120V Learning Experience

I'm posting this hoping it might save someone some day if they are in a similar situation.

Last night we went "Wally Docking" about 60 miles from home because my daughter had volleyball practice until 9pm and a game at 8am. There's a Wal Mart 1-2 miles from the gymnasium.

It was a little cold so I was running a small space heater and had the TV on - running from the generator. After practice my wife decided to make some microwave popcorn the same time my son decided to toast a bagel. Keep in mind the space heater was still on along with the TV and a phone or two plugged into wall chargers. About two seconds after my son turned on the toaster over - POOF. We lost all 120V . The generator was still running and we had 12V.

I immediately just KNEW we had blown one of the coach circuit breakers but when I checked them they were all good. I tripped them all one-by-one just to make sure. They were all good...Hmmmm. Well I figured maybe we tripped the GFI somehow. I checked it and it had not tripped. Stumped I figured I would just have to figure it out in the morning.

I checked and re-checked all the coach breakers this morning and deduced we must have blown something in the converter or the main circuit breaker was bad. When I got home I decided I should plug into shore power just to prove it was the converter...and shore power WORKED .

It was THEN I remembered the generator has a 30 amp breaker just below the start switch. Reset that breaker, fired up the generator and... I now have 120V from the generator again.

So if you're ever RVing somewhere and lose all 120V while running the generator, check the [ Moderator Edit ] frigging generator circuit breaker first!

Very common occurrence when running the Genny. Always check Genny breakers first.

Our GFCI is always tripping. The hair dryer, microwave and toaster requires a lot of power.

My genny has two thirty amp breakers. Oddly when I run a vacuum (that is the only thing on) invariably the same genny breaker trips. This has happened twice when I am cleaning after our winter travels and before I put it away for a while. If I reset and try again it trips again, with just the vaccum running. If I change circuits, same thing. Twice I have had the generator output checked under load when in for normal service and it is operating like it should.

I think that breaker is weak but as usual I never think of it again until it happens again. Otherwise my generator runs fine and handles the load of two ac's just fine.

Weird.

That means the last appliance to be plugged in is the culprit, and has a voltage leak. It does not mean you are using too much amperage.

It very well could be the vacuum has a short or something. Have you tried using the vacuum while on shore power or in a sticks and bricks?

You mean that jennies actually are there to supply power? I thought mine was for ballast... just kidding. Been there and done that.. learned a while back to always check the jennie breaker(s) first....
