Webclear that the wire-break fault is indistinguishable from the sensor’s off state. Hence, this circuit cannot detect a wire break. Similarly, if the output of the digital-input module is stuck high or low due to a fault or defect in the internal circuitry of the optocoupler, the fault goes undetected. Proposed solution for wire-break detection and WebBender's RCMB level 2 ground fault sensing devices monitor circuits effectively for fault currents that can pose hazards to personnel and equipment. These leakage devices are listed to UL2231 and fulfill all the stringent safety requirements. They will trigger at either 5 or 20mA of potential hazard current and interrupt the EVSE.
