Abstract

Certain exemplary embodiments comprise an electrical power distribution panel, which can comprise a Source Line Evaluation Detector. The Source Line Evaluation Detector can be configured to open a contactor responsive to at least one condition from a plurality of monitored electrical source line conditions. The Source Line Evaluation Detector can be configured to monitor the one or more monitored electrical source line conditions.

Claims (44)

1. A system comprising:

an electrical power distribution panel comprising a Source Line Evaluation Detector, said Source Line Evaluation Detector configured to open a three pole contactor responsive to at least one condition from a plurality of monitored electrical source line conditions, said plurality of monitored electrical source line conditions comprising:
