This is so strange..Plugged in to 30 amp shore power. Went to use microwave. As soon as the magnetron fires up, the lights and control panel on the microwave dim to the point of not working.Used an extension cord to plug the microwave into another outlet in the RV and it works fine.I figured it was loose wiring in the outlet, (sometimes those wires come loose from the crimp), but that was a no-go.Now the strange part. If I fire up the generator, it all works well.No other outlets in the MH are affected, just this one.Any Ideas?Dan

Sounds like a problem with the pedestal. Re-cycle the 30 amp breaker, make sure both sides are on and if still fubar, call the park manager.

The microwave may be a thousand watts potential. Use the DW's hair dryer to approximate the same degree of load on other outlets.

Check the wire connection at the breaker (and the breaker itself) for the Microwave circuit. From the way you describe the issue it pretty much narrows it down to that area.

OK. Got a hair Dryer, works fine in all outlets EXCEPT microwave outlet. Will work on fan only, but as soon as you kick on some heat, It acts like the microwave did. Slows down to nothing. all other outlets in RV are fine.Not a pedestal problem, as I am back home and still acting the same.Will check tomorrow on the breaker issue, but not holding out much hope on it. The outlet works fine on Generator, just conks out on shore power.Thanks for everyones input! Truly appreciated.Dan

Some rigs have the microwave and water heater on the same branch circuit and use an energy management device to make sure the two devices don't overload the circuit when they both want to run. If you have one of these devices, that's another thing to be suspicious of. The generator vs. shore power behavior difference is very mysterious, however.
