If a wire is getting too hot, what might this indicate according to the technicians?

A wire getting too hot is often an indication of higher-than-normal current running through it. When current flows through a conductor, it generates heat due to the resistance present in the wire. If the current exceeds the wire's rated capacity, the excessive heat can lead to insulation damage or even cause a fire hazard. This scenario emphasizes the importance of using the correct wire gauge for a specific application to prevent overheating.

While broken individual strands or faulty connectors can also cause issues, they typically result in electrical resistance at a specific point, which may not uniformly raise the temperature of the entire wire. Inadequate wire gauge can contribute to overheating, but the primary direct cause of an increase in temperature is the current itself. A wire’s heat generation is a direct function of the amount of current flowing through it, reinforcing the idea that monitoring current levels is crucial for safe and effective electrical system maintenance.
