30 amp breaker box really hot

Question

I have 2012 palomino puma 30 foot kfb travel trailer. Bought new used 7 months last year started fulltimeing again April this year in florida. About two weeks ago we lost shore power about two minutes bad storm. Then we noticed a hot smell coming from breaker box inside Rv. Checked shore power the 30 amp male Rv cord had burned right prong. The owners replaced burnt black wire in shore power. I replaced 30 amp male plug on Rv. Checked the battery the box holding the battery was full of water. Took care of that problem checked battery it was fine checked cells fine. Checked fuses in box fine. Replaced 40 amp fuses even though they looked ok. Still have hot smell in breaker box lights are bright in Rv 12 volt converter fan is working. Ac fridge are running fine. Totally stumped. Any one with an idea of what this could be please let's know.

I would pull the cover and check out the breakers. It's not uncommon for them to have loose cinch screws where the wires connect. You'll have to remove each breaker to check them thoroughly.
Also look at the converter section and see if anything looks burnt. Perhaps you had a surge go through the system during the storm.

Yes check ALL the wiring connections in your power panel.....AC & DC

Also check that converter DC output voltage.....should be 13.6V
Bright lights sounds like converter is putting out too much voltage

Get a Multi-meter!....then always check shore power voltage. Sounds like loose terminals to me.

You should probably make sure your RV fire insurance is up to date before the fire starts in your RV. In all reality, you should unplug your RV and get a qualified Electrician to look at the Rv's electrical system if you smell a burnt electrical smell and have to ask for suggestions from a forum full of total strangers.

Well I did have a master IBEW electrian (Retired) go through the breaker box fuse box he checked every breaker,fuse,nut,bolt,wire connection in the box. I switched to the 50 amp shore power with a 30 amp reducer. All looks smells fine. It appears the problem is in the 30 amp shore power I believe I was getting low ampage from that plug causing the burning hot smell. I have a power surge protector in the Rv when plugged into the 30 amp it was blinking red now that I switched to 50 amp with reducer it's solid red as its supposed to be. Thank you for your post. The reason I became a member on this forum is the wealth of knowledge from people that love RVing as much as I do. Once again thank you.
