New transfer switch
#1

 Just got 701 back from factory with a new transfer switch.. One noticeable difference. The time it takes from turning off the generator till the shore power engaging. It used to take 45 secs to a minute.. Now takes less than 10 secs..

Less time without the A/C = Happiness...

Not a good idea to turn the gen off with the AC running. Bestgenman educated me on that one. The generator control mechanism doesn't know the engine is shutdown, and tries to maintain the voltage while the engine is shutting down. It puts undue strain on the generator. Plus it can cause arcing and pitting of the contacts in the transfer switch if switching under the heavy load of the ACs.

Marc, that 45 sec delay is usually the protection system going through it's routine of checking out the voltage, frequency, and polarity before allowing the coach to connect to shore power. Perhaps, the software is now quicker. But do check to ensure you still have a voltage protection system.

My time to switch over is about 10 seconds at most. I ALWAYS turn OFF ALL high loads before shutting down Genny, including A/C's and AH.

Be cool if there was a master switch to turn all power to act off at one time

It would be, BUT switches designed to switch under heavy amperage loads are different than the normal contacts. They have to be designed to handle the arc that happens as the contact points get close but not quite touching. That arc causes the contacts to pit and oxidize which leads to poor conductivity.
