How can you determine if a circuit is overloaded?

• A. By the age of wiring
• B. By checking the wattage of devices
• C. By monitoring for frequently tripping circuit breakers
• D. By inspecting wire insulation for damage

Answer: (C)

To determine if a circuit is overloaded, monitoring for frequently tripping circuit breakers is a reliable method. When a circuit is overloaded, it exceeds its designated capacity, which can lead to overheating and potential fire hazards. Circuit breakers are designed to automatically trip and cut off the current when they detect that the electrical load exceeds safe limits. Therefore, if a breaker repeatedly trips, it is a clear indicator that the circuit is drawing more power than it can handle, signaling an overload condition. In contrast, while checking the wattage of devices or inspecting wire insulation may provide insight into a circuit's capacity or condition, they do not directly indicate whether the circuit is overloaded in real-time. The age of wiring could suggest potential issues but isn't a definitive measure of overload. Monitoring circuit breakers gives a clear and immediate indication of whether a circuit is overloaded, making it the most effective approach.
