Thanks gfretwell!
My expected load was listed above in original post. Mig at 48-amp will the largest load. I'm not so good with word. My apologies if I things were getting confusing.
I'm well aware of the load expection.. 125% of my largest load has me at 60amp. worst case one person welding one grinding with a 15-Amp grinder. If welder was cranked up with would be 125% 78.75-Amp. However, I don't deal with the real heavy steels. The welder will maybe see full load once or twice in its lifetime at my shop.
I guess I was just looking for confirmation that I was going about this correctly not missing anything in my layout.
