[QUOTE="condor22, post: 397133, member: 1932"] It was wired for me on my last ride. 6mm sq was used. The highlight here is that if I was running a compressor fridge, Engel in car and Vitrifigo van fridge pulling 3-4 amps, 6 mm was ok. But when I changed vans it was a 3 way pulling 14 amps. So wire gauge is not only relevant to the distance between battery and load/charge, current also plays a part. When wiring a 1-2 kVA inverter bear in mind an inverter pulls about 9 amps per 100W @ 12VDC. So for a microwave sized inverter the load is likely around 110-135 amps depending on microwave. Your talking wire the size of that used on a car battery or bigger and for very short distances. A good example to think about is that a winch will use anywhere between 350 to 500 amps, look at the cable size used and the short distances run ... :) So a short run of heavy 12 volt between battery and inverter, you can always use longer 240VAC wiring between the inverter and microwave where it's not as critical.
