"Plug In" generator transfer switch/relay?

You only need to go out and plug it in to the camp ground pole. When you unplug, plug into the generator. When you want to use the generator it will already be plugged in.

I'm sure you can find an electrician to install it. But, is it worth the $$$? I just leave my cord plugged into the generator receptacle any time I am not hooked to shore power. When I unhook and stow the cable, I just plug it in. If I don't need generator power, the cable is just stowed. But, if I need generator power, I just hit the dash button.

You could 'ADD' a standard auto transfer switch.


That receptacle is the generator power out.....
You plug our RV Power Cord into it for gen power


The auto transfer switch...
Remove that gen outlet and replace with a junction box
Then wire from junction box to 'GEN-IN' on transfer switch (OR short power cord from Gen Outlet to transfer switch)
Then OEM Power cord to 'Shore-In' on transfer switch (end that is wired to rv main power panel)
Then 'Main AC Power OUT' from transfer switch to rv main ac power panel




OR...just plug ac power cord into Gen Outlet whenever you are unplugged from Shore Power

It's simplicity itself.

You just need a small Square D box with wiring knockouts, a 120 Volt coil DPST continuous duty relay, a few wire clamps and wire nuts.

You wire the Hot and Neutral of the incoming 30 amp cable to the Normally Closed contacts. The Normally Open contacts are wired to the Hot and Neutral of the generator.

The Common contacts go to the RV. The relay power leads are wired to the Hot and Neutral of the generator, just like the NO contacts.

So what happens is if you plug into shore power, power goes through the NC contacts and your RV is hot. Now, if you want to run the Generator, just start it up, and when power is available, it automatically closes the Relay, and you have power.

Takes just a couple hours to install it all and configure and wire it up. Let me know if you need a schematic.

Better make that a "DPDT" relay with contacts rated for a 30 amp or higher load. And make absolutely sure it's a "break before make" relay! Commercial automatic transfer switches often have arc suppression and/or a delay timer that allows the generator to get up to speed with a stable voltage before connecting a load to it.

Mine says do not plug in power cord into generator until after generator is running...........

I was wondering at the type of switch after searching for them after reading your post.
Yes, please post the schematic....
thanks

If leaving the cord plugged in to generator, just turn main breaker off before starting gen, then after gen comes up to speed turn main breaker on.

Just got invited to play a round of golf so heading out for that after a quick shower. So the schematic will have to be 4 hours late or more. Sorry.

I will NEVER HAVE TO PAY FOR OR WORRY ABOUT A BAD TRANSFER SWITCH.

If the power plug was plug n play, I would press a button and the power cord would unwind itself and miracle it's way to the power pedestal socket and not only plug itself in -- but check for correct polarity and tightness.

You could not PAY ME $500 to force me to rely on an INSTALLED FOR FREE automatic transfer switch.

But then that's me...
