[QUOTE="Proximity, post: 5773710, member: 589997"] I was reading through the fuses page and when it's talking about fusing with a distribution block it doesn't really seem like it makes sense and I'm looking for what others think. [URL="http://bcae1.com/fuses.htm"]http://bcae1.com/fuses.htm[/URL] Basically it says when you're reducing a wire size from a distro. block that it needs to be refused. This is the diagram the used for the example: [IMG]http://i41.tinypic.com/2425zeb.jpg[/IMG] It says wire C would not need to be fused because it's the same size as wire B (which the 125a fuse protects) but the 125a fuse would not protect wire D in the event of a short. It seems to me like if there is a short, pretty much any reasonable fuse size would protect it as going by ohm's law if the positive wire come in contact with the frame it would pull thousands of amps, which any fuse would protect. So the only fuse you would need is the 125a fuse as it would protect every single wire on the distribution block. Am I wrong? [/QUOTE]
