Abstract

A module for an electrical distribution system is provided. The module includes a socket board electrically coupled to the electrical distribution system. A plurality of sockets is mounted on the socket board. Each socket defines a port. A sensor is positioned within each port and is electrically coupled to the socket board. The sensors are configured to carry at least one of a primary current and a secondary current. A metering component is electrically coupled to the socket board and configured to measure current carried by the sensors. A communication module is electrically coupled to the metering component and in communication with a monitoring device. The communication module is configured to transmit metering data to the monitoring device.
