Prior to ABS requirements, the number 7 (blue) wire conductor was sized 12 AWG. This circuit was intended for “auxiliary” purposes.With ABS as law, DOT specified that
the blue auxiliary circuit shall also be used for continuous power for ABS and the size was changed from 12 to 10 AWG.However, many auxiliary devices plus the demands of
the ABS have caused some trucks to experience overheating due to over-loading the amp capacity of the auxiliary blue wire conductor as well as the ground white wire
One of the purposes of the Stallion Power 7 way socket is to give the industry the option of choosing a larger auxiliary blue conductor and a larger ground white conductor that will eliminate the over-loading and heating problem.
The chart at the left shows the Industry’s maximum wire sizes vs. Stallion’s maximum wire sizes for the auxiliary/ABS and ground wires.
The Stallion 7 way socket is interchangeable and works with all standard SAE 560b plugs.
