A power distribution apparatus for distributing electrical power includes circuit breaker modules and remote operated devices mounted separately in a panel. The devices may be relays, circuit breakers, meters, dimmers or other devices for controlling a circuit. An I/O controller board is connected to the remote operated devices and controls those devices through a data rail. A control module may interface with the I/O controller board and may also interface with other I/O controller boards and with one or more networks. The I/O controller board is mounted in the subfeed breaker region of the panelboard, at an end of the panelboard opposite the main breaker region. The controller board may include connection and status features that are accessible through the deadfront.
