I used #2 welding cable and soldered copper lugs on each end. I ran the wire from the batteries (under driver's door... FL Classic), drilled a hole in the corner of the floor in the driver's side jockey box and another hole in the front of the bunk. I mounted the inverter on the front of the bunk in the sleeper area, about 10" from the driver's side, outside wall (the plugs were then just behind the front face of the fridge I mounted). Instead of a battery switch I used a couple of welding cable quick-connects to disconnect the inverter from the battery when parked for long periods. As well as a colour coding stripe made with electrical tape on the positive cable, I reversed each set of quick connects so the positive and negative cables couldn't be accidentally reversed and oriented them so the negative cable from the battery had the male quick connect end.
All drilled holes were grommeted the cables were wire-tied together and to mounting points on the truck and run inside of plastic cable cover.

That's how they are supposed to be installed. I have a Tripp lite 3000w(6000peak) and it has allocationsfor two sets of cables with each on a 250a cicuit breaker. In the past, I ran an APU but nhave a new truck coming and am going to install a between the rails battery box with 4 Odyssey AGM deep cycle, the inverter, a 12V A/C and Esparsfor heat and engine heat. I will ustilze a Sterling digital Alt to Battery dual bank charger. If this causes tom rapid a drain on my battery bank I will also get the new Kohler, single cylinder air cooled diesel landini 12V only charger that weighs 220 and mounts onm the rail. I think thats as green as you can get. I am hoping I can void the Kohler altogether. I will only use the invertor for cooking with a convection oven and\or an electric fry pan for 1-2 hours a day.Elroythekid and BigJohn54 Thank this. -
Yup... 1 or 2 gauge stranded copper wire is about where you want to be. In power systems, the small amount of resistance in the cable can play havoc with the input circuitry of the inverter, so keeping to heavy cables is a good idea - not to mention what can happen if you overheat the insulation by using skinny wire. The heavier the cable, the better off you are. You're also well advised to fuse this circuit near the battery connection.
If you can't find a good entry point in the sleeper, you may have to drill a hole... you'll want to find some plastic or nylon material to insulate that hole - plus use some wire loom around the cables.BigJohn54 Thanks this. -
I just looked, all 4 of mine are all 2 gauge. I actually had to clip a few strands off each to fit it into the lugs on the invertor.
overkill.... absolutely, but I had it all laying around the shop so why notBigJohn54 Thanks this. -
BigJohn54 Thanks this.

I see a couple ppl mentioned blackrock...i was just talking with a driver that had a gogreen apu and he said it was great. http://www.gogreenapu.com/ i was lookimg at website today and it says they took over blackrock apu.

Bought 3000 watt Powerdrive on sale!
But they did not include fuse holder/fuse!
Where do I get it and what size do I buy?
Install at battery positive to wire?
