Electrical Problem

[Kelasn]

I have a 2009 Sportcoach Legend.
It has a ME2012 inverter with 2-15 amp output circuit breakers with 30 amp fuse.
It has 2 GFI outlets 1-kitchen which controls one side outlets, 2-bathroom that controls other side.
At pedestal, 50amp shore power has the expensive progressive surge protector, checks out fine no issues at pedestal.

Issue:
Bathroom GFI tripped along with 1 of the inverter's 15amp breakers. I Pushed inverter breaker that allowed the bathroom GFI to reset. Within 12 hours it happened again. This time the inverter breaker seems ok but GFI won't reset. Checked the main breaker box under bed and all breakers test fine and are working properly. Checked all lines coming into the GFI and have no power zero on all lines. Checked all dead outlets and no power zero coming into all dead outlets. Checked under bed to trace bathroom GFI breaker line to determine where it goes from main breaker and appears to go to inverter and out into the coach. In rear bedroom there appears to be two outlets that are directly connected not on daisy chain, one works but the other does not. Not sure where the break in power could be occurring. Appears the inverter is working properly but did a reset just in case, still no power to bathroom GFI or side of RV. Any ideas would be most appreciated. Thanks Kelasn

Have electric to main box and have electric out of all breakers.

Do you have electric out of Invertor?

Do you have electric to the GFI?

Is the GFI good? if you have electric to it it will either reset or is bad...........from what you are describing the GFI is bad.

This is just a Best Guess as you are the one doing the testing, But as what you have said involves the Inverter or the GFI the issue must be in one or the other.

Test and get back to us - let us know either way.

Best of Luck,

Did you check the output power from ALL of the breakers in the main electrical panel under the bed? If all of them have power out and you still have no power going to your GFI outlet, then you may have a wiring problem.
Also make sure that you also have power out of BOTH inverter output circuits.

I'm curious how you know there's no power to the GFCI?
Unless you pulled it out and checked the input power to it, there's on way to know if there's no power or if the GFCI is just dead - which is common.
I would pull the GFCI and check for power. If it's there then you just need to replace it. It's a common residential part so you can get it at Home Depot, etc.

Larry, if I read the OPs statement correct "Checked all lines coming into the GFI and have no power zero on all lines" there is no power to the GFI. In that case I don't think disconnecting the load will solve anything.

Typically, when you have a GFCI, there are outlets "downstream" that are fed from the GFCI. Any of those downstream outlets can trip the GFCI outlet. If you pull the GFCI, you will see that it is labeled with "LINE" and "LOAD" attachment screws. If you disconnect the LOAD wires, you may be able to reset the breaker and/or the GFCI. If that works, your problem is with one of the downstream outlets. Only solution is to pull those outlets, one at a time, and disconnect them from the circuit and then retest the GFCI reset. You may find the problem by visual examination while doing this. (As in wet, or corroded wire on the offending outlet)
