What is an arc fault?

There are two kinds of arcing faults. Both have the potential to ignite a fire.

A parallel arc, also known as a high-current arc, is an arc that jumps between the hot and neutral wires, or the hot and ground wires.
Conditions for a parallel arc can be created when a nail is driven through a cable, a staple is installed too tightly around a cable, or the cable insulation is damaged by something sharp like a truss gusset.

A series arc, also known as a low-current arc, occurs across a gap on a single conductor.
Conditions for a series arc can be created if a conductor is crushed, a connection is loose, or the conductor is pulled apart.
