What happens when a circuit breaker trips?

• A. It increases the current flow
• B. It interrupts the flow of electricity
• C. It boosts the system voltage
• D. It modifies the amperage

Answer: (B)

When a circuit breaker trips, it interrupts the flow of electricity. This action is a safety mechanism designed to protect electrical systems and prevent damage from overcurrent conditions, such as short circuits or overloads. By tripping, the circuit breaker opens the circuit, effectively stopping the flow of current and preventing potential hazards like electrical fires or equipment damage. The purpose of a circuit breaker is to maintain safe operational limits within an electrical system. When the current exceeds those limits, the breaker automatically disconnects the power, ensuring that the system remains safe and functional. This interruption is crucial in maintaining the integrity of electrical components and protecting them from excessive heat and damage that could occur if the current were allowed to continue flowing unchecked.
