Can Anyone tell me what this switch is for?  I have never been able to notice any difference in either position

    That changes the volt meter to the left of the switch. It should also have a center off.

    I'm not following you.  I am a novice when it comes to electrical stuff.  How does it change the volt meter?

    what Raybo is saying is if the switch is on main, it will read the main shore voltage on the meter.  If it is on air conditioner, it will read the voltage being supplied to the A/C.

    Handy if you use 2 shore power connections or to watch for low voltage if you have a long / undersized cord.

     312, that sure is true.  I learn something each time I log on here (which the admiral tells me is a lot :D  )

    RY, it reads the house batteries.  I use mine to gauge when I need to start up my genny.  I did compare it with a DVM right on the battery.  Mine at the panel is about 0.3V lower than what is actually at the battery.
