Question
**Quiz Question: Electrical Components** A device designed to open and close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent without damage to itself when properly applied within its rating is called a ______. **Select one:** - a. GFCI - b. circuit breaker - c. potentiometer - d. knife switch **Explanation:** This question tests knowledge of electrical devices that protect circuits. - **GFCI (Ground Fault Circuit Interrupter):** A device used to protect against electrical shock by breaking the circuit when a difference in currents is detected. - **Circuit Breaker:** Automatically opens in the event of an overload or short circuit to prevent damage or fire. This matches the question’s description. - **Potentiometer:** A variable resistor used to adjust voltage. - **Knife Switch:** A manual switch used to open or close circuits. The correct answer is likely **b. circuit breaker**.
