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: A metering assembly includes an FT-21 kWh analog meter enclosure having an opening and carrying a plurality of stabs. A frame includes four sides, with the bottom side carrying a plurality of electrical terminals. The stabs electrically engage the frame terminals. A mechanism secures the frame within the enclosure opening. A display module includes a display port and a metering display driven from the display port. A monitoring module includes a monitoring unit, a display port driven by the monitoring unit, and a module enclosure having four sides. The monitoring module top side is mounted to the frame top side. The monitoring module bottom side has a plurality of electrical connections to the frame bottom side electrical terminals. The monitoring module display port is electrically connected to the display module display port. A mechanism mounts the display module to the frame offset from the monitoring module front side.
