I want to hard wire a air compressor in my truck, and it can draw up to 90amps especially on startup.
As the bcdc1220 is current limited to 20 amps the 30 amp fuse is sufficient for any wire size. Battery cable and related bulk wire items made in the usa from high purity copper and sold by the foot, custom cut to order. Yes keep the cables all the same gage.
2/0 or 3/0 for the starter 2/0 for battery grounds i have left my glow plug alone for now but i would just go up one size from whatever it is if you wanted to alternator wiring must be left as it is, but you can add a wire to it and go from the alt to the drivers side battery. Electrical wire sizes & gauges: Wire size between batteries wire gauge for a battery bank really depends a lot on your expected loads (and charging current).
When selecting the correct size of a battery cable to power your electrical system or project, a few factors need to be considered.you should know what is the maximum amount of current your system will need, how long the cables need to be, and the cost of larger cables versus smaller cables.
