One leg AC down 2008 Tiffin

Hello
Thanks to anyone who can help. Here's the situation.

No power to half our AC outlets with either generator or shore power. All interior breakers are set. Only clues are that the problem occurred while on generator power and one of the two 30 amp breakers on the generator was tripped. Resetting the breaker did not get power to the dead outlets.
My first thought is the coach wiring exiting the transfer switch (both previously replaced by me). That means removing about twenty screws in a cramped bay with wire stiff as my walking stick. Any quick work arounds?



Extra points to Old Tiffin: outlets are staggered; converter has regular 110 plug; bay has good and bad outlet => you can have DC no matter which leg you loose.

Pull the cover off the breaker box and check for power at the breaker, that's usually only a screw or two.

Have you for sure checked both legs, often inverter breaker can trip owner might think one leg is down.
Also a hidden GFCI feeding outlets down the line has given owners fits. The not so great stab in wire connection for outlets in chain can fail.

One leg AC down 2008 Tiffin

I agree with you, sounds like the wiring exiting the switch, double check everything you did for good connections and tightness.

Hopefully somethingís not burned open, or maybe the wire came out of the connection completely somehow and temporarily shorted, thats all I can think of right now as to explain the breaker tripping, then not but dead leg.

what about GFCI ? In my coach half the outlets can pop. Also, in my coach anyway the inverter is in line with shore power/genny and as mentioned if the inverter has a popped breaker or worst case a melted ac out circuit, it can act exactly like this. Don't ask me how I know this.

If you have an inverter/charger much of one leg will go thru that. It has breakers on it, look in the compartment for it.

I believe my 2008 has a converter/charger. Would an inverter show the same performance? Seems to be working fine now that I switched outlets. All GFCI circuits are working normally. Two screws on breaker box sounds like first check. tomorrow.
Thanks
Tom

Check your power management display, that should tell you what power is coming in and available to use and then trouble shoot from there.

Try to reset your inverter. Had a similar situation happen to me. Reset the inverter and all is well.

He says he has a converter not a inverter.

To Old Biscuit's question.
Some poor writing on my part. My post would make a little more sense if the text you highlighted immediately followed the converter sentence.

I believe my 2008 has a converter/charger. Seems to be working fine now that I switched outlets.
The converter uses a standard 120V wall outlet style plug.It is in a storage bay with two 120V wall outlets. Since the converter was on the dead 120V leg we had to run the engine to charge the house batteries. The outlets in the converter bay were on different 120V legs. Battery charging was restored simply by switching outlets.

Situation solved. Someone suggested hitting the main breaker with a screw driver. I Tried; no luck. Tried to replace breaker with equivalent. Did not fit. Decided to plug old breaker back in => every thing works fine. Just to be safe, I'll probably look on the salvage market to get some of the correct breakers. Thanks to all.

They mostly used home breakers. Some more popular than others. RV salvage is high. The breaker model number may be on the panels tag. If panel type was phased out ,likely find NOS on EBay or supply houses online. Radwell buys up lots of discontinued old stock.
