It explains why all my GM vehicles end up needing their ground wires replaced with heavier ones.eggsalad wrote:http://www.gmupfitter.com/publicat/elec ... df#page=22

If the wires are small enough and not fused they act like resistance heating element wires.
Depending on what yer trying to accomplish the above can come in handy.

You can even do some playing around like I did for one project and push 200 Amps through a 22 AWG wire. Just don't try to do it for extended periods like for more than a tenth of a second.![]()
It takes some time for the heat to build up enough that it acts like a fuse. Actually, that's all fuses are. A small piece of wire meant to burn up if to many amps try to pass through it. Usually they contain the wire in something, like a glass sleeve, that will keep the molten metal from damaging other things.
