For this reason, some circuits are equipped with a
ground fault circuit interrupter (GFCI). Ground faults can endanger people and damage
equipment.This usually accomplished when metal link the
fuse melts.
German Institute for Recognized since 1975 the standards organization that
Standardization (DIN) represents German interests nationally and internationally. GFCI installed near the receptacles it
protects, overcurrent protection required separately.
