Hi I am Don, when you plug into your house, please explain what kind of outlet you plug into? What I mean is, I have seen shore power adapters go from a 50 amp (4 prong) all the way down to a regular home out let (usually 15 amp)

I am using a three prong plug,like a dryer plug,adapted to a home outlet.We had it plugged in previously for about three weeks with no problem,but after returning from a camping outing this situation started.Thanks Steve
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
ok, I would be curious about what kind of load is drawn from the coach, either way. It may have gotten overloaded but that can take a while to become evident. when you plug in at home, what is ON inside the coach?

Customer reply replied 13 years ago
The condition occurs when only one overhead light is on,or when when the tv is on.
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
Do you have a generator?.

Customer reply replied 13 years ago
Yes,when we went camping last week we used it with no problem.
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
ok, try to simulate the situation with the gen on. The load (coach) doesn't know where it gets power from. Don't change anything, just unplug power and start gen

I just returned running the rv on generator power.No problems!Is my extension cord perhaps to small,even though it worked fine before?
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
well maybe, do you have to plug the shore power into a plug to get gen power or is it automatic?

I have to plug in.
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
Ok so you have to plug shore power into a plug to get gen power?
Ask Your Own RV Question
Customer reply replied 13 years ago
yes
RV Mechanic: OnanMan, Generator Tech replied 13 years ago
Ok, the problem is at the house. I hope you had a breaker installed in the circuit where you plug into the house. I would check all wires at the house plug and at the breaker panel, I suspect a loose neutral (white) wire.
