Circuit Protection Devices Examples. Circuit protection devices protect expensive systems by rapidly disconnecting power to compon ents in the event of an ab normal operating condition. A manufacturer would use a smaller inline fuse or 20 gauge wire to protect a circuit that consists of 16 gauge wire.
A manufacturer would use a smaller inline fuse or 20 gauge wire to protect a circuit that consists of 16 gauge wire. It blows and breaks the circuit should the current exceed the rating of the fuse. A 20 gauge wire is smaller and burns to create an open before the 16 gauge wire does.
One classic example of self protection is short circuit protection with the use of a fuse.
Even though guidance exists in the form of the various electrical codes the wide variety of product offerings can make the proper selection of circuit protection devices a challenge.

An inline fuse is a wire that s 4 sizes smaller than the circuit itself. A fuse is a very basic protection device which is destroyed i e.
