At 12 volts input the 6000 watt inverter could draw more than 500 amps. At 12 volts a wire picked by the NEC heating criteria will have way too much voltage drop, so needs to be as big as you can find and can install. I'd think without computing voltage drop that 4/0 or 350 MCM would be almost adequate for copper.
I don't think the engine alternator will keep up with that inverter load so it can't be continuous. I'd be looking at plumbing in a heater core to the engine cooling system for bus heat.

+1, even if only using the 3500 watt you mention, that at least a continuous 300 amp 12 V load. Would take a very large battery and alternator to keep up with that. Using waste heat from the bus engine is much more practical, with maybe 30 amps 12V to run the heater fans. |
