Can Old Wiring Cause Fires?

That’s not good because old, outdated wiring could pose a fire hazard. As electrical components age or become overloaded, the system can overheat and wear out insulation. This can lead to arcs (electrical discharge) and short circuits — the two main causes of home electrical wiring fires, according to the CPSC.

Can electrical wiring catch fire?

Wiring with deteriorating coating or wires can easily arc and start a fire, especially if the wire does not match the circuit amperage. The higher the amperage rating of the circuit, the larger the wires need to be in order to avoid excess heat that can melt wires and cause fires.
