I got a new ipad mini and start downloading tons of electrical apps today. One of first things I noticed was how the egc jumps from #12 to #10 from 20 amps to a 60 amp OCPD. Anyone know why the jump like this ? Just curious because it just doesn't seem right for some reason.
EGC size jump 20-60OCPD
