Scratching My Head Over Electrical Problem

I'm currently on the road in New York. Yesterday, the power went out to all of the electrical outlets in the coach. The lights and front AC still work. I checked the GFI outlets and they can't be reset as it appears that they are not getting power. (I don't have a volt meter.) I'm running off the generator only at this point.

Here's the curious part - I turned off and on the circuit breakers in the panel. No help. When I'm running the AC and I shut off the circuit breaker for the AC, it continues to run. I shut off all of the circuit breakers and the AC and lights still work. Is this normal? Is there another set of breakers that I'm not aware of?

  • Thanks for all the responses. Turns out there's a second set of circuit breakers on the generator. One was flipped to off. Reset them both now all is good. :-)
  • I had an issue recently with my electrical system that seemed to be something wrong with the converter. Further investigation of the panel in my battery compartment that holds the solenoids for switching coach and chassis batteries, there are two sealed circuit breakers in there that look like normal 30 or 40 amp kind that reset on their own. I found a reset button on the sides of both breakers and everything worked again. 94 Bounder DP
  • Just for gen info, the lights work off of 12vdc and the front AC works off of the engine alternator/battery. Outlets within the coach are 120vac that work off of generator, inverter, or shore power.

    If only your interior outlets are not functioning, I too suggest you check the circuit breakers located on your inverter.

    Good luck

    I prefer load testers that will eliminate ghost voltage, but those are more expensive.
    Can't help you with coach diagrams, but what you have on board?
    Any manuals, picture of generator, transfer switch?

    On a 30 amp RV it is commone for the Generator to have two breakers..

    When ONe of them is 20 amp.. THis breaker feeds the A/C only (or the rear A/C if you have two) the other breaker feeds the rest of the house.

    If Microwave is dead, Fridge Switched to gas.. That breaker is suspect #1

    On RV's with Inverters.. There is a "Sub panel" this panel may be part of the inverter.. Often installed so it is hard to see. The breakers are usually PUSH BUTTON (push to reset)

    or it may be a second breaker box/panel as it is in my rig with standard breakers in it (Square D style).

    When on shore power the breaker for the A/C in the panel is switched by the Auto Transfer switch so IT supplies power to the generator which then feeds the A/C (This is per Intella-power's 30 amp diagram)

    When running Genny the Generator feeds the ATS un-protected power whcih is then returnd to the A/C via the 20 amp breaker on the Genny.

    Seems kind of Rube Goldburg to me but.. That's how they show it.

  • Check the circuit breakers on the INVERTER itself. These are separate from the breakers in your panel and do not affect power to your AC.
  • Generator circuits might have different circuit panel, or depend on generator breaker, meaning shore breakers are bypassed.
    We can guess in dark, but without tester and wiring diagram, it will still be just a guess.
