I'm currently set up on private property in the foothills of Mt. Lemmon just north of Tucson. I have 30 amp power from a nearby garage (about 50 feet away). Since mine is a 50 amp coach, I have a 30' 50 amp cable connected directly to the RV and a 25' 30 amp extension plugged into the garage outlet. A small voltage meter I have plugged into a 115V galley receptacle in the coach reads a steady 117–118 volts with only the refrigerator, interior lights and battery charger running. When I add a space heater the readout drops to 113 and when the coffee maker (or microwave) are added the voltage gets down to 109–110. This worries me a bit — at what point do I start turning things off? I have read that below 110 volts some appliances may not operate properly, that damage may even occur. Does that mean I'm okay at 110?
