Table 2 lists the a.c. input and the d.c. output minimum wire size requirements. At distances
exceeding 10 feet, the d.c. wire size should be chosen to keep the voltage difference between the
units d.c. output terminals and the battery at less than ½ volt when the unit is fully loaded. See
Section 7.6 for “POWER CABLING FORMULAS”. The total loop length is twice the distance from the
wiring point to the unit.
