Put in a regular 30a 120v outlet and then serve the 20a circuit from one of these with an S adapter in it

sparkync:
110.3 (b) relates to mfg installation instructions, and technically the panel is 120/240 volt, 3 wire with a grd.

I have seen the 'hot' spliced with two tails to solve the 'two wires in one lug issue.

It is pretty hard to find a legal answer.

John and Greg, if you were inspecting my job, would you turn it down because I jumpered the lugs with 120 volts and labeled it "120 volts" on the outside cover? I want to be right, but I don't want to go overboard with it either. thanks and splicing the "hot" wire seems like a suitable compromise to meet Mfg. installation instructions.

Greg and Big B, the connection for the RV will be on the opposite side of the building than the line feed,(building has a 15ft. ceiling, is 45ft. long, and the RV outlet will be near the back on the opposite side). The whole job will be in 1/2 emt. Not really convenient to use one of the options you have shown, but thanks anyway..

I would probably hold my nose and accept a 2 pole disconnect with a 20 and a 30 in it but I wouldn't like it.
You would certainly need 30a protection on the line side of this feeder (in the house). It would not be a tap.

I would hold my nose also, after speaking with you.

John and Greg, I wasn't trying to be arrogant at all with my question. I hope you didn't take it that way. There will be a 30 amp breaker ahead of the feeder.
The house that the feeder is coming from has already passed rough inspection. I didn't wire it. Most of the time I do work more than is required. That's why I ask these questions to make sure I'm meeting code. The inspectors here may not have even caught the 20 amp recepts. on a 30amp breaker, but because I want to do it right and they trust me, I try my best to do meet the code.

John, I did a job a few weeks ago, that your comment would certainly fit. I worked in a customer's yard where the sewage pump went bad and was overflowing in the yard. Had to work in it late one afternoon for about 3 hours and the next morning for about 4 hrs. I wished holding my nose would have done the trick. smile Thanks for all your comments..

How much load does he really need to serve in the RV when it is docked at home in the first place? My neighbor had a little pigtail that adapted the RV plug to a 5-15 and that was enough to run a lot of stuff.

Greg, He told me that he would never be using more than one outlet at a time. I think he is retired. He is going to have a work bench at the back of the building, but the recpts. are just for convenience, no constant load. Only real load will be for his RV. I don't have one, so I really don't know what will be working while plugged up. I guess to keep the refrig. etc. going while it is setting there? Think if it comes down to it, and the AHJ has a problem with it, I could put it all on a 20 amp, and see if that's enough to keep the RV going, unless he's going to be living in it or working in it while it's setting and needs the A/C and cooking equipment?

I doubt the AC will run on the single pole 30 anyway. You usually need the 240/50a connected for that.
Cooking is generally propane except for a microwave. You are left with a mini fridge, lights and the TV on most small RVs.
There are land yachts that barely get by on the 240/50.

I think this one has 2.
