ELECTRIC VEHICLE SUPPLY EQUIPMENT
First Claim
1. An electric vehicle supply circuit comprising:
- input wiring including a hot conductor and a neutral conductor to connect the electric vehicle supply circuit to a power source having a hot conductor and a neutral conductor;
a charge circuit interrupting device arranged to interrupt the flow of power from the input wiring to an electric vehicle; and
a controller coupled to the charge circuit interrupting device;
wherein the charge circuit interrupting device is constructed and arranged to disconnect the hot conductor and the neutral conductor in response to the controller.

Abstract
An electric vehicle supply circuit comprises input wiring including a hot conductor and a neutral conductor to connect the electric vehicle supply circuit to a power source having a hot conductor and a neutral conductor, and a charge circuit interrupting device arranged to disconnect the hot conductor and the neutral conductor if the power source is wired incorrectly. A monitor circuit may operate as a polarity detector if the power source is wired incorrectly, or as a grounding monitor circuit if the power source is wired correctly. Another electric vehicle supply circuit includes a monitor circuit to to detect whether a power source is wired correctly, and an indicator to communicate to a user whether hot and neutral conductors of the power source are wired correctly.
