It shouldn't have been an issue if the Automatic Transfer Switch was working properly. And it doesn't sound like yours was. The sizzling you heard was probably coming from the switch box.
There was a big recall some years back for a certain brand of transfer switches, and it's possible that yours was on the list, but never got changed out.
Best thing to do is to dig out your paperwork and ascertain whether you can start and run the generator if plugged into shore power. Even if it shouldn't hurt anything, it's a bad habit to get into.
I would certainly take it to a knowledgeable shop/individual and have it checked out thoroughly. With any luck the only thing damaged was the switch.
You know what they say: "Stuff happens".
Thanks for responding. I'm shocked it let us use both until turning on the AC. That's when it messed things up. We learned the hard way but it will not happen again. Now to get her fixed...
