there will never be more than one machine on at once, im good but not that good, lighting, prob 20 fluorescents, 1hp motors on the machines one at once, never alot being drawn in one go, tig plant, mig plant, i would be surprised if i ever saw any more than 25 amps in one go, lets put it this way, they were all in my old place and I have a 20amp breaker feeding the garage, and only under full chat with the mig and all lights on did it every now and again trip the switch.
