just how we do it

we never have the shore power and generator on at the same time, however your transferswitch should switch it over. But don't see any reason to have both on. The few minutes between shutting of the generator and hooking up shore power is not worth it if there is any problems.

All power going to the RV should be shut off first, that includes the gen. That will help save the transfer switch.

Hi and welcome to the forum.

Technically, it's OK to allow the transfer switch to handle the switch over but many of us don't do it... especially when there's a heavy load such as AC running... to avoid slamming the switch too hard and maybe leading to premature failure.

Shutting every thing down may save the contacts from arcing in TS if you forgot the AC was on or some other high amperage draw.

Thanks to all

Will now shut off gen prior to throwing the switch on shore power. Just replaced the transfer switch in Ind. we may have been part of the problem. All that said, what a great group at Newmar. Would never buy from someone else!!!

The Auto Transfer switch is designed to CONNECT to power, but.. When it comes to disconnecting.. It's not such a good idea.

So here is the procedure for plugging in to shore power.

Turn off as much as possible (Air Conditioner, Water heater, , Televisons and radios)

Shut off Generator, allow to die

(Switch should "Release" at this time, on some (IE: The one I have) This transfers to shore power)

TURN OFF breaker on post.. PLUG IN, Turn breaker back on.

Then turn your A/C, water heater, etc back on.
Home is where I park it!

I shut everything off then kill the gen before switching shore power on. A little more work but better than arcing something.
