So can a 50 amp outlet be 110 volt or are they, or can they be 220 volt? How do you tell?

They are 220, across the 2 hots, the 50-30 adapter only uses 1 hot so no issue

Other than the fact the voltage is actually 240 volts AC, this is the correct answer. There is no such thing in residential wiring where a single wire carries 240 volts. All 240 volt outlets are as described, two separate 120 volt lines, out of phase that measure 240 volts AC between them. Measuring between either hot line to either the ground or the neutral the voltage will result in 120 volts AC. Harbor Freight sells volt meters for less than $10.00. They are extremely easy to use. Using one is the best tool and easiest way to confirm a questionable outlet is properly wired.
