Often overlooked inciscussion of electical service and unclear to some not familiar with electicity is that 20 amp, 30 amp, etcetera, when talking about service are rating of the maximum available, If I am plugged into a 30A, I may be using on 5 or 6 amps, based on what is turn on. In those cases a 20 amp service would work. If I turn on the water heater, toaster, etc., I may be using 25- 26 amps, in which vase the 20 amp breaker would trip but the 30A would be OK.
50A servicee has an extra wrinkle but if you buy the correct commercially made adapter you will be OK. But even though though the pedestal may make 50A available, you TC will limit itself to its 30A rating.
