[QUOTE="wew lad, post: 8390482, member: 665412"] Okay say you're right, I always appreciate an intelligent discussion. Here's where I find a problem with it, you mentioned that a fuse may have 1% more resistance than another, maybe that's not a lot or enough to make a difference but if you think about it and how electricity flows you should know that it's not a direct relationship. A 1% increase in resistance does change the way electricity flows. Remember that it follows the EASIEST path to follow, our fuse with less resistance. This means that electricity will first follow our fuse with less resistance, and yes it will carry more current at any time than our other fuse with more resistance. This means (in theory) that our less resistible fuse will carry the majority of the capacity until its resistance increases enough to cause the current to flow into the second fuse (if the first fuse heats up, saturates, or most likely, blows). Then you have one fuse blown and a second fuse that's half the rating of what you need and it blows immediately. You can't dispute that the resistance is going to cause one fuse to carry more current than the other, but you can dispute whether or not that would cause a premature failure of one fusee before another. That is what I want to know, and although your analogy makes sense there are a lot of different variables when it comes to running fuses in parallel on a circuit board and I am not an electrical engineer.
