Name a common electrical hazard and a way to mitigate it.

Overloading circuits is a prevalent electrical hazard that occurs when too much electrical load is connected to a single circuit, exceeding its capacity. This can lead to overheating, potential damage to electrical components, and in severe cases, could result in electrical fires. Ensuring that no more than the rated load is connected to any circuit effectively mitigates this risk. The rated load, which is specified by the circuit design, indicates the maximum electrical current that can flow safely without causing overheating.

By adhering to this specification and carefully managing the balance of current in each circuit, electrical workers can prevent the dangerous outcomes associated with overloading. This practice promotes safety in both residential and commercial electrical systems and helps in maintaining the longevity of the electrical infrastructure.

The other options identify valid electrical hazards as well but do not provide the same level of direct relevance to immediate safety concerns associated with circuit overloads. For instance, while using better insulation materials is important, it does not address the urgent risk of completing circuits with loads beyond their capabilities. Similarly, upgrading old equipment and scheduling regular maintenance are good practices but may not directly prevent an overload situation in the moment it occurs.
