Getting ready to install my 12/2000 Multiplus on my 272AH 12V battery bank, Daly 250A 4S BMS. Anyway I read on the forums here to use 4/0 wire. While that sounds great and all my Negative wire is limited to the small wire of my BMS. I also read to use a 350/400A Fuse/Breaker on my Positive side, while that is fine, Should I limit that to a 250A so I don't exceed 1C of my BMS?
What size fuse/breaker should I use?
Do I need to run 4/0 or will something smaller like 1/0 be sufficient? (<5' Run.)
