STOP! DO NOT DO THIS!
Why exactly would you want to do this?
Are you aware of the dangers of plugging an appliance which draws 30 Amps into a circuit which is protected by 50 Amp breakers?
If something went wrong with the 30 Amp appliance running on a 50A circuit it could catch fire or kill someone because the 50 Amp breakers did not cut the power.

By asking this question you are probably not quite ready to take on this particular task.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

To change a motorhome from 30 amp to 50 amp service, you would need to upgrade the electrical system. This usually involves installing a new 50 amp shore power inlet, upgrading the wiring, and installing a new 50 amp breaker panel. It's important to have a professional electrician or RV technician perform this upgrade to ensure it is done safely and correctly.
Probably nothing. And if your RV service panel is protected with a 30 amp main breaker, you are good to go.
But if you do not have 30 amp protection on a 30 amp plug, and you begin to draw above 30 amps, you run the risk of meltdown. If this occurs and you are drawing less than 50 amps, you get a fire.
Not good.
Yes, there are adapters available that allow you to connect a NEMA 14-30 plug to a NEMA 14-50 receptacle. These adapters typically have a NEMA 14-30 female connector on one end and a NEMA 14-50 male connector on the other end, allowing compatibility between the two different outlet types.
30
No, you should not plug a 30 amp air conditioner into a 50 amp plug. The appliance should be plugged into a compatible outlet to prevent electrical issues or damage to the unit. It's best to consult with an electrician to ensure the proper connections are made.
No, # 10 wire is only rated at 30 amp maximum.
Answer for UK, Europe and countries running a 50 Hz supply service.It is acceptable to connect two 15-amp breakers to a 30-amp supply. It woud also be acceptable in some applications to connect three 15-amp breakers if it were known that the total current would not exceed 30 amps. For example in many UK properties there is a 60-amp supply, and connected to this there are two 30-amp supplies for the ring-circuit and the cooker, plus also a 10-amp lighting supply.

30
Yes as long as you change the 50 amp breaker to a 15 amp breaker. You will be hard pressed to get the 50 amp #6 wire under the terminals of the 15 amp receptacle.

Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.
Hi, I have the same question myself. I spoke to a electrician today he suggested I go with a new* 50 amp service in my camper do away with the old 30 Amp service all together off the new 50 amp service run 30 amp side of the breaker to my airconditioner or my stackable 220 washer/dryer combo and put couple other 15-20 amp breakers in my box for my lighting he suggested that way it also allows play for adding or modifying my breaker box as my needs change its always better to have more than not enough he quoted.... hope this helps a little
I greatly hope someone who has had personal experience with this comes to answer your question, but until they do I'm giving you my guesses. I think the problem will be the physical connection. I don't think you can physically connect your 50 amp male connector to the park's 30 amp female. That said, 50 amp service provides 220 volts. It's my understanding the the other 110 leg (that creates the 220) is only used to power a second air conditioner and also your 220 electric range/oven if you have one. If you don't have an 220 kitchen and don't need the second AC you can run your RV off a 30 amp service. To do this I think you will have to have someone who knows what they're doing wire a 50 amp to 30 amp adapter cable. I guess I'm kind of surprised 50 amp RVs don't come with a 30 amp adapter cable and instructions on how it can be used, but I don't own an RV so all this could be wrong.
The best way to answer this is to try both, then by an MK50H!
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
