Might try re-posting cause what you posted is NOT making ANY sense.
Lacking comprehension

50A
2 HOTS (L1 & L2) Typically BLACK and RED wires
1 Neutral..WHITE wire
1 Ground..GREEN (or BARE) wire

50A Circuit breaker for EACH leg....one 50A for Black and one 50A for Red

Neutral MUST be on the correct 'slot' terminal at outlet
And ALL connections need to be clean/tight

Depending on where you are in some rural parts of the country and many areas in Florida you could have Delta High Leg 3 phase at a residence and you really need to know what your doing when working with it. Tie into the high leg and you will get odd readings and can burn out anything you plug into the 110 outlets you hook up to the high leg and neutral.

We deal with that in the Tampa Florida area and have to be careful of electricians who are not familiar with it as even on new construction in these old areas the pros get confused and wire a 110 outlet to the high leg. You go in to work on one of those homes and if you find a corded drill, saw, sander runs much faster than normal that you need to shut everything down before you burn your tools out and have the mains pulled until the situation is corrected.

There is also a Delta Low Leg that you could get in residential areas that will give you low voltage if a 110 outlet is wired to the low leg.

You may also want to run a new cable. 6 ga is required for 50A, not 8.

Example:
The power wire from the front ac makes the breaker panel power feed wires coming from the shore power have readings of 195v on one leg and 61v on the other in the coach when I hook it up but when I unhook it it goes back to normal, but when I hook up the wire for the water heater everything is ok and there is no change in the voltage readings.

First.. When it comes to electrical work if you have to ask you might consider hiring a professional to do it.. Doing it wrong is... Dangerous.

Now a 50 amp RV plug is wired the exact same as a 240 volt plug for a Range or other 4-wire appliance.

The only special concern is the NEUTRAL wire must be up for 50 amps same as the two HOT wires (Ground can be slightly smaller)

The odds of a Professional Electrican screwing up a 50 amp outlet are very very very low (I have seen it. blew fuses though)

With a 30 amp.. None of the above applies. The odds of a Pro screwing it up are over 50/50.

You are not communicating well. Think about what you are trying to convey: Break it up into short sentences that can't be misunderstood instead of a single long run-on sentence. Check your spelling before posting.

Does AC mean air conditioner or the 120 Volts?
Power doesn't come from air conditioners.

Confusing the people that are trying to help you does not improve your situation.

The other thing to consider is what condition were the bars in your houses electrical panel where you installed the new breaker. If they were dusty with mold and corrosion you may need to use a non-flammable electrical cleaner and be sure to use the correct paste to prevent corrosion between the bars and the breaker. You may get past this by re-seating the breaker in the houses breaker panel a few times.

Unused slots in electrical panels tend to get dusty, moldy and corroded over time so you do well to verify them using proper care though to not touch them while their live.
