A fuse wire, or fusable link, is just another form of a fuse and operates much in the same fashion. Too much current draw and poof, it blows. You could replace a fuse wire with a fuse and fuse block but fusable link is much cheaper to manufacture and is good for quick assembly and or limited space.
NO. Usually the positive wire will have the fuse.
The wire may not melt and break if an unsafe current is produced.
The 15 amp fuse.
A circuit breaker does not have a wire fuse in it.
Fuse wire is designed to open under over current conditions. Just like a fuse.
yes there is a fuse in the fuse box. the wire will lead to it or to the ignition switch. But the fuse to amke the hot wire hot is in the under dash mounted fuse box.
Isolate the cicuit in question, or turn off power altogether. Remove the burned/fused section of the fuse wire in the fuse carrier and replace with the recommended fuse wire. Turn power back on.
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
A fused jumper wire is just a wire with or with out alligator clips that has a fuse on it. It can be either buss or blade fuse. You can make one with some parts at autozone or similar parts store.
So that the live wire is isolated when the fuse blows. If a fuse was placed in the neutral, the equipment would still be live when the fuse blows.
The correct size fuse needed is based on the size wire used in the circuit. The size wire needed is based on the load that will be applied to the circuit. 1. AWG 14/2 wire = 15 amp fuse 2. AWG 12/2 wire = 20 amp fuse 3. AWG 10/2 wire = 30 amp fuse 4. AWG 8/2 wire = 40 amp fuse
