High-voltage damage to your RV
Please take this poll about high-voltage outlets at a campground or house...
Everyone,
There were a lot of interesting comments on yesterday’s poll about low-voltages at campgrounds. So let’s keep the party going and take a poll about high-voltage damages to your RV. And these high voltages not only occur at campgrounds, they can also happen at your bricks and sticks house when you pay an electrician to install an outlet for your RV.
Some of the causes…
There’s lot of ways that high-voltage damage can happen with both 30- and 50-amp RV outlets. Here’s a few off the top of my head.
Loose neutral on a campground or home 50-amp outlet
Plugging into a 14-50 outlet wired without a neutral for an EV charger
Using a welding outlet adapter to plug in your 50-amp RV
An electrician wiring a 30-amp outlet with 2-pole, 240-volts like an electric dryer
Campground electrician mis-understanding a 3-phase, high-leg Delta service panel and sending 208 volts to 30-amp campground pedestals
Power company setting transformer taps too high
Lightning hitting the ground or wires at your campground or house
Please take this poll and add your comments below
Let’s play safe out there… Mike
Hi Mike,
A few years ago, I plugged our Newmar Dutch star in to our 50 amp receptacle that I had installed at home. The Progressive Industries EMS wouldn't let it connect. The code was that the voltage was to high. I thought the EMS was faulty and removed it, sent it to PI and they checked it, saying it was okay. I reinstalled it, same problem. (Okay, I know I was really stupid not checking the house voltage) So, I THEN checked the house voltage and found it to be 135volts. I called the power company and to my surprise, the sent someone out pretty quickly. This was before noon. At 6pm they called me and said they had found the problem. Something wrong at a substation. All was fixed and the motorhome was once again plugged in and connected.
Hey Mike - your survey question (s) were a bit confusing.... In our travels we have certainly experienced both high and low voltage issues, but since we always connect using a PI EMS, we have never suffered DAMAGE to the RV due to these issues. ST
