Abstract

In one implementation, the method for processor based automated testing of ground fault interrupt circuit for electric vehicle supply equipment is provided. In one implementation the method includes providing a simulated ground fault signal to a ground fault interrupt circuit and detecting at a processor that the ground fault interrupt circuit sensed the simulated ground fault signal. The method further includes commanding from the processor a utility power contactor to close while the ground fault interrupt circuit is disabling closing of the contactor and verifying the utility power contactor is not closed in response to commanding the utility power contactor to close.
