Ground faults can endanger people and damage
equipment.
Ground Fault Circuit device designed interrupt current circuit ground
Interrupter (GFCI) fault sensed. Some have time delay.
German Institute for Recognized since 1975 the standards organization that
Standardization (DIN) represents German interests nationally and internationally.
Ground connection the earth conductive object such an
equipment chassis.
Fuse Class letter designation given fuse identify its operating and
construction characteristics. GFCI
circuit breaker combines protection for ground faults, overloads,
and short circuits one device.15
Fuse device designed open circuit when its rated current is
exceeded. Renewable fuses allow the user replace the link
and non-renewable fuses not.This usually accomplished when metal link the
fuse melts. For this reason, some circuits are equipped with a
ground fault circuit interrupter (GFCI).
