Back to the Future!
I just discovered that Part 1 of my article series on the ABCs of campground power and grounding was never published on RVelectricity.com, only on RVtravel.com. So to keep everything consistent I’m reprinting Part 1 of it below. Part 2 was published in last month’s RVelectricity #14, so now you have both articles in the same newsletter series. If you think you’re confused, realize how confusing it must be for me. So it’s Back to the Future….
RV Electricity – The ABCs of campground power and grounding – Part 1
AC power and grounding from the electric pole to your RV
I recently realized after trying to explain to an electrician the facts of how electricity gets from the electric pole into your RV outlets, that there were no basic diagrams to be found. So I’ve started making drawings of the entire layout, which I’ll publish here. While this looks complicated at first glance, it’s really pretty straightforward. Part 1 will cover how it’s all hooked up according to the National Electrical Code, which also shows how the neutral and ground wires are bonded (connected) together in the power company incoming service panel, but nowhere else. And Part 2 from last month’s RV Electricity newsletter covered all the various load and fault current paths, including how to integrate a generator with a floating neutral into your RV’s electrical system.
On another matter: I’ve agreed to begin direct consulting with RV Travel readers on your RV electrical issues. Chuck Woodbury will set up a consulting page where you can hire me on an hourly basis for the price of an RV technician to help troubleshoot the electrical problems your RV technician can’t repair. I’ve been electrical troubleshooting for well over 50 years, so I’m sure I can help you when others can’t. More on this soon.

Q&A’s from other forums
I spend a lot of time on dozens of other RV forums answering questions about electricity. Here is one really interesting topic that’s getting a lot of attention: Just how do you ground a sub-panel?
From the Montana Owners Club:

Last month’s survey results:
OK, so I forgot to put in a category for solar power, but otherwise the results of this survey are very interesting.
Nearly half (46%) of those responding to the survey have a dedicated 30- or 50-amp RV pedestal installed near their RV parking spot. I think that’s great, since that will allow you to use your RV as an extended guest room for when extra relatives or friends show up for the party. And as long as this isn’t a motorhome, it’s a great place to put up your friends for the night who might have consumed a little too much adult refreshments at your party. You can give them the keys to their own private lodge in your backyard, and send them home in the morning. It’s the responsible thing to do.
But the other 46% of you power your RVs from an extension cord plugged into a 15- or 20-amp outlet on the side of your house or run out the window. This is less than ideal since in many instances these may be lightweight extension cords that can easily overheat if you draw too much amperage in the RV. The orange 50′ or 100′ cords really are the last thing you want to use to power your RV.
Plus, remember to always confirm that the power outlet you’re plugging into has a solid ground connection, and check the skin of your RV for a hot-skin/stray-voltage any time you plug in. I’ve had a few cheap extension cord failures where the ground pin broke off inside of the molded plug and even though it looked like it was fine, in reality there was no ground connection. That’s a recipe for a shock or electrocution. ALWAYS check for proper grounding and no stray voltage.
Some of you don’t bother to power your RV while parked, and that’s OK as long as you pull the battery(s) and put them on a float charger in your garage. Letting your RV’s house batteries go flat over the winter will surely reduce their lifespan, and I don’t have to tell you that RV batteries are expensive.
Tools and Other Devices
Admittedly, I didn’t think much of the Handi-Cut when my dad gave me one for Christmas a few years ago. It languished in my tool bag forever, never even being tried by me. But last year my general contractor friend Karl was helping me install some narrow molding in the house and he pulled out his own Handi-Cut. What?!
This thing actually works great for cutting small wood, plastic and rubber pieces that would normally be destroyed with a saber saw or flattened with a pair of diagonal wire cutters. You just have to be careful not to twist sideways when cutting or you’ll break a chunk out of the hardened steel blade. But even if you do, not to worry since you’ll find a few replacement blades in the handle. This is now one of the tag-along tools in my road kit since I never know when I’m going to need to cut or trim something during an install or repair. Learn more or order at Amazon.

Technical training from Sears (of all places)
I never expected to find anything related to electrical training at Sears, but they’re offering three short videos on how to read and understand electrical schematics, which are really quite good. While they primarily focus on appliances (such as your residential refrigerator), the general principles apply to all schematic reading and understanding.

OK, I’m rapidly approaching the age when I can completely retire if I like, and many of my friends and family are urging me to take retirement and simply travel. My twin brother just retired last year, and my younger sister just retired a month ago. My dad retired some 30 years ago and still seems perfectly happy to live in the woods sawing down trees with his variety of chain saws. Read more.
