The output power cables must be large enough to prevent a total voltage drop exceeding 1% of
the rated output voltage between the power source and the load. Table 3-1 shows the AWG size
of the cables that may be used. Cable lengths must not exceed twenty-five (25) feet. For lengths
greater than 25 feet, calculate the voltage drop from the following formula:
2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP
