What you need to know about RV electrical cords

There are times when our RV’s built-in electrical cords will not stretch far enough to reach a power pedestal or other power source. And so we need an extension cord.

But not just any extension cord will do, although many RVers do not understand how important it is to use a proper cord and not one that’s inadequate to carry the power to run appliances, the heater, air conditioning or other devices. It’s not uncommon to see RVs hooked up at campgrounds using power cords purchased at Home Depot intended for home use, that are not capable of carrying a load of 30 or 50 amps.

In this short video Mark Polk of RV Education 101 covers the basics of extension cords, including how to read the code embedded on each one that explains how much power it can carry. If you do not fully understand RV extension cords, we highly recommend you watch this video. Don’t risk damaging your RV, or even hurting yourself, because you used an inadequate cord.

And, in case you need an extension cord, you will find a number of good ones at Amazon that are specifically designed for RVs.

    • Thanks for your note, Tony. If you ordered something from an ad for top hat on this page, that’s not one of our advertisers. It was most likely an AdSense ad which is auto-inserted by Google, and we don’t have any control over it. But thank you for the warning, in case anyone else sees that ad. But, then again, I’ve heard of mail sent Priority three weeks ago in the U.S. and still not reaching its destination, so that might have something to do with it. —Diane at

      • This is true, I ordered a tailgate accessory for my truck back in December coming out of upstate New York and it finally arrived 2 weeks ago. P.O. said anything coming out of the NE is very slow due to the postal workers not wanting to work as long as the government is paying them to stay home.
