A circuit breaker protects an electrical circuit from damage caused by overcurrent or short circuit by interrupting the flow of electricity.
Which type of lighting is most energy-efficient for commercial buildings?
Correct!
Wrong!
LED lighting uses significantly less energy than traditional lighting sources and has a longer lifespan, making it ideal for commercial use.
What device measures the amount of electrical energy consumed?
Correct!
Wrong!
An electric meter tracks the amount of electrical energy used over time, typically in kilowatt-hours (kWh).
What is the purpose of using motion sensors in lighting systems?
Correct!

Motion sensors help save energy by automatically turning lights on when movement is detected and off when the space is unoccupied.
Which term refers to the rate at which electrical energy is used?
Correct!
Wrong!
Power is the rate at which energy is consumed, measured in watts or kilowatts.
Why is it important to balance electrical loads in a facility?
