Abstract: A branch circuit monitor is for a load panel inputting a number of line voltages and including a plurality of currents. The branch circuit monitor includes a processor component having a plurality of digital interfaces and is structured to receive a plurality of first digital values from each of the digital interfaces; and a plurality of metering mechanisms external to the processor component. Each of the metering mechanisms is structured to: communicate with a corresponding one of the digital interfaces, convert analog values from the number of line voltages and a plurality of the currents to a plurality of second digital values, determine a plurality of digital energy values from the second digital values, and transmit the second digital values and the digital energy values to the corresponding one of the digital interfaces.

Abstract: An energy monitoring system for a power conductor includes a base unit; a sensor cable; and a current sensor electrically connected to the base unit by the sensor cable. The base unit includes a first indicator circuit having a first indicator. The current sensor includes a second indicator. The first indicator circuit controls the first indicator and the second indicator to turn on simultaneously.
