Extension Cord Question

I've learned on these forums that you don't want to use too small an extension cord to plug into something that requires a heavy load, such as electric heater, your RV, etc. My question is can you use a heavy duty cord on items that do not require one? Specifically, we're putting up Christmas lights and I'm wondering if I can use the heavy duty cord I use to plug the RV into the house (via the adapter) to run low voltage lights? Will it cause damage? Thanks.
  • A heavy duty cord doesn’t necessarily mean it’s capable of a heavy duty load.
    I just found at Home Depot a “Heavy Duty” cord that used #14 wire. Good for 15 amps.
    Not a heavy duty load in my opinion.
  • “DW likes to vacuum” Me too. A clean TT is a happier place.

    Thanks.

    No it won't cause any damage.

    Just a FYI about using/protecting your RV extension cord while out in the elements for the duration of holiday season. And if you are using an extension to power your RV also! :C

    You need to cover the connection to protect it from the elements. And raise it off the ground. Just google "waterproof" extension cord covers there are a ton of them to choose from.

    And in my experience the most important part is to take a look at the prongs of the RV cord. If they are black and not shiny gold take a file and grind/sand it down till you can see the original gold color.

    If you don't keep these prongs clean and allow them to turn black they arc and will melt your extension plug as well as the RV cord plug.

    Even with a waterproof extension cord cover in place I still place the covered connection on top of a big concrete brick when ever I use an extension cord to the RV.


    Not a bad idea at home.

    With my little TT I wrap a old plastic grocery bag lightly around the cord ends when using a RV extension cord at the park. Keeps the rain out.
