What is a major cause of electrical fires?

Overloaded circuits and faulty wiring are significant contributors to electrical fires due to several factors. An overloaded circuit occurs when too many devices are connected to a circuit that cannot handle the total electrical load. This situation generates excessive heat, which can ignite surrounding materials, leading to a fire.

Faulty wiring, on the other hand, may be the result of outdated installations, poor workmanship, wear and tear, or damage. Such wiring can create short circuits, arcing, and the potential for sparks, all of which can easily escalate into a fire hazard if not properly addressed.

Understanding that both overloaded circuits and faulty wiring can compromise the safety of electrical systems is crucial for both contractors and consumers, as careful monitoring and maintenance of electrical installations can significantly reduce the risk of fires.
