Frequent tripping of circuit breakers is a strong indicator of an electrical overload within a system. Circuit breakers are designed to protect electrical circuits from damage due to excess current. When a circuit receives more electrical demand than it can safely handle, the breaker will trip to prevent overheating and potential fire hazards. This repetitive tripping suggests that the circuits are being pushed beyond their capacity, which should be addressed to ensure safety and proper functioning of the electrical system.

Inconsistent lighting may indicate other issues such as faulty wiring or bulb fittings, but it is not a definitive sign of an overload. High energy bills can reflect increased usage but can be influenced by many factors such as appliance efficiency and energy rates, rather than indicating a specific overload condition. Burnt-out light bulbs may suggest problems with the bulbs themselves or the fixtures, but they do not directly signal an electrical system overload. Thus, the option regarding frequent tripping of circuit breakers is the clearest evidence of an overload issue that needs immediate attention.
