*Maximum drop line current depends upon the length of the drop. See below.
Current limits for drop lines are shown in Table below and described by the following equations:
1= 15/L
where I is
the allowable drop line current in amps and L is the drop length in feet, or:
I=4.57/L
where
I
is the allowable drop line current in amps and L is the drop length in meters.
