I understand that the 50A service actually provides 2 legs of 120V (L0-L1 & L0-L2) @ 30A and this is why I asked if using the 50A pedestal outlet would be a better option than plugging into the 20A outlet.
The 50A service is 50A on each leg at 120V or 50A at 240V or a combination of both 120V and 240V not to exceed 50A on either leg. Very few RVs have 240 appliances.
I have not been able to find a 20A EMS unit.
The 30A EMS will work. They ignore amps except for the display.
BTW - I don't understand why manufacturers are still building larger RVs with 30A service. The additional cost must be less than $1000, and anyone who wants to install a second A/C unit is forced to jerry-rig something that should have been a straight forward modification.
The buyers don't want to pay for something they are clueless about.
