What device switches to interrupt overloaded circuits?

• A. Fuse
• B. Anode
• C. Circuit Breaker
• D. Grounding

Answer: (C)

When circuits experience too much current, the protective device that actively stops the power is the circuit breaker. It detects the overload and trips, opening the circuit so electricity is cut off and a fire or damage is prevented. You can reset a circuit breaker after the fault is cleared, which is convenient for ongoing use. By contrast, a fuse also protects against overload but does so by the metal link melting and breaking the circuit permanently, so it must be replaced after it blows. Grounding provides a safe path for fault currents to earth, reducing shock risk, but it doesn’t switch off an overloaded circuit. An anode is an electrode, not a protective switching device.
