Abstract
PURPOSE: To raise the safety, by providing an automatic load changer not to simultaneously operate loads coupled to a first and a second plug receptacles.
CONSTITUTION: The automatic load changer 3 consisting of a current transformer CT, capacitors C1, C2, diodes D1, D2, a resistor R, a thyristor S, a relay Ry, a normally-closed relay contact r, etc. is provided not to simultaneously operate the loads coupled to the first and the second plug receptacles 1, 2. Thereby, a first and a second plugs are prevented from being turned on simultaneously. Even if the total rating of the loads coupled to the plug receptacles exceeds that of the tap, an over- rating current does not flow through the tape. The damage of the tap and the tripping of a circuit breaker are prevented. The operating property and the safety are raised.
