Yes, this is a very old park with old electrical pedestals BUT it shows 50-amp coming from the source. However, soon after arriving and hooking up, our coach went into inverting. We didn't know this at first but after a couple hours when my oven lights dimmed we checked the inverter panel saw it was inverting.
Trouble-shooting included changing to another post but on same pedestal as there are two coaches that can be hooked up to the same pedestal. After about an hour, It went to absorb and bulk and then float. However, this morning after a 36-degree night, with one heat pump, one electric heater, TV and of course refer, everything shut down and it went back to inverting. The circuit breaker had gone off outside on the pedestal.
Then, we changed inverter to 30-amp and pedestal to 30-amp and it went back to absorb and float.
The RV park says it is not their issue because 50-amp is coming off the pedestal. Could it be our coach's issue? It has never occured before.
Of course, Christmas Eve or a holiday week-end is always when issues occur. Right? What do you guys/gals say?

I think you are fine now with inverter max set at 30 amp and being on a 30 amp pedestal. You just won't be able to run 2 heat pumps, so use your Hydro Hot. Sounds like bad 50 amp pedestal wiring.

At best breakers are plus or minus 10%
Unless you have an amp probe to ck the actual amperage it is very hard to tell where the problem lies. My guess would be a weak breaker

By best quests would low voltage or loose wires in the pedestal plug. Your voltage and surge protector is going to drop the shore power is the voltage drops below a set voltage. If everything works ok off your in inverter and the 30 amp plug, it would appear that the problem is on the RV Park side, but their not going to admit it. Stay on the 30amp plug rum two electric heaters one on low and the other on hi. Should still power the refer and tv, or worst case freeze water bottles and put them in the refer side at night and turn the refer off at night to have more heating capacity

It would be more useful to know the voltage of each leg to neutral/ground (120 V) and between the two legs (240V) -- for the 50 amp service connection at the park pedestal Let us know.

Shirley this happened to us a couple of years ago at a park in Yuma. They insisted that the problem was with our coach and we called in a tech. After hours of searching for the problem and actually disconnecting the surge protector on our coach, the tech discovered that it was, after all, the park pedestal. They moved us to another site, the tech reconnected the surge protector, and the park had to make arrangements to rewire about 10 sites. The park paid for the tech.

Wondering if it could be a bad ground at the pedestal?
Yahoo Message Number: 113560 (http://groups.yahoo.com/neo/groups/country-coach-owners/conversations/messages/113560)
I can feel your pain. The park we are at had a major sewer back up and guess where it all ended up....right under and around our coach. Everything is so muddy we can't back out of here unless we call a tow truck, we would sink to the front axle if we tried. Good thing it's cold here for the next few days, keeps the smell down. We are listing a bit from front end sinking, haven't tried re-leveling yet. MERRY CHRISTMAS to all.

Most likely a bad receptacle, breaker or both.

Herb is right. Voltage at pedestal test is the first step. Don't the later Magnas have something like
our AC feeder output panels where we can watch the voltages on each leg under load?

Thank you for all the responses. We would like to think that it is the pedestal BUT another coach came in and is using the same pedestal at 50 amp without problem. Again this morning, still set at 30-amp, it went into inverting mode with a minor load.
The circuit breaker is not flipped at the post. After flipping the inverter breaker inside on the panel it has gone into the absorbing mode again (same routine as yesterday).
Question: is there a reset on the Magnum? If so, where? (BTW, an electrical issue on Christmas morning is nothing compared to the sewer issue mentioned here!)

With your last post, are you sure your not dialed into a 30 amp mode ?

Same pedestal. But did they try your outlet? It might be wired wrong or loose. Just an idea

Unplug shore power and run your generator. What happens then?

Posted that idea yesterday...running generator.

We are trying to troubleshoot the electrical problem. Running the generator yesterday would have obfuscated some data. One must carefully sneak up on the solution to her power issue.

One big difference between the 30 amp and 50 amp is the 30 amp on the pedestal is single phase - your power switch will connect the single phase to both legs in the RV when you plug into single phase, or keep them separate when you plug into two phase. So, perhaps there is some issue on the power switch on one leg? So, if everything is working off single phase (short of pulling more than 30 amps), then your RV is likely fine.
Also, don't assume a 50 amp on a nearby plug means yours is also Okay. I had one before where I was only getting one phase 120v with intemittent random voltage on the other - one of the lugs on the back on the 50 amp plug in the pedestal had never been tightened.

Moving slowly through steps usually proves faster and more precise.
Since he tripped a breaker on the inverter this time it is more likely issue is that breaker or internal to the inverter. Either ignoring the power share setting or something heating up until resistance pulls too many amps and breaker trips.

Be careful if the pedestal has a floating 50A neutral (Which might be your problem with the pedistal), If the coach is connected to a floating neutral, high or low voltages can result in different parts of the coach, varies with load attached to L1 and L2. This can be very damaging to RV equipment.

Could also be a bad house battery, calling for high rates of charge. Thus exceeding available power.

Haven't seen this discussed here, but am I the only one who won't plug my expensive coach electrical system into any strangers power pole without first testing the pole/circuit. I know CC's have good built in protection, but if bad power is going to blow something I'd rather have it be an external tester than internal systems. It would also immediately rule out the pole as the source of these problems in the coach. Buy a tester or make one, but test before you trust.
