ABSTRACT:
An apparatus and method for monitoring and controlling a backup power source and one or more critical loads powered thereby is disclosed. The apparatus is constructed in the form of an electrical distribution panel that includes electronic systems for monitoring the current to the critical loads. In the event of an overcurrent condition on one or more critical load circuits, the system is able to disable power flow to the offending circuit so as to protect the remaining critical load circuits and the backup power source. The system is also provided with a means for communicating status information about the system to a remote user.
