I just purchased and received in the mail today, a EV-CUT40D Plasma cutter. The instructions are a little ambiguous however.

What are the current requirements if I hook this up to 110VAC or 220VAC.

In other words, if I hook this up to 110 VAC Single Phase, how big of a circuit breaker do I need for the outlet circuit?

I also have 220 VAC available, but again I don't know how big of a circuit breaker is required for the outlet. Would a double pole 20 amp breaker be sufficient or do I need a larger one.

Also there is a blue, a brown and a green wire going into the cutter.

If I hook up to 110 VAC, I assume the green is for earth ground but which wire, blue or brown is the hot wire and which is the electrical ground.

If I hook it up to 220 VAC, can I assume correctly that the blue and the brown are both 110VAC legs and the green is the electrical ground?

Please advise as I would like to get this up and running,

Thanks in advance for any and all assistance you can give me.
