Abstract: Disclosed is a device for monitoring an electrical power flow between a power source and a load. The monitoring device includes a monitoring module configured to monitor one or more aspects of the electrical power flow, the monitoring module configured to detect a fault condition when one or more aspects fall outside a predetermined operating range. In addition, the device includes a protection module configured to interrupt the electrical power flow upon detection of the fault condition. In some embodiments, the monitoring device includes a reset module configured to re-establish electrical power flow between the power source and the load. In some embodiments, the monitoring device further includes a diagnostic module configured to determine diagnostic information based at least in part on one or more of the monitored aspects of the electrical power flow.
