INSTALLERS INFORMATION
The table below lists the AC and the DC minimum wire size requirements. At distances exceeding
10 feet, the DC wire size should be chosen to keep the voltage difference between the unit's
terminals and the battery at less than 1/2 volt when the unit is fully loaded. If the distance
between the unit and the battery exceeds 10 feet, use the Power Cabling Formulas to determine
wire size.
