Arc Flash Information Argo Electrical Services
An arcing fault is the flow of current through the air between phase conductors or phase conductors and neutral or ground. An arcing fault can release tremendous amounts of concentrated radiant energy at the point of the arcing in a small fraction of a second resulting in extremely high temperatures, a tremendous pressure blast, and shrapnel ...
What Is an Arc Fault and What Causes It? - The Spruce
An arc fault, as mentioned above, is when loose wire connections or corroded wires cause sparking or arcing, which may create heat and the potential for electrical fires. It may be a precursor to a short circuit or ground-fault, but in and of itself, an arc fault may not shut down either a GFCI or a circuit breaker.
Arc Fault Protection - What its all About
Arcing faults can occur in one of two ways, series arcing faults or parallel arcing faults, but the most dangerous of these is the parallel arc. A series arc can occur when the conductor in series with the load is unintentionally broken.
