Abstract

A load control arrangement includes a communication channel configured to transmit information. A controller unit is coupled to the communication channel and configured to at least one of send and receive information via the communication channel. A load control device is coupled to the communication channel, comprising a disconnect switch configured to be coupled to a power line. The load control device is further configured to determine a power consumption of a load connected to the power line. The load control device provides measurement data representing the determined power consumption via the communication channel to the controller unit. The load control device drives the disconnect switch depending on drive information received via the communication channel or depending on the determined power consumption.
