What is a combination AFCI?

A combination AFCI is a device that detects both, series and parallel arc faults.

A series arc fault occurs when the conductor in series with the load breaks and arcing occurs between the ends of the conductor or when a conductor termination becomes loose.

A parallel arc fault occurs as a ground fault where an energized phase conductor contacts an opposing phase conductor or a short circuit occurs between a phase conductor and a grounded surface.
