I'm running it 150' to a 100a panel. If everything's on, the compressor's running and I'm welding (entirely feasible) 1/0 1/0 1/0 0 is borderline. It would be enough if it was 100', but that extra 50' bumps me up one size. But, I'm an amateur. If anybody's a licensed electrician and would like to advise, my ears are open.
A year before Covid I got an electrician shop to give me an estimate on running the wire and wiring up a couple things I had unfinished. They quoted me $5000. I did the other work and then called back right after Covid hit, and the price jumped to $7000, with less work for them to do. For $7000 I'll do it myself. The shop itself is fully conduited with a 100a panel, 12 LED panels in the rafters, a GFI protected 4x box on each 10' section, and 6 NEMA50 220v plugs, and I did that myself.
