Hi All,
Correction: Another Wrench member contacted me off-list and noticed that we have a class RK5 in one photo and a T in the other photo. This opens up the question of whether one or both are correct or incorrect. I think both are rated for 20k AIC for DC voltage but I'll have to look through my order records to be certain. The R is slow acting and the T is fast acting.

We've been fusing with a class T in the battery box and grounding the negative side of the batteries. See attached pics. Do you feel that the fuses should be outside of the battery box?

It's really time consuming and ugly to run big parallel battery string wires *out* of the battery enclosure to class T fuses, then back into the battery box. It looks very ugly and DIY, and in conduit adds a few hundred to the install cost just for labor. The Class T fuses and blocks themselves are not particularly expensive. I have been recommending parallel fusing on battery banks of 2x8 L16s and over now, after a nearly tragic incident with a bad cell that shorted. The (perfectly legal) wooden battery box made the fire much worse. A pet peeve of mine.
