Where the supply power comes of aircon relay switch?
The supply power for an air conditioner relay switch typically comes from the main electrical panel of the building or home where the air conditioner is installed. The relay switch is connected to the power supply through a circuit breaker or fuse, which provides protection against overcurrent conditions. The circuit breaker or fuse is usually located near the air conditioner unit or in the main electrical panel. The power supply provides the necessary voltage and current to operate the relay switch and control the air conditioner's functions, such as turning the compressor on and off, regulating the fan speed, and adjusting the temperature settings.
