Multiple strands of wire…
October 12, 2009
Just a little blurb.
Say, for example, you need 4gauge wire. But you can get the same gauge equivalent by running multiple runs of 16 gauge wire, and it’s cheaper.
The first reason this is a bad idea (and more expensive, even) is that EACH wire has to be fused. You can’t have one big fuse for all the wires; if one wire short-circuits, a single large fuse won’t catch it (obviously, as current draw for that particular wire isn’t enough to blow it). This could get really bulky and really expensive.
In short, it isn’t worth it: just get the right size gauge of wire.
