How do I understand this. I unplugged the shoreline reset the gfi, let it rest awhile, came back and turned on the generator ( no shoreline) and ac worked fine.
Kind of complex for the why but simple enough for what we should do, perhaps.
The normal household outlet is 15 or 20 amp and adding a cord reduces the amount of power we can use, so the 15 amp "may" run the AC but not well and when on a long cord, not good at all and I never do it as it has a number of risks. One is that low voltage is tough on the AC and I sure don't want to ruin it!
Second point is that when we are running the generator, we find it lasts better if it has a nice full load on it. They are built to work, not loaf along on half work or none, so when it's running load it and AC is a good one as it is a semi-high load and you won't normally have enough in the RV to overload the generator if you don't work at with AC, hair drier, toaster,etc. at the same time.
Simple idea? Run on cord for things like lights, starting the frig to cool, etc. but for the AC, start the generator after unplugging and load it pretty much any way you want. Generator with AC, toaster, hair drier, etc will begin to trip some breaker to let you know to back off and try different. No harm, just a nuisance!
