[QUOTE="brynm, post: 7715162, member: 566714"] Yes there is more danger with the 200 amp fuse. If there was a partial short, I keep saying partial because a dead short might pop even the bigger fuse fast enough, there could be say 190A of current going through a wire that is rated for a max of 125A. The fuse won't blow and you may not find out until the insulation melts off the wire and you have a fire. It's ok to fuse under the max rating of a wire, not over it. These are examples of what could happen, first vid wire rated for 15A loaded with a welder on a 50A breaker. Second vid is an extreme example I'll admit. [MEDIA=youtube]jK8FfAZmCPw[/MEDIA] [/QUOTE]
