What is the primary function of a circuit interrupter?

• A. To increase voltage in the system
• B. To disconnect power when a fault is detected
• C. To measure electrical flow
• D. To store electrical energy

Answer: (B)

The primary function of a circuit interrupter is to disconnect power when a fault is detected. This is essential for protecting both the electrical system and individuals from safety hazards. In the event of an overload, short circuit, or ground fault, the circuit interrupter automatically cuts off the electrical supply, preventing potential damage and reducing the risk of fire or electric shock. This mechanism is particularly important in ensuring the stability and safety of electrical installations, as it helps to maintain conditions that allow for the safe operation of electrical devices. The use of circuit interrupters is a fundamental practice in modern electrical systems, helping to ensure that faults are swiftly addressed to prevent further complications.
