Can you run a 220v A/C unit off a 50 amp service?
Can you run a 220v A/C unit off a 50 amp service? I want to install a mini split unit and Im totally confused about "two hot feeds- split main breaker box" Thanks for responses.

The short answer is yes. PROVIDED you are on 50 amps and not 30 it won't work at all on 30.
The longer answer however is a tad more complex.
Now normally 50 amp service is L1-N-L2 back at the transformer there is one winding. L-1 and L-2 are the ends of the winding. N is a center tap. So it's 120-120 or 240 volt overall.
And your A/C will work
Some parks however .. "Cheat.. They feed 100 amps down the wire, and use it to feed both legs of the 50 amp outlet.. An Intelletec EMS will detect this as 30 amp service (For that is how the voltages are "Split" when you use a 30 amp dogbone)
Since there is zero leg to leg voltage. the 240 volt unit will not work in such a park or on a 30 amp site..
Thus I would NOT recommend such a unit.
