We're having our new home wired soon. My husband wants an outlet to run his Mig welder in an entrance room that leads into the basement. The welder (Lincoln Mig 140C) runs on 120 v., 1 phase, 60 Hz. The spec sheet says to run it on a 20 amp circuit. My question is, can we have a 30 amp circuit installed to insure that there is adequate wattage for running the welder with its peak demand? I know we'd have to have 10 ga wire with the 30 amp circuit.
The electrician eluded to a 20 amp circuit being the highest you could put on a 120v system. However, I've seen references to 30 amp circuits, so I'm trying to figure out what all this means.
