fusing dual power wire???

[RangerDangerV2 5,000+ posts]

The saz 3500 calls for a 300 amp external fuse... I have dual power wire going to my saz and I am wondering if I need a 150 amp fuse one each power wire or do I need a 300 amp fuse on each power wire?? Im guessing 150 on each??

I have dual inputs on both my 3000ds and I fused with 150a fuses. They sell a ten pack on amazon for dirt cheap

I could be way off here, but I think that the two imputs on the amp are internally connected to the same power supply. You can test this by running a continuity check on the two imputs with a DMM. Therefor your current would be added together at the node, so assuming both conductors carry equal current that is the proper way of doing it. Someone correct me if I am wrong
