Will Using a 50 Amp to 30 Amp Adapter Still Allow Me To Plug My Trailer Into a Generator


I have a 50 amp/220v system in my 5th wheel. With an adapter I can go from a 50a/220v to 30a/110. How do I know that purchasing a 2k generator will power the correct side of the bus to operate my recently installed non-ducted Atwood AC unit? I have not seen this type of question before and it seems that it must have been asked since plugging in this adapter would of necessity power only one half of the buss and only operate just some appliances. Yes? Thanks for your help.

It sounds like you are trying to adapt the 50 amp service on your RV down to a 30 amp service with an adapter like the Mighty Cord Generator Adapter part # A10-G30450VP that way you can plug-in and run your air conditioner unit with a portable generator like the etrailer 2,000-Watt Portable Inverter Generator part # 333-0001. If that is the case then you do not need to worry about pin configuration as the generator, power adapter, and RV will all use an industry standard layout. The hot, neutral, and ground pins for the 30 amp service will be in the same location on the male end of the adapter and the female end of the generator. The 50 amp to 30 amp service adapter will also position the pins correctly so that you won't have any issues when using the power cord on your generator. As previously stated, it is all a standard layout for RV's.

Please note that the above etrailer 2,000-Watt Portable Inverter Generator would not be nearly powerful enough to start the Atwood Air Command Rooftop RV Air Conditioner part # AT15025-21 that you referenced. The main issue you run into with rooftop air conditioners is starting watts. The Atwood Air Command Rooftop RV Air Conditioner will require 3,795 watts upon startup therefore you will need to use a higher rated generator like the etrailer 4,900-Watt Portable Inverter Generators part # 333-0001-0002 which are rated for 4,900 watts starting and 4,2750 watts running.
