[QUOTE="SoundsGood, post: 746897, member: 552735"] I recently added a dist block for a second amp and the info I always got was to fuse for the wire that you are using. The fuse is there to blow if too much power runs through the wire. If there is no fuse and there is a problem the wire will heat and cause fire. The 1/0 wire (I used the same thing) can handle 350 amps. Here is a good chart to give you some ideas [URL="http://www.the12volt.com/info/recwirsz.asp"]http://www.the12volt.com/info/recwirsz.asp[/URL] I've seen some debate about circuit breakers vs. fuses. [URL="http://www.bace1.com"]http://www.bace1.com[/URL] is very informative if you've got some extra time. Personally I went with a fuse. You also need to fuse either in the dist. block or soon after because the four gauge wire has a different load compacity (150) amps. The amp will have its own fuse to protect it so you don't have to 'add up' fuses for multiple amps. I thought the same way as you did. I've also found that the best tool (when I have a question...and thats alot) is to use the 'search forum'. Most often somebody has had the same problem or same question that you've got. Hope this gave you a little insight with fuses and what they actually do. [/QUOTE]
