[QUOTE="n2audio, post: 8538701, member: 540940"] There is no electrical advantage to running a single wire to a distribution block. It is mainly about neatness and personal preference. Huh? [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] There are unfused d-blocks everywhere. And you'd be fine if you did that -- possibly better off. Just check the wire specs instead of trusting some random thing some random dude on CA said to do. That's not universally true. Just look around. It's a bad example. x999 Fusing after the firewall is almost pointless. 18" is often quoted as a "standard". There is no standard. The standard SHOULD be -- "as close as reasonably possible." 18" is ok in most cases, but if you can make it 12" do that. The point is just that you want as little wire unprotected as possible, and nothing rubbing against the wire over that length. Shouldn't do that if the wire changes size. If you have 1/0 fust at 250A to a solid d-block and 8 to the amp you have a 250A fuse protecting an 8 awg wire. It won't protect it. If the 8 awg gets shorted it could melt and burn before the big fuse blows. [/QUOTE]
