Title: Low AC voltage

I am in a campground and my AC electricity keeps going off with the warning "low AC voltage". This seems to be happening primarily in the evening - when everyone is in their rig using electricity.
I have a plug-in voltage reader that plugs into AC outlets in the motorhome and it reads 105 to 109 volts just before the AC cuts out - particularly if I have air conditioner on. When I am on the inverter it always reads 118 to 121 volts.
During the daytime everything was working fine and the voltage was reading about 113 to 116. I can understand the electricity cutting off to protect appliances from low voltage damage, but how can I adjust this? And why are other coaches around me not having the same problem?

Load on the the branch circuit feeding your line of RV pedestals goes up so voltage goes down, larger the amp draw lower the voltage. Undersized condutors, bad terminations, many possibilities.
Possible there is a weak spot in pedestal you are plugging into or the whole line has voltage drop and your fellow campers rigs are not as sensitive (smart) as yours. Check voltage drop at neighbors, if ok have management check your pedestal breaker etc....

None of us can help you without at least knowing what coach you have. A name would be nice also.

What campgrounds' electrical are you having problems with? Did you consider a post on RV Parks Reviews?

You may be the last pole on the line ran, nature of the beast may have to power share by shutting down some loads.
