50 amp shore power issue

I really doubt it’s the pedestal, this happened last time out and I assumed that time it was the pedestal. I’m thinking one leg isn’t working but I’m about as far from an electrician as is possible.

I speculate pedestal issue.

Sure sounds like one leg of the 50 amp is not there or your plug or somewhere back from there is open. Such as a breaker on your own AC panel.

Cavie has it nailed. You need a voltmeter. Everyone that owns an RV should learn how to use a voltmeter with confidence. They really are quite simple, but very confusing with all those weird symbols.

I told my brother to take pictures of his as I was teaching him. He did not nor did he mark his voltmeter to remember what position to put it on. I will be putting on a class again for him and he will take pictures.

Working with adapter would show to me that the source is bad. Try resetting the circuit breaker at the source panel.

Thanks, I’ll have to get a volt meter

Do you have an inverter to power parts of the rig? It could have a tripped breaker.
Is the rig fitted with an energy management center? It could be set to thirty amp.
Are you sure the source has 120/240 output. Test as described by previous poster.

2015 Fuzion, when plugged into 50 amp shore power I am not getting power to most appliances (but bedroom AC will run). When using 50/30 adapter I can power the AC and all appliances normally. When running on generator power all works normally. Any idea why I am only getting partial power on 50 amp shore power?

Start at the shore power with a volt meter. Measure 240 volts L1 to L2. 120 volts L1 to neutral and L2 to neutral. Measure every connection back to the main breaker. IN THAT ORDER.
