An arc fault occurs when electrical wiring connections create unwanted contact with each other. This leads to sparks and hissing sounds, along with increasing heat that can wear through the insulation that protects your wires. Keep reading for a look at what causes these faults, as well as the dangers they can represent. 

How Do Arc Faults Occur?

When an electrical wiring connection gets damaged, there is the risk of an arc forming. Hot spots in the cables affect the insulation around them, “carbonizing” it. Carbon is conductive; this means the current will be able to flow right through the insulating layer. 

The arcs lead to more carbonization as they progress, creating a chain reaction that could end up producing sparks. Arc faults can also form if the insulation between two live conductors is damaged, or if there are bad connections on switches or power strips. 

Why Are Arc Faults Dangerous? 

Much of their danger comes from the fact that arc faults can go unnoticed for a long time. While they develop, insulation around your wires will deteriorate, and the arc chain reaction could wind up starting an electrical fire. Unless you were able to identify the buzzing and hissing sounds of an arc in progress, this fire would be unexpected and more likely to catch you by surprise. 

Arc faults can also lead to power outages, damaged outlets and appliances, and electric shock. Attempting to repair one, unless you’re a professional, can be very dangerous, in addition to carrying the risk of only making the problem worse.
