ABSTRACT:
A control apparatus for a plurality of devices, especially circuit breakers. The control apparatus includes activation circuitry for each device, and a power supply for supplying electrical power to the activation circuitry. The control apparatus adds a respective electrical signature component to the supplied electrical power upon detection that a respective device has operated. The signature components allow analysis equipment to determine which device has operated by analysing the supplied electrical power.
