The top numbers for power draw that I marked in red use as much as 3300 watts so 20 amp is needed to be safe.
Note that is pro model in a hot room on turbo 3371 watts.
Lastly 200 to 240 volts. Means my garage is out as it can drift up to 245 volts.
My spot in Clifton NJ is better 226 to 229 watts.
What happens if voltage goes above 240?
Mine ranges from 117-123 on the 120 volt side. It was about 118 when I measured 237 on the 240 volt circuit.
