Dual Pole electrical cables

Dual Pole electrical cables from Phillips Industries solve grounding problems caused by heavy amp-draw accessories on trailer equipment, such as liftgates. With common single pole connectors the ground return path can be obstructed at the fifth wheel, causing power to flow through the white wire in the 7-way connector. This condition overloads the wire, leaving no power for the trailer lights or ABS or potentially causing permanent damage to the electrical system.
