Shore Power vs Generator

Quick question 99 U270
If the generator is started while the coach is plugged into shore power, does the coach remain on shore power or does it switch to the onboard generator supplied power?
thanks

Different coaches have the ats wired differently some generator default some shore power. You just have to figure it out. If you are on shore and start the generator and the voltage changes the generator is the primary.

Craneman is correct again.  On our '99 U-320 the shore power is primary and generator secondary.  (inverter is tertiary)

If you pop the lid off the shore/genny ATS you will find a wiring diagram.  It will indicate which "input" is primary.  Then you just have to determine what AC source is connected to that input.  Easy to do - plug into shore power, or start the generator, and carefully check which input is hot.

OR, see this page at beamalarm.com:

Thanks for this thread. I checked our coach, and it says that the generator is primary. With that in mind, then, tomorrow I'll turn the big loads off, start the generator, unplug from shore power, then turn on the major loads. Then when we get to the campground, I'll turn off the major loads, plug in, shut off the generator, and turn on the major loads. That should keep the microwave clock on without any interruption. We'll see how it goes tomorrow.

 ;) That reminds me of Barry's posts. We would go on and on regarding some issue or another with everyone offering up a potential solution and eventually Barry would chime in with a quick reference to his site with the exact answer we were looking for!

You're inverter should be able to keep the clock on without any problems. Unless your microwave isn't run through the inverter circuit?

I generally leave the inverter off unless actually using it. Once in a while we have one of those nice travel days that we don't need the generator, so then I'll use the inverter.

"I'm curious David......... what happens if the clock goes off?" Jo Ann doesn't know when to make dinner and then I get grumpy.

It's always best practice not use both power sources simultaneously.  Turn off big loads, then turn off the source being used, then start the new source.

Hey Guys, the clock, when I am in the coach, time does not apply, clock starts or stops means nothing when the U-line keeps the ice coming and the old Domestic refrigerator has a supply of cool ones.
My life at work is all clock driven, down time is slow time, late breakfasts, late dinners, or no dinners at all. Nice music playing, 60's, 70's 80's, some good jazz, sounds of New Orleans and a good book. 
We all need to meet when the world gets back to normal and figure out this clock thing!!
