The sparks that result from cutting or grinding metal can be dangerous. Not only can they burn the eyes and/or skin, but they also can also ignite combustible or flammable materials in the area, causing a fire.

What causes an outlet to arc?

Arc faults are caused by loose, damaged, or corroded wires and terminals. The low-voltage currents can’t be detected by circuit breakers or residual current devices. Over time, they generate enough heat to break down the wiring insulation and ignite any surrounding flammable material.

What causes electricity to spark?

A spark is created when the applied electric field exceeds the dielectric breakdown strength of the intervening medium. … The exponentially-increasing electrons and ions rapidly cause regions of the air in the gap to become electrically conductive in a process called dielectric breakdown.

What does it mean if an outlet sparks?

A sparking electrical outlet may indicate a short circuit, water exposure or aged equipment. Sometimes it’s normal, and sometimes it’s an indicator that there’s something wrong with the outlet.
