Anyone running 3 15M AC's on 50 amp? Follow up added

Would not hurt to measure AC draw.
My 15k Carrier draw 8.2 amp while running, so theoretically I could run 3 of them on 30 amp service, but the motors have huge spike while restarting and that is why they require bigger power line.
Common sense if you want to use 3 of them is to set thermostats on 2 to low and let the 3rd one cycle when it gets too cold.
That will avoid the potential situation when 2 might want to restart in the same time.
