Can not keep power going to house

[dstone]

We bought this 1995 Fleetwood jamboree a few weeks ago. Plugged it in at home and it worked fine, AC and everything. Then the breaker tripped repeatedly. Our neighbor, who is an electrician, put a new plug on the cable because it was fraying some. Worked at first only when we cut the breaker off in the house and in the motorhome before plugging it in then turned the breakers back on. Breaker in the house would still kick off periodically. Now the breaker will not stay on it all when we have the motorhome plugged in even though everything is turned off in the motorhome. What is going on? Any help would be appreciated.

Found the problem. Electrician checked the breaker and said it was fine, but he discovered water in the plug where extension cord and camper cord meet. Lesson learned is to always protect the plugs from moisture. Thanks for everyone's suggestions.

The breaker that TRIPS is the one that might be defective.
I think you said that is the one in the house.

After reading all the posts here, this is what I recommend.--

Hire an electrician to replace the 30 amp GFCI breaker in the house panel with a standard single pole 30 amp breaker. Several things in RVs can unnecessarily trip GFCI main circuits.

Check that the 30 amp receptacle is wired properly with 120 volts and correct polarity. With the receptacle mounted with the ground terminal at the 12 o'clock position, the flat blade terminal at the 7 o'clock position should be the "hot" wire and the flat terminal at the 5 o'clock position should be the "neutral" wire.

Then, turn all breakers off in the RV and plug in the shoreline cord and turn on power to it in the main house panel. Check for proper polarity in the RV panel to ensure the shoreline cord is wired properly. When all this is done, turn all RV panel breakers on and enjoy the electricity!

Offer the advice (not to) -or- (Yikes!) plug into the dryer outlet?..:h

I was about to post not to do that. Didn't have to because someone else already did.

The breaker in our house does have the test button. Will check the outlet tomorrow.

YOu should trust that your electrician friend would NOT install an incorrect plug.

Your breaker IS a GFI type and as was mentioned before, many RVs don't get along good with GFI circuits.

You REALLY need help from a professional here. If not your neighbor, then hire another licensed electrician.

I still recommend starting with a new breaker. Relatively cheap and easy. (But given your level of expertise, you should NOT attempt to do that yourself.)

It's fine. 125 is the max rating. Your 30A RV is 120 +/-

This bears repeating because proceeding in a logical step by step troubleshooting process is the only way to go.

Turn RV Main 30A breaker OFF
Turn House 30A breaker OFF
Plug RV 30A power cord int house 30A receptacle
Turn House 30A breaker ON

Does it turn/stay ON?
Yes..
Turn ALL breakers in RV OFF
Turn Main 30A breaker ON

Does house 30A breaker stay ON?
then turn individual rv breakers on one at time until house 30A breaker trips

If House 30A breaker trips with RV main 30A breaker OFF then need to check wiring on power cord new plug and connections in rv power panel

Process of elimination.
Starting with house 30A breaker---then rv power cord-----then rv power panel----then individual rv circuits

You said several things and failed to say one thing.

You did not say GFCI..

By code, an outdoor outlet (up to 20 amps) must be GFCI protected and in some places a 30 amp as well.. So far 50 amps' need not be GFCI.

IS THE BREAKER IN THE HOUSE a GFCI.. if so it will have a button marked TEST on it. pressing this button will trip it.

Many RV's do not play nice with GFCI outlets. there are many reasons for this, sometimes it is the converter, Some will trip a GFCI if the batteries are low, Others when they are full up, others any time, others never.

Other times the problem is somewhere else.

This is what I said in my original post. "Our neighbor, who is an electrician, put a new plug on the cable because it was fraying some." This plug I purchased at Lowes. Could that have been an incorrect plug? The breaker in our house does have the test button. Will check the outlet tomorrow.

It is 220 volts not 110.

Good luck.

Thanks for posting that. I was just about to do the same!

"I was just about to do the same".

BTW -
The OP has decided on the correct course of action for his level of expertise (call an electrician or mobile RV repair).
Good plan - nothing wrong with saying/admiting "dunno"?

Those who offered that/those suggestion/s - done good!..:C
