I automatically shut down the generator if the campground is dusty (dirt / gravel) so that I do not cause a dust storm. Then as soon as I get plugged in, I start the ACs up again.



Along the same lines, if I am hooked up to 50 AMP service and I turn on the generator to exercise it, should I shut off the AC system?



I have read the manual but it doesn't really address these two questions.



THanks in advance for your assistance.

You probably have an automatic transfer switch for switching service between shore power and generator. Most likely it is set up as generator priority. That is if you are both plugged into 50 amp and have the generator running, you will by priority be using the generator. When the generator goes off the ATS will seamlessly transfer to shore power. However, the less amperage you are drawing at the time of switchover, the easier it is on the transfer switch and will prolong its life.
