Which size wire I need to run 220 volt breaker for a tanning bed
Choosing the appropriate wire size is of course about amperage, not voltage. Tester101 is completely right about the 4/0 conductors handling 220 amps, and also about needing to check the nameplate on the tanning bed where it should list the electrical requirements (or look up the model in the service manual or on the web).
What wire gauge should I use with a 30 amp breaker for a 220V …
The receptacles do have to be marked For Welder Use Only. So, I guess you could use 10 ga wire with a 60 amp breaker if it was only used for a welder with 50% or less duty cycle. That said, I use 6 ga wire with a 50 amp breaker and either a NEMA 6-50 or 14-50 receptacle for all of my single phase small to medium size welders and plasma cutters.
