Solved Ground Fault Circuit Interrupters Vs Arc Fault Circuit Interrupters
An arc fault circuit interrupter is defined as a device proposed to provide protection from the effects of arc faults by recognizing arcs and by functioning to de energize the circuit when an arc fault is detected.
Solved ground fault circuit interrupters vs arc fault circuit interrupters. The cafci is a new version of the older acfi breaker. Acfis protect against fire causing arcing much like gfci s protect against stray current. Ground fault circuit interrupters help prevent burns electric shocks and electrocution.
