Campground electrical problem
Hello to all my good people out there - first and foremost as summer comes to an end I can only hope that you all enjoyed it as much as we did. Many great miles and memories this year.
We just returned from our big trip this summer - 3 weeks on the road and 2000km of towing enjoyment with our rig. We camped at several different places, some Provincial and some private.
At our last private park stay I encountered a strange electrical issue in the campground's system that I wanted to share, both to help understand why it happened and to give warning to others.
We were hooked up to 30amp service, and resting voltage was normal (about 118-120V). As soon as I turned on the electric water heater, voltage dropped to about 111V. Turn the fridge on, 109V. This concerned me since I had never seen a drop like this on 30amp and my cut off is 108V.
I switched the heater and fridge over to LP and tried the air conditioner. Again, voltage dropped from 118 to 110 with just that singe draw. Thinking it was a bad power post, I pulled out a 30amp extension cord and tried it on the neighbouring site with the same issue.
This was obviously a problem within the park's grid and despite that, many other campers were running full bore with their electrical draw; likely in the low 100V area, effectively killing some of their AC components.
Has anyone else seen something like this? What would cause the voltage to tank so much with 30amp service?
