Hot Temps causing electrical challenges

The current run of 100 temps in the daytime are challenging a lot of campground power supplies. We are in New England at the moment. When I plugged into the CG 50 amp, my internal meter showed 106 volts. I could not get either A/C to come on. I unplugged from the CG supply and cranked up my generator. Everything worked fine then. The campground owner measured 108 volts at the pedestal and all the other 50 amp sites. He had complained to the power company who cited "demand". We ran the generator until we went to bed and then went back on shore power leaving the A/Cs off overnight. This morning, the meter shows 112 volts. This campground is out in the country and I expect everyone is pulling a lot of juice trying to stay cool. I'm interested in what others with 50 amp motorhomes are finding.

We have had similar CG volts. Here in ill , we have a steady 120. Our Progressive Ind EMS has shut us down at 104 volts five times in the last few weeks ( really saved our bacon ). Your equip should work at 108 ( not the best for them , but should work )

You should look at your a/c manual and see what the voltage tolerance is. It's usually +- 10%, so 108V is at the borderline. It's good info to know. Also, some sites with long cables runs have a greater voltage drop, hence lower voltage. Sometimes you may just have a bad site location, but at this time it looks like the utility is having difficulty regulating power. Stay cool!!

We are in an RV park with the same issue. Although our motor home is a 30 amp unit we can run both ACs at the same time because we have a load shedding energy management system. I was measuring 106 to 108 volts and the AC current used was increasing more than I liked so I switched to a 50 amp to 30 amp adapter hoping the larger wire gauge on the 50 amp leg would have a lower voltage drop. That worked okay for a while but as it got hotter here in CO the voltage began to drop and I had to turn the rear AC off and shut the bedroom door. That allowed us to cool the front. The good news is that in the last couple of weeks the voltage has gone up and stays over 108 all the time now so we can run both ACs. Maybe the power company made allowances for the increased load somehow. We have had record setting over 100 degrees temps for over 1 1/2 months now and although we are full timers and usually just go north when we get too hot that isn't an option right now because of DWs moms health.
