RV Electricity – Troubleshooting 101: Over-current testing

Mike, I have a question but, as I said at the RVillage Rally, it’s a little long. What would cause a pair of 2kW generators to overload when charging my batteries? Looking for your guidance in what actions I need to do to either the generators or the trailer to allow me to charge my batteries with the generators.   ... Read More

Surge Protectors and Joules and MOVs, oh my!

Dear Mike, After reading all your articles about voltage problems, I’m now in the market for a surge protector but a little confused by all these Joule numbers. Some are rated at 1,400 Joules of protection, while others are 2,100 or even 4,200 Joules. So first of all, how do you pronounce Joules, and just what are they? If these... Read More

RV’s power outlets are melting. Help!

Dear Mike, I noticed the outlet for our microwave in the motorhome had started to melt. Upon removal of the outlet I saw that the wires connections were not screws but pressed into a pronged connection. I replaced the outlet with a standard screw-type outlet. I checked other outlets and discovered the one to the washing machine also was burned... Read More

Do I need an “intelligent” surge protector for 50-amp shore power?

Dear Mike, Thanks for your recent articles on why an intelligent surge protector is needed for 30A service. But would this also apply to 50A service? I have been reading these articles and did the survey, but then realized everything you wrote has been about 30A plugs and service. —John G. Dear John, While it does seem like all I’m... Read More

Why you need an intelligent surge protector

I’ve written a number of articles here about surge protectors and the difference between intelligent and basic models. The overview is that basic surge protectors usually cost less than $100 and offer protection from nearby lightning strikes and voltage spikes on the incoming power line. However, they can’t protect your RV from an over-voltage condition that occurs if you happen... Read More

RV Electricity – Ground rod testing Part 1

Mike, Is it possible to use normal measurement tools such as a multi-meter, surge protector, or Klein dual voltage no-contact tester, to simply measure the effectiveness of a “ground rod”? I know that not all soil conditions will ground the same. I try to be very thorough prior to connecting to shore power to prevent damage to my motorhome electronics.... Read More
