Abstract: A trip bar cam unit for a trip bar is provided. The trip bar cam unit includes a trip bar cam unit body, a cam lever, and a keyed protrusion. The trip bar cam unit body defines an axis of rotation. The cam lever extends generally radially from the trip bar cam unit body. The keyed protrusion corresponds to a trip bar axial bore.

Abstract: An electrical circuit for electric vehicle supply equipment including a pilot control signal unit structured to generate a pilot control signal having a state including one of a high state and a low state, a pilot control signal isolation unit structured to generate an isolated pilot control signal that is isolated from the power lines of the electric vehicle supply equipment and is based on the state of the pilot control signal, and an amplification unit structured to generate a pilot signal based on the state of the pilot control signal. The amplification unit is structured to receive the isolated pilot control signal and the isolated voltage and to use the isolated pilot control signal and the isolated voltage to generate the pilot signal, and the pilot signal is isolated from the power lines of the electric vehicle supply equipment.
