New EMS shows Open Ground ?
Hey guys - was hoping some of you could check my sanity. Here at the house I have a 30A RV hookup next to the trailer. I plug the trailer in via an 30/50 amp adapter. I just completed the instal...

The N to G voltage of 1.3VAC would be abnormal if there is very little current in the Neutral wire. So if there is little or no Neutral current then that 1.3 VAC N to G is likely the problem.
So a 1.3V difference does not indicate a problem unless you know the entire circuit configuration.
BTW Trailers often have additional jacks touching the ground as welll as many MHs.
You are absolutely right if there are multiple services where the neutrals are daisy chained. In this case the OP has stated he has a 30Amp supply at his house. I have incorrectly assumed he has not daisy chained this service.
