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 live wire
Every fuse is rated for some certain current. The rating is the maximum currentthat can flow through the fuse before the wire in it gets so hot that it melts andopens the circuit. (In the arcane jargon of the high-tech world of engineering,especially electrical, this event is described by saying that the fuse "blew".)The thinner the wire is, the less current it can conduct before the wire melts.The thicker the wire is, the more current it can carry before the wire melts.So, the wire you select for your fuse completely depends on the current forwhich you want to rate your fuse, and above which you want it to "blow".

Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
Normally aluminum, zinc, copper, or an alloy that will provide predictable characteristics and blow under the conditions the fuse was designed for.
NO. Usually the positive wire will have the fuse.
Why is it dangerous to replace a fuse with a wire that bypasses the fuse
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
