dsmdan Posted October 25, 2009 Report Share Posted October 25, 2009 Hi, I am running 2 strands of 1/0 wire from the front to rear in my truck. The amp's fuse rating is 300a. Should I install 150a fuses in each of the runs of 1/0, or 300a fuses in both? Also, I am installing a DC Power 270xp alternator in my truck, along with the big 3, etc. Is is mandatory to run an inline fuse off the alt to the battery? And if so, what fuse rating should I go with, I was thinking 300a. Thank you.

brewer_brewer Posted October 25, 2009 Report Share Posted October 25, 2009 i would run 200a or higher for both wires the 150a fuses could limit the amp a little. remember fuses are current limiters. what amp btw?

And I already have enough 300a fuses, but I'd need to order some lesser amp ones. Will it be safe running both 300a?

brewer_brewer Posted October 25, 2009 Report Share Posted October 25, 2009 (edited) yea i would stick with the 300a per 0 gauge and no fuse from alt to batt. as always make sure you have strong connections. what kind of 0gauge do you have? EDIT:meant stick wit 300 not 200 since you already have them Edited October 25, 2009 by brewer_brewer Quote REFS http://www.caraudioclassifieds.org/forum/itrader.php?u=2026 http://www.stevemeadedesigns.com/board/topic/44535-official-brewer-brewer-feedback/page__p__625998__hl__brewer__fromsearch__1entry625998 "you're not allowing natural selection to work, you're like the guy that invented the seatbelt" Link to comment Share on other sites More sharing options...
AI James Posted October 25, 2009 Report Share Posted October 25, 2009 (edited) you are supposed to fuse for the wire not the amp, the 300 amp fuse is for the rating of wire not the amp. ie if you run 10 runs of 1/0 you need 10 300 amp fuses Edited October 25, 2009 by Accordman Quote Link to comment Share on other sites More sharing options...
