and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.

What happens when a cable overheats?

Once a wire gets hot,

the heat can travel along the wire until it gets to an electrical connection

cooling system failure
