Class T is better in a DC system and more is better in a circuit when it comes to fuse protection. DC current can arc across and open ANL element that has burned in half due to a short. Even open, if you have enough current it can jump across with DC. Take a look at an arc welder for proof. The class T has elements inside that are surrounded by material (silica sand, I believe) that absorbs that arcing. And some class T fuses I've seen are rated up to 200,000 amps, against arcing current. For personal protection and property protection class T is much better.I'm about to start my upgrade to our RV electrical system. It will be a Victron MultiPlus 3000 with 4 Battleborn Batteries and 700 watts of solar. I went and go everything from BattleBorn but noticed that they supplied me with a 400 Amp ANL fuse to place between the battery and the inverter (it would have been nice if they supplied the fuse holder as well). Prior research that I've done indicates that a 400 Amp Class T fuse would be a better choice. But since I'm sure that the people at BattleBorn know more than I do should I just go with the ANL type, or replace it with a Class T? The cost difference doesn't matter to me. My primary concern is keeping my RV electrical system and everyone in the RV as safe as possible at all times.. Thoughts?
