ABSTRACT:
Disclosed herein is an apparatus for use in an AC power distribution system having a sinusoidal voltage source and a load, the apparatus including a circuit for selectively connecting and disconnecting the load from the source, a circuit for sensing voltage of the source, and a circuit for memorizing a characteristic of the source voltage, prior to the load being disconnected from the source, and for reconnecting the load to the source at a zero crossing point of the voltage sinusoid so that the sinusoid continues cycling in the direction it would have if the load had not been disconnected from the source.
