A circuit breaker will shut off the energy supply with excessive voltage. It may be due to high-voltage appliances or power surges in the electricity supply. There may also be a matter with the low voltage wire if your air conditioner is not turning on. This line helps transport electricity from the home's electrical system to the air conditioning equipment. If it becomes damaged or disconnected, the machine may be unable to start.
