置。In a power line carrier system that superimposes a load control signal and an audio signal onto an indoor power line for load control and communication, a low-frequency tone signal with a transmission speed very close to that of the load control signal is used as the audio signal. 1. A load control device comprising means for superimposing and transmitting a tone signal, and a receiving means for recognizing that a telephone conversation is in progress by determining a tone signal as meaningless data in a load control demodulation circuit.
