What Is the Correct Fuse to Use When Fusing a Battery Bank Before the Distribution Panel?


I want to fuse my new house battery bank before the distribution panel, what is the formula for the right fuse to use, I have two batteries on number two wire. - Jeff


Thanks for contacting PYS about electrical systems. Sizing the fuse really depends on what sort of loads you have from the house panel. The maximum fuse you should use is based on this chart, https://www.solaris-shop.com/content/American%20Wire%20Gauge%20Conductor%20Size%20Table.pdf   I would suggest going with an 80 amp fuse to protect the wire. - Jeff
