It isn't the breaker. The entire wiring is wrong. This isn't on the guy selling breakers, it is on whoever wired the breaker and wired the outlet.

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.

The breakers have NO effect on the voltage. They do not combine two 120 volt lines into a single 240. They also do not divide some mythical 240 volt line into two 120 volt lines. A breaker is simply a thermally activated switch. It's only function is to turn the circuit off. A dual pole breaker turns two 120 volt lines off at the same time. The circuit was incorrectly wired. The fact an HVAC technician, (or plumber or rocket scientist) wired it doesn't change The FACT the the circuit was improperly wired. The breaker is innocent!
