Battery Fuses

I am a strong believer in over current protection or fusing of battery banks, even start banks on smaller axillary engines, despite this not being a requirement to meet in ABYC E-11.


This product is called a battery terminal fuse.. These fuses are meant to protect the wiring from dead shorts and are easy to install. I use the double version for the bank and the alternator wire. As always choose your fuses based on the wire gauge you are protecting.


Every positive wire connected to a batter should be fused within 7" of the battery or as close as you can get. This includes inverters, alternators, battery chargers, bilge pumps or stereo memory wires.


Interestingly enough the black fuse holder for this Victron battery monitor is 7" from the ring terminal for the battery post.
