What Causes Electrical Wires To Melt

By | August 15, 2022



We’ve all experienced a time when the power goes out and suddenly we’re without the lights, the air conditioning, or the gas stove. In some cases, the cause of the outage may be traced back to melted electrical wires. While this can be a frightening occurrence, it’s important to understand the causes of electrical wires melting in order to prevent a similar incident in the future.

There are several issues that can cause electrical wires to melt. Firstly, if the wiring is rated incorrectly for the amount of current it will receive, the insulation on the wire can become extremely hot and eventually melt. The same thing can happen if the wires have been damaged from animal activity or some other external influences, allowing too much heat to build up along the length of the wire. Other causes include poor connections, loose fixtures, or overloaded circuits.

What’s more, improperly placed outlets can create fire hazards by allowing arcing electricity to occur on the exposed metal components of the outlet. This phenomenon, called “arc-faulting”, can cause electrical wires to spark or even melt over time if left unchecked. The best way to prevent melted electrical wires is to invest in quality materials, professional installation, and regular inspections and maintenance. By eliminating these potentially dangerous issues, you can help ensure your home remains powered and safe.
