ABSTRACT:
An independent automatic shedding system that automatically allows any combination of loads to powered under limited power availability (such as a standby power source) without overloading the generator or rewiring, while contributing to the stability of the power grid. A motorized disconnection actuation mechanism under control of a controller disconnects or recloses the contacts of a branch circuit breaker. A sensor detects the presence or absence of a power source and the type of power source, which is classified according to its type. A power source classification program is executed by the controller that interprets the sensor data and causes disconnection or reclosing of the disconnection actuation mechanism depending on a desired status (ON or OFF) of the branch circuit breaker when standby power is available. Conventional circuit protection is provided an optional advanced circuit protection such as ground or arc fault circuit interruption.
