After burning up TWO Automatic Transfer Switches in succession under Newell warranty as I was within the 24 months warranty that comes with buying a quailfying coach from Newell, they suggested I ALWAYS turn off the A/C before changing from shoreline to genset or vice versa. Five years later, still no problems. Just a little procedure to remember.

The explanation was that so much power is drawn by the A/C systems (my 2001 coach has two basement air units) that changing power sources with the A/C running will pull so much power through the switch that there could be arcing that burns the contact surfaces.
