What is a common symptom of electrical overload?

Overheating of equipment is a common symptom of electrical overload because it indicates that an excessive amount of electrical current is flowing through the wirings and devices. This can occur when too many appliances are connected to a single circuit or if the circuit is not rated to handle the load being drawn. The increased flow of current causes the wires and components to heat up past their normal operating temperatures, which can lead to insulation failure, potential fire hazards, and damage to the electrical systems and devices.

Understanding this concept is crucial for linemen and electricians, as recognizing the signs of overload allows them to take preventive measures to ensure safety and maintain the integrity of the electrical systems they work with. In contrast, while symptoms like brightening lights, frequent power outages, and buzzing noises from outlets might occur due to various electrical issues, they are less definitive indicators of an overload situation.
