What the heck is that switch for?

[Wolfpack Fan]

We own a 2005 National Dolphin 5320. In the rear most, drivers side compartment, there's a switch box, that's labeled, off-on. It's the size of a standard 110v outlet box, with a toggle switch on it. I haven't come across anything in the owners manuals that addresses it speciffically. I've heard that it has to do with hooking up to a 30 amp or 50 amp service, but I'm not sure.

Can any other National owner shed some light on this mystery switch?

If you have basement air and heat pump it is a switch that only lets one compressor run if you are hooked up to 30A service. I leave mine on 50A and have had no problem even if hooked to 30A. When its on the 30A side the air doesn't cool as good.

If this is the switch you are writing about, thank you very much for solving the mystery!

Our mh does have the basement air/ heat pump. So the on position is for 50 amp service? Off position for 30 amp? What about on the generator? It's 7kw Onan.

Thanks very much.

The gen should run everything just like 50 amp service. When I can only get 30 amp service and it gets too hot for first stage of the air conditioner then I leave the switch up for 50 amps and turn off other loads. Then I drop the thermostat setting 3 degrees and the second stage will kick in and cool us down.
I would not do this if it was neccessary to run the microwave or water heater or the fridge on electric.

Yes, "On" for 50A, "Off" for 30A. The "Off" position cuts out the 2nd compressor on the basement system.

It's been my experience that the system is really lame running on 30A, unless the temps are moderate. I just don't stay at parks that have 30A power.
