Abstract
Apparatus for remotely controlling electrical equipment includes a ground fault interrupter circuit having a selectively operable circuit breaker for connecting and disconnecting power to the electrical equipment, a transmitter for generating amplitude modulated electromagnetic radiation when it is desired to operate the circuit breaker, and a receiver responsive to the electromagnetic radiation for selectively operating the circuit breaker.
Claims29
Apparatus for remotely controlling electrical equipment including an electrical load and power lines for connecting the load to a power supply, said apparatus comprising:
- a) a first switch for connection in the power lines and operable between open and closed positions to control power to the load;
- b) a second switch connected to control operation of said first switch;
- c) a ground fault interrupter circuit connected to control operation of said second switch;
- d) a third switch connected to control operation of said first switch;
- and
- e) radiation signal responsive means for controlling said third switch.
Apparatus for remotely controlling electrical equipment, which comprises:
- a ground fault interrupter circuit having first means selectively operable for connecting and disconnecting a source of power to the electrical equipment;
- and
- second means responsive to electromagnetic radiation for selectively operating said first means.
