Abstract
An improved plug-in power module for providing a controlled amount of electrical power to one or more remote lighting fixtures or other load is disclosed, the module being configured to sense a ground fault or other current imbalance at the load and, in response, both to trigger the module's circuit breaker to open and to report the occurrence of such a ground fault to a central location. The power module achieves these important functions without adding unduly to the module's complexity or size.
