Fuses are available various
sizes and types. For this reason, some circuits are equipped with a
ground fault circuit interrupter (GFCI). GFCI
circuit breaker combines protection for ground faults, overloads,
and short circuits one device.

Fuse Class letter designation given fuse identify its operating and
construction characteristics. Renewable fuses allow the user replace the link
and non-renewable fuses not.
