Looking for suggestions or a kit to create a pass through for a door for my generator cord. I purchased a generator this year for my travel trailer and in hind sight i purchased one with a 30 amp rv plug and not the 30 amp twist lock plug. I see all sorts of pass throughs for the twist lock but for me to take advantage of that i would need extra adapters and that gets a little expensive and just creates more room for issues not to mention over the past several years we have not had a power failure. All i would be powering up is my pellet stove and TV so its not going to see a lot of load so i was thinking of just a 15/20 amp extension cord for the pass though.. So far all i have come up with is getting 2 30/50 amp outdoor outlet covers and drilling through the door and having one on both sides and just stuff it with some insulation when not in use.. Then i can just use my heavy duty extension cord and pass it though easily. My doors are to tight to use a lay flat cord under the door so that is not a option.
 
not ripping apart a new generator and voiding my 3 year warranty to change plugs, then i would also have to change my travel trailer where this is primarily used.
 
box on out side with rv plug box on inside with whatever - through wall not door way.

Get an RV to 14-30P adapter cord and use a proper connection box?

I've made two of these. One is for my greenhouse, to pass the hose from a 20# bulk propane tank inside to a BigBuddy radiant heater that is backup heat. The other is on a stick-built shed for my 8.5 kw tri-fuel genertor. The 50 amp ordset plugs into a receptacle hard wired into the main panel box with a manual interrupt switch. In both cases I drilled a hole just large enough to accomodate whatever I was passing through, with a circular piece of scrap aluminium to cover the hole. It 'swings' on a single screw. Both were painted to match the structure. A no-bucks fix....

Not a option i live in a modular with an addition in it that is what i would call air gapped. So between the 2 walls is about a foot and having any wire between the 2 is just asking for trouble since the squirls get in their. I have already had to replace the power going to the addition once with armor cable as they had gotten it and that was no easy task..

Similar to what i was thinking when putting 2 30/50 amp plug covers on the door..
 
use a short piece of emt they can't eat thru that then use thhn wire or uf cable inside of the pipe that goes to the outside plug if you can't find a adapter that is short money you can change the outlet on the box that is outside to the one you need. if you can return the generator to buy a new one that has a twist lock you are better off. a rv plug has no ground. they have three prongs two hot and one neutral no ground. you need a four prong plug to make a 2 hot 1 neutral and 1 ground then run a interlock in your panel and light the whole house. after all what good is a 8.5k watt generator if you have to take a candle in to the toilet 8.5k watt will run the small burner on a electric stove which is 1500 watts or a oven which is 3000 watts maybe 3500 watts
