Reason being, I can get a lot of it for real cheap. canolprene welding cable---600v---arg 259. Is this cable 2/0 with more insulation? arg 259 is fat. and looks as though maybe more strand of copper than 2/0. But I haven't had any of that laying around in a while to compare. I am building a hopper. And can't help but gas hop from time to time. So the inside disconnect is a must. I've thought hard about split bank with one in the trunk as well. Does anybody know if this cable is too fat to fit in our style disconnects, or maybe bad experience with ground issues? I know there has been much debate about running wire that far for ground. But I have used 2/0 to the front no problems before.
