This EE agrees. Was this guy licensed to do the work he did? If so, you should be able to make a claim on his bond or insurance for the damage. If not, it's a lesson learned.
A family member did it who is a licensed HVAC technician. The wiring was fine. If you wire a 240v dual pole breaker to put out 120v, you will more than likely fail inspection.
Even a licensed electrician could have made this same mistake.
Had we knew ahead of time the camper required 110/120v, then the wiring could have been different for the dual pole breaker, but it still would have not be the correct way to wire it. Wiring a dual pole 240v breaker to output 110/120v is still incorrect, even if it works. Again.. you need the single pole 110/120v breaker to do it properly and pass inspection.
As stated previously, and I will continue to state this, if I had the single pole 120v breaker, it would have been fine.
Probably worth the expense to keep peace in the family then.
Two-pole breakers are used all the time to provide 120V. Dryers and ovens for example use 240 for heating elements and 120 for controls. A qualified electrician would have informed you that 2-poles were overkill for this application, and would have provided a 1-pole breaker. It is entirely possible to wire a 1-pole breaker and receptacle improperly and measure 120 V and even have the loads work properly. I see you never had it inspected. You may wish to have a non-family electrician look it over.

Everything seems to be working fine on the single pole 120v breaker. I'm happy to start living in the camper. I've been house hopping for a long time and renting rooms. I'm a single guy, so I don't care to have a big house to live in without a family of my own.
I gotta start doing research on camper living now.

There's a big difference.
This is one of the wrongest answers I have ever seen to any question. A 50 amp RV outlet is 120v/240v. Put a tester between L1 and L2 of any 50 amp pedestal and see, if you don't believe me.
Your S&B house is wired with 120v/240v. You use the 120v for lights, televisions, and stuff. You use the 240v for water heaters, stoves, and stuff. An RV is absolutely NO DIFFERENT. It uses the 120v for 120v stuff. If it has a 240v appliance, it uses the 240v. Most do not, but a few do.

Thanks for answering. Allen8106 was accusing me of being wrong. I was ignoring it as links were provided to show that 50A RVS are indeed 2 X 120 which if you can add, is 240. It’s important because facts matter.

Two lines with neutral are hardly worth arguing over?
What is being understated is the fact that each 50-amp L to N is rated 5/3rds the capacity of a simple 30 amp service. And it means the 2 L total capacity is 10/3rds the total available energy advantage over a single L to neutral 30 amp service.
The difference between a residential electrician and an industrial electrician is much like trying to compare a school nurse to am ER Trauma physician.

We'll have to disagree on that! The TT 30A receptacle is not made made to be wired for 220v so it was wired incorrectly.
http://www.myrv.us/Imgs/PDF/30-amp%20Service.pdf
"The TT–30 is a 30A, 120-volt recreational vehicle standard sometime it is called simply RV 30. Frequently it is confused for a NEMA 10–30 (see below) with disastrous results. Due to the appearance of the TT-30 plug, many people assume that it is to be wired for 240-volt, but this is a 120-volt device."
Again.. it was wired for 220v indoor appliances using a dual pole breaker. That has nothing to do with the recepticle . If we knew it required 110v , we would have went with the single pole which has a different wiring diagram.
As previously stated, if you have no advice on surge protectors or ways I can checkk for damaged appliances I respectfully ask you to please mind your own business and stop telling me it was wired wrong. I respectfully ask you to please mind your own business and stop telling me it was wired wrong. I know what caused the issue and it won’t happen again in the future .
It was wired wrong, plain and simple. Next time get a qualified person instead of an HVAC guy!

What part of 125 volts embossed in the connector is confusing?
As for surge protectors I have and recommend Progressive Industries and get the full EMS.

I keep hearing this and from professional electricians as well.
But I've seen many 240 volt 30 amp outlets that my TT-30 plug will fit.. I just know better and the RV itself knows better as well (Surge Guard hard wired type)
Home was where I park it. but alas the.
