I'm trying to decide what amp fuse to install on a battery block: i.e. the Blue Seas Block Terminal. I contacted Blue Seas, stating that i have 2 group 29 batteries with a reserve of 170 amps; plus a starting battery. They replied it's not a matter of battery amps, but what size wire I'm trying to protect. Ok. How about 1/0; I got no reply. It seems I would need something less than a 170 amp fuse for the house bank. Is there a rule of thumb estimate? O Simply add up the value of the breakers on the electrical panel? Then there's the question of cranking amps. If the starting battery has 600 cranking amps, hows does that enter the equation? And the glow plugs? I'd like to hear your thots and experience with this.
