Hot circuit breaker at power pedestal

The 30 amp circuit breaker kept cutting off even though I wasn’t exceeding 30amps. I could not run my ac and my hot water heater without tripping the breaker at the pedestal. This has never happened in the four years we have had our Motorhome. I switched to propane for hot water and everything was ok after that. I felt the pedestal circuit breaker and it was hotter than usual. The circuit breaker was lose in the breaker box and my rv plug was loser than normal in the pedestal plug. Was the breaker faulty or did my motorhome draw to many amps causing the breaker to trip?

Old worn-out breaker, maybe bad box. Get campground mgmt to fix asap or switch sites.

Probably a bad receptacle and/or breaker in the pedestal. Let the office know about it.

My MH is 30 amps. I carry a 50 to 30 adapter with me. When I plug into the pedestal, if the 30 amp receptacle seems loose, I'll use my adapter and plug into the 50 amp receptacle. (Note - I also carry a 20 to 30 amp adapter, AND a 25 ft 30 amp extension cord)

ALSO - I carry a spare 30 amp plug. If the pedestal receptacle is bad, it can damage your plug. If the blades on your plug look like they have arcing or overheated, change your plug.

It won't do MACH 2, but I can get a sandwich and take a pee.

If you were running AC and Water heater, you probably were on the edge of drawing too much. You said that when you switched to propane for the WH, the problem went away. Just a learning moment. Don't try the microwave when AC is running either. When on 30A you have to manage your use of the big draw items.
I stayed at a state park and the 30 A was acting up. The park ranger came out and replaced the receptacle - she said it was the first thing she learned how to do.

Since the pedestal CB was hot to touch you need to MOVE IMMEDIATELY to a new site. CBs that repeatedly trip become weaker and weaker causing them to trip at lower draws. With it HOT you are in danger of getting improper voltage which will cause electrical problems in your unit.

Like others have said - if the receptacle is loose when I plug in I move, I don't put a reducer on, I move.

Be safe - Richard

After getting the thing checked or if they are reluctant to do so try shading the box. A breaker loses a lot of its capacity ( breaking point? ), when they get hot.

Breakers get tired over time and do need to be replaced if getting finniky.

Check the Plug on your shore power Cable, Same thing happened to us this winter it turned out to be caused by our plug end being slightly damaged causing minor arcing inside it resulting in excess draw changed plug on cord Bam problem solved, you may want to change the plug head even if it is the pedestal and they repair it as that could cause damage to the shore power plug as well that may not be immediately apparent
