Low Voltage at CG - Thanks for help in being prepared

This post is to thank many of you who share your experiences here. I lurked a lot in March and April as we were getting going with our first TT and made some gear purchases just because of the advice I’ve read.

This weekend we stayed at a campground near the North Rim of The Grand Canyon. This particular one is the only location with full hook-ups in the area. We also selected it so we’d save some drive-time from home.

Bottom line is the site only provided 101-110 volts of power, averaging 107 volts. I knew about the problem right away because I test polarity and voltage at the pedestal before connecting my TT (it read 102 volts). By the time the CG manager stopped by to test with his VOM, we were getting 110, which he said is their typical max. Sadly, every 2-3 hours the voltage would drop enough to trip our surge protector (we knew because it would reset the clock on the microwave).

I ended up running our water heater on propane whenever we needed hot water, and I’m thankful the weather was mild and we didn’t need the A/C.

We enjoyed the forest setting, and our visit to the North Rim. And thanks to being prepared, I was able to identify the issue and work around it.

Best regards,
Chris
  • Hey, awesome! Glad you avoided any potential damage. And most of all. Welcome to the funny farm! I lurked for probably better than a year myself before I joined up. Glad to see new folks myself. It's good for us all. :)

    In addition to checking for low voltage, it is good to be able to "fix" it for your rig. I carry a Frank's Autoformer. Others carry a Hughes autoformer. The Franks one detects out-of-limit voltages and takes three types of boosting depending upon what you need.


    I use the voltage booster from Frank's Electronics as well. It provides a 2-stage voltage boost should you need it. The Hughes does not, I believe. Pricey...but you need it sometimes, as this guy did.
  • Alfred,
    I've started looking into autoformers, but will hold off until I see how often we have problems (or have a longer trip planned).

    One of the other tools already in my kit is a 50-amp to 15-amp dogbone. I've booked some 50-amp sites so we'd have that option. This particular CG only offers 30-amp.

    Best regards,
    Chris

  • DW and I camped at Morrow Mountain State Park in November. I noticed that our ceramic heater was not running as strong as usual, so I checked the voltage....99 volts. We had to manage our power usage, turning off the heater to turn on the water heater (propane part wasn't working at that time). We didn't use the microwave, and it was good we didn't need a/c.

    I've since learned to check voltage at each CG.
  • Besides making sure the post won't electrocute me, the first thing we check is the voltage when hooking up. Glad you got it figured out.
  • Glad you were aware of the dangers of low voltage. Nice that you didn't need the A/C. I would imagine that you were one a few that knew there was a problem and took steps to correct it. Good job!
    This forum has a ton of valuable info on it and has saved me time, money and frustration on numerous occasions.
    Good that you are no longer a lurker...Welcome!
