You will find this a very interesting 'book':
Victron Wiring Unlimited

Yeah man. I got it. Read it. Doesn't really answer the questions I have or at least I don't see it. I was hoping to get a series of simple answers for myself and everyone else as there seems to be a ton of people out there asking the same thing

1. .The grounding section of wiring unlimited doesn't have an example while using a shunt. That was one of my questions... is the grounding wire for the negative side of my system on the system side bus bar or battery side bus bar of the shunt or does it matter? Another question was that the manual says to size the chassis ground wires for each component according to the fuse size or basically the same size i fed the xomponent with, which doesnt make sense to me. I own an havc company and have compressors run at 20 amps on a 30 amp circuit but have a locked rotor of 90 amps but only a 14 guage ground wire. They short out and sometimes to ground and actually blow the whole house main 200 amp breaker but the 14 guage ground wire nor the 20 guage feed wire aren't hurt. I know that's ac voltage, so it is a different animal but still no explanation. With the dc voltage wouldn't a dead short cause a near instantaneous trip of the breaker amperage wise and the wire only sees the load for milliseconds. And wouldn't a minor short instantly blow the ground fault. And if I do have to run these massive ground wires then how big does my actual final ground wire going to my external earth ground rod have to be? Sorry I unloaded there. Maybe these answers are in the books somewhere but I didn't see them and certainly not coniguosly. By the way local code/inspection compliance is not an issue on this.
