No 50 AMP on shore power

Thanks again everyone. I did move to a new location and everything works correctly here. Through this episode I learned something, thanks to you guys.

Because that is the breaker they use to power the EMS board. Doug

I too thought the progressive unit would alert you if you were not receiving a real 50 amp connection?

The Progressive unit will not give alert that L1 & L2 are bonded.
Otherwise it would have to give warning or cut power when a 30a adapter is used.

You said the outlet tests good.. I assume you measured 120 volts side to center (Top) from eitehr side.. Did you measure Side to Side? (should be 240 volts)

Some parks.. "Cheat" what they do is run just one leg, (Cause that what was there already back when it was a 30 amp site) and feed both legs with that one leg.

Your Intelletec EMS will read that as a 30 amp site.. Every time. In fact if everything inside the RV like Air Conditioners works, and works exactly as though you were on a 30 amps ties. this is the ONLY thing that can cause it other than a failure in the Intelletec EMS (And one such failure is a simple fuse, I think it's a 5 amp but it might be a 1/2 amp. )

I am connected through a portable Progressive surge protector which shows correct wiring and 50 amps. Everything works inside the MH but I cannot run both a/c units unless I turn off something (like the water heater). The transfer switch has no problem switching between genset and shore power. Something is just not letting 50 amps through.

The question remains..... do you have 240VAC across the two 50A hot leads on the pedestal??? It is a simple measurement with your VOM....please report. It is unknown, to me at least, if the Progressive protector would give an error condition to same phase voltage across those two points so it's showing of "correct" 50A service is inconclusive.

OP says quote:
It does seem that the problem is the wiring at the receptacle. I'll be moving to a new location tomorrow with good 50 amp at the pedestal and I'll know for sure. Thanks for the responses and suggestions. You guys are good!


SO time will tell. I too thought the progressive unit would alert you if you were not receiving a real 50 amp connection?
What Doug says makes sense to me so we see when he trys new hook up

Last to how the EMS system works
1. On 50 amp service, the AMP display goes dark as there is no reason to show or manage amp draw.
2. On Genset service, the display still shows amp draw and WILL shed load appliances if the load exceeds the amp supply of the Genset. Doug

Thanks everyone for the answers and suggestions. It does seem that the problem is the wiring at the receptacle. Tomorrow I move to another location with known good 50 amp at the pedestal and I'll know for sure. I've learned a lot from you guys on this site.

This would be an easy read and easy troubleshoot if we deleted all the name calling posts. Why can't you guys be civil to each other??? Just sayin' and shakin my head.....Dennis
