50 a cord

Ok op org post said works with 20 amps now I’m reading 30mp Given this it sounds like an open neutral

Send us you reasoning!

Send us you reasoning!

Sorry I was wrong on the open neutral. Here is what I think is the issue
When you connect the 30 amp adapter you’re taking the one 30amp 220 lead and feeding both 50amps legs of the coach. Hard to say without actually checking it ,but if “everything works” with the 30 amp adapter as the op is saying then it really indicates a problem with the pedestal. I say this because the 30 amp adapter is getting 220 to the 50 amp plug if everything works. And if both 50 amp circuits in the coach are getting power from this arrangement , it indicates when the op plugs the 50 amp plug in to the pedestal one of the 220v circuits for the 50 amps is dead. What are your thoughts?

This may help explain

Ok!

You asked to many questions!

I personally don't have a dogbone. That means I have to guess. But it would make sense to connect l1 and l2 to the hot leg of the 30 amp service to make power available all through the coach. Because I don't have a dogbone I can't test to verify my assumption.

The neutral on a 220 or above voltage system is what makes 110 or 277 in industrial systems.

If on a MH with 50 amp service an open neutral could serve up 220 volts and fry anything connected to it, but that is not what we have here.

This is what I think has happened!

Last summer was brutal and service was stressed! Not the 30 amp service, rather the 50 amp service. Breakers tripped often, and failed. My guess is many 50 amp pedestals were not serviced afterwards as they should have been. That is why the 30 amp works, and the 50 doesn't at more than one space.

A serge protector, or multi meter could prove me right or wrong, but that is where I would look. I am so glad I do it off grid!!! I never expect to much, and never disappointed with accommodations.

Clarification: RV 50A power, is actually 2 legs of 120V electricity.
YES they add up to 240V but they are separate.
30A RV power is 120V, (110).
Ask anyone that wired their own 30A RV service with 240V. They'll show you a big bill for the repairs.

Mark! Let's not confuse anybody. The reality is 110 is a 220 circuit divided into two 110 circuits via a common center tapped transformers secondary winding.

There really is no two 110 circuits. They are 220 circuit divided into 110.

We can talk semantics all day. However, to the average homeowner 120V is for outlets and 240V is for appliances and welders. If you wire a 30A RV plug with two legs of 110 3 wire, you're buying a whole bunch of trouble.

I actually saw this happen. It was a family reunion and cousin Floyd was a millwright at the local lumber mill so we had all of these motorhomes coming in and he decided he was going to run some extension cords from the barn out to the various motorhomes. He looked at the plugs and assumed that it was 220 and wired it accordingly my father-in-law‘s motorhome blew up just about every electrical item in the couch. Not a pretty sight there were sparks flying from the microwave.

Semantics? OK!
So do you know the difference between a apprentice, a tech, and a handyman?

I’ll bite…..no

One does their job under the supervision of someone that knows what there doing.
Any confusion in your mind about what is going on, when dealing with electrical is dangerous, and should be left to the pros.
