So, the outcome is the same. If you are using 12amps, you are using 12amps, regardless of whether the inverter is ON or OFF, when plugged into shore power.

I think that is the test I wanted to see when I get my coach back. I have NEVER consciously turned on Inverter when I had any kind of shore power. I do have Magnum Inverter CSW 1012, but I assume it is the basic 1000 watt variety; so I am sure it does nothing special.

I think your point may save me from a test because if I follow; you are saying for the few in house electrical receptacles that are also connected to inverter, they ALWAYS consume off the shore power if it is available? Therefore on/off switch to inverter has no effect while shore power is on. Coincidentally the batteries would be getting a slow trickle charged even though the inverter is not being used.

Now that I hopefully got that right, can I throw another twist Assuming all of the above is true, but I am just determined to not trip that 15/20 amp breaker. So given what I just learned, I go outside and and plug two extension cords to the 110 VAC output on my Magnum. I then plug my outdoor refrigerator and TVs to the extension cords. Will I then be drawing current from my batteries, and NOT the shore power thus reducing load on the 15/20 amp receptacle..., and all the while the shorepower would be charging my house batteries?
