Does Generators provide power to all outlets?

So this passed week Northern California has a power outage for a few days and we had a chance to try the generator in our 2016 38' Adventurer Class A MH. It is new to us, so this whole experience was a good test of our rig and its boondocking capabilities...

It all worked out great and was very helpful during the power outage. But we did notice something odd. It seems all the power outlets in the MH did not work. In fact, most seemed not to function while others did. Namely the one next to the bed where I plug my CPAP mcahine into was not fucntioning...

Is this normal?

Maybe and maybe not. Depends on how the rig is wired. All of mine work all the time either from shore power, generator or inverter.

No, that would not be normal. Did you check all your breakers, including the inverter?
Not sure how yours is set up but I have two panels, one for AC and one for the inverter.
GFCI plugs, found in weird places, at times can trip and not be apparent.
If you have GFCI breakers they take the place of GFCI plugs.

Just my limited knowledge of the power system in a MH.

Good luck

The quick answer is that the generator should supply all the outlets that are powered when you are hooked up to shore power.

Mr. D's comment is telling you to take a look for 2 circuit breaker panels - one of them only passes power from the shore power cord and generator, the other passes power from those AND from your *inverter* when you have neither shore power nor the generator running. The inverter takes 12vDC from your "house" batteries and turns it into a limited amount of 120vAC - and usually the inverter powers things you'd use during quiet time in a camp ground, like the TVs, DVD player, satellite receiver, and probably a couple of outlets for charging phones or powering medical devices like CPAP machines when shore power is unavailable.

The inverter has circuit breakers on the device itself, usually the little "pop out" button breakers, and often they are on the side of the inverter you can't see from the front of the device. Depending on the exact model of inverter, you should have a breaker or fuse on the battery side and a breaker(s) on the 120v output side. The inverter has a "pass through" function that kicks in when you are on shore power or the generator. The likely places to check are the 120v output breaker on the inverter and the circuit breaker(s) in the breaker box that is powered by the inverter.

If in doubt, call your coach builder (Winnebago?) and ask. If it's Winnie, they're very good with things like this.

Also I suggest you go to your "User CP" (control panel) and "edit signature". In your 3 lines of text you can put the year, make and model of your RV so you don't have to type it every time you have a question or problem and the rest of us won't have to ask. It will help others help you. http://www.irv2.com/forums/usercp.php

Good luck and safe travels.

Check and reset your gfci. Also check the 2 circuit breakers that look like light switches on the side of the generator.

...more simply said--"usually" generator or shore power will power all plugs in a Class A. Inverting off battery bank often limits power to only a few plugs. One exception to this might be that a smaller generator would/might be wired differently. So sounds like something is amiss with your rig.....

My guess is GFCI too, especially if they are on same wall inline with eachother. One poster had one in bay with inside outlets on load side of GFCI.

Might also check to make sure both breakers on the generator are on. GFCI is a better guess but worth a shot.

I had one GFI 120 volt power plug tripped in back of coach and it was culprit for three others not working. Pushed reset and no more issues . All plugs work off generator.

Agree you either have a tripped GFI or the generator breaker is tripped and you are getting power from the inverter only. Needs further diagnosis for sure.

Agreed it's probably the GFCI. If you look around the galley or maybe in the bathroom for a wall outlet, you'll find it there. It will have a test and a reset button. Reset it.

When this GFCI trips in our MH it cuts power to three different outlets but all the others work fine. Also if we turn ON our inverter it only supplies power to 4 outlets but we only have 1000 watt inverter too.

So more than likely when you lost power and then started up your genset, that tripped the GFCI outlet knocking out a few other outlets.

have to disagree that GFIC is the issue ...probably need more info from OP here but OP's post seems to suggest that all works fine on shore power but not on genset--if so, a "tripped" GFIC isn't the issue...
