What is the primary purpose of a capacitor in an air conditioning system?
Correct!
Wrong!
Capacitors store electrical energy and provide the necessary start-up boost for motors in air conditioning systems.
Which component is used to protect an air conditioning system from overcurrent?
Correct!
Wrong!
Fuses or circuit breakers are designed to protect the electrical system by breaking the circuit if the current exceeds safe limits.
What is the role of the contactor in an air conditioning system?
Correct!
Wrong!
The contactor is an electrically controlled switch that connects or disconnects the power supply to the compressor and fan motors.
Which electrical safety device ensures that the system shuts off in case of an overload?
Correct!
Wrong!
Overload relays are critical safety devices that protect the system by shutting it off when an overload is detected.
What is the function of the thermostat in an air conditioning system?
Correct!
Wrong!
The thermostat senses indoor temperature and signals the system to start or stop cooling to maintain the desired comfort level.
Why is grounding important in air conditioning electrical systems?
Correct!
Wrong!
Grounding provides a safe path for electrical faults, reducing the risk of shock and protecting both the equipment and the user.
