50 AMP circuit breaker

Do you have a large inverter? Check to see if the breakers are energized. Some have a small reset button with a white or red end.

good call exactly what I was thinking.

rgatijnet -

Thanks for your input. I need all the help I can get.

I started this discussion in the middle of this problem I am having. I’m going to go back to day one.
The MH we are talking about is a 2002 Monaco Diplomat 36 ft. diesel pusher. I bought it in 2009. (original GFCI lasted 12 years ) In February 2014 the vanity GFCI tripped a couple times. OK. The coach is 12 years old. I replaced the vanity GFCI. It lasted one year. February this year it tripped at first every once and a while. During this time I bought an outlet tester. You all know the one it is I bet. Two yellows lit up showing everything correct. This tester also has a button on it to push to test the GFCIs. It also worked tripping both GFCIs. With in a few days the vanity GFCI would trip sometimes after 15 minutes to sometimes it would stay reset for two hours before tripping. It wasn’t many days and it would trip repeatedly to where I am now where it won’t reset at all. In my feeble mind this almost looks like a computer virus ( kidding of course ) Starts with a simple GFCI and winds up turning the electrical system into dust. The original vanity GFCI was 15 AMP. I replaced it last year with a 15 AMP GFCI. Then this year I was told by some know it all to put in a 20 AMP GFCI to match the 20 AMP CB it was on. That didn’t change anything.

You have something that is failing. It could be the 120 volt element in your refer, an outlet that is getting moisture in it or bad wiring.
Locate the other receptacles that are connected to the GFCI in question. Un plug all equipment in the circuit and test it again.
There is no problem using the 15 amp GFCI receptacle on the 20 amp breaker. There is better quality GFCI receptacles. Cheapie ones are not always your friend.

OP says Quote:
Why no current to any outlets when plugged into shore power when all breakers read 244 and 122 ? TS is sending current to CB panel.


So I ask what would a bad fridge heater ever have to do with this power loss??
It has to be a Inverter problem as in no flow though inverter so either bad inverter breaker or bad inverter
the gen set may run some outlets because it may be wired in a way as to those outlets are not run through the inverter while on gen set
(non invertion run plugs)

Here is the inverter I have :

Kinda hidden from view by the black cover is what looks like a 20 AMP fuse. It is white with 20 on it. I took the nut off it, but it didn't seem like it wanted to come out. I didn't force it. It has always been lose and didn't feel like it was anything to reset. It's always been that way.

One of the first things I did 3 weeks ago was unplug everything. ( the microwave, water heater, two on the fridge ). It didn't make any difference. The only things I didn't unplug were the front and bedroom TVs due to their un-accessibility.

I have the same inverter as you do. If the transfer switch clicks(make sure this is happening) when you are hooked to shore power then it appears that you are losing power as it comes in to your coach. On the front or side of some Xantrex inverters(the D models) are THREE circuit breakers. The two lever type circuit breakers(may be on the front or side) control the power in to your coach and the single push button circuit breaker (the white one with the "20" on it)supplies power to the battery charger portion of your inverter.
The two lever type circuit breakers supply power to your main circuit breaker in your electrical panel inside the coach. There is also power that comes in to your coach that bypasses your inverter and goes directly to your AC and SOMETIMES to the microwave outlet and electric water heater.
Once the power goes through your inverter or if it bypasses your inverter, that electric is run through your main electric panel and routed out to the separate circuits managed by individual circuit breakers. It is unusual but circuit breakers do go bad.
You need to start at the beginning and check everything from the shore power pole on in.

The small white 20 is the circuit breaker for the inverter. If it is tripped it would stick out about .5 inches. You do not need to remove nut. That is holding the circuit breaker in the case.
OP gave readings of across the main and to ground. Some rigs supply 120 volt refer power through the inverter, not many but some.
Rgatijnet1 gave some good info for the same inverter.

you say you have no power? what does unplugging things have to do with finding out why there is no power or was that when u had power and was a simple gfi tripping

Thanks to all that have responded. I’m going to start with what works. I have two GFCIs in the coach. One on the bathroom vanity and the other one under the dining table. When I start the generator all outlets on the dining room GFCI work. The vanity GFCI ( new ) will not reset so there is no power to the outlets on that GFCI.

To deandec… yes to everything.
To enblethen ……244 and 122 at the breakers. All 50 - 30 - and 20 AMP breakers are on with 244 and 122 volts flowing thru.

I took the cover off the transfer switch. I had my wife start the generator while I am at the TS. I heard it “switch” and the green light came on. I shut the generator off ( already unplugged from shore power ). I turned the inverter on and I get no volts at the TS or CBs. I think we are getting zeroed in but the mystery to me remains why current flows thru the dining GFCI when the generator is on but not to the vanity GFCI ? Why no current to any outlets when plugged into shore power when all breakers read 244 and 122 ? TS is sending current to CB panel. Could the TS not switching to invert be the cause of all this?

your breaker is tripped on your inverter or your inverter is bad
I had to bypass my neigbours inverter because there was no flow through power when on shore power but I never tried it on gen power.As it turns out the 120V sensor was bad in the inverter
Do you have two 120V circuts flowing through your inverter or one?

Verify that the inverter is turned on.
Unplugging other items from GFCI protected receptacles, could allow for the GFCI to reset if it is not resetting do to fault condition. That is if you have not checked the line side of the GFCI for power from the source whether it be from inverter or 120 volt AC distribution panel.
