[AT] Wire size for welder?? Help welder people!

[Dudley Rupert]

John,

I hope the following little table showing Load, Circuit Breaker and Wire
Size transmits in a readable fashion -

I took it from the NEC (National Electrical Code) probably 25 years ago but
I can't imagine it has changed.

      Load     Circuit Breaker        Wire Size
=<15 amps      15 amp         Not less than #14
=<20 amps      20 amp         Not less than #12
=<30 amps      30 amp         Not less than #10

If I have a 230 volt mig welder that is rated at 45 amps input current I
assume I would want a 50 amp 230 volt breaker .  But what minimum romex
wire gauge would I need to run 25' from the breaker box to the outlet box
for the welder?   For years I've used 10 gauge wire for my 225 amp output
Lincoln buzz box.     John W.

                    In the wide-open spaces of NE Oregon
