage Capacity (A) = The highest amount of amps that will be flowing through the power cables

Loop Distance (ft) =  distance of power cables from batteries to charger (power plant)
