PROBLEM TO BE SOLVED: To provide an AC 100-volt power receptacle for detecting a load current flowing in a load electrical appliance connected to an "interlocked power receptacle" and interlocked to an operation of a load. SOLUTION: A full-wave rectifier 4 generates a direct-current potential from the load current in the AC power receptacle 3. The direct-current potential makes a solid state relay kit 11 actuate and supplies an AC 100-volt power to an AC receptacle 1. When the load current in the AC power receptacle 3 is small, a circuit structure is provided with a full-wave rectifier 5 to generate a "base potential" to form a circuit structure compensating for an operation. The "base potential" is synthesized with the direct current potential generated by a current detected by a current detection transformer 16, and is applied between positive and negative terminals of the solid state relay kit 11. An effect of the direct current potential synthesis assures functions of the "interlocked power outlet" to operate, even when an appliance with a relatively small load power of approximately 10 watts is connected to the AC power receptacle 3.
