Name a method to prevent overheating of wires.

Using properly sized wire gauges for the electrical load is essential in preventing overheating of wires. Each wire gauge is rated for a specific current-carrying capacity, known as ampacity. When the wire is too small for the amount of current it needs to carry, it can lead to excessive heat generation due to resistance. This overheating can result in potential hazards such as wire insulation failure, which can lead to shorts, equipment damage, or even fires.

By selecting a wire gauge that matches or exceeds the requirements of the electrical load, electricians ensure that the wire can safely handle the electrical current without suffering from excessive heat buildup. This practice is fundamental in electrical safety and is a key consideration during design and installation to create efficient and safe electrical systems.
