SEASONAL QUES: Wrap outdoor Xmas Lite Junctions?


Never saw any info on this, but I'm of two minds. In the past I have wrapped the plug/socket sets on Xmas lights, but also seem to remember just finding trapped moisture underneath when taking them down (a year ago is a long time for my memory to assist me a lot).

Any conventional wisdom on this...wrap or no?

It's a toss up for sure. If your sets are 120vac wrapping them up in a plastic bag won't hurt as melting snow can cause a short and blow fuses or pop breakers or damage light sets or all of the above. If you are off grid and are running 12vdc or 24vdc, bagging your connections with a small opening for air will allow the connectors to last much longer before they have to be taken apart to reburnish the contacts. If all the connections are under eves or protected from direct snow and rain contact there is practically no need to protect them as plugging them in and unplugging them burnishes the contacts for a good connection. Good Luck and Merry Christmas

I used to wrap the connections, and then found moisture in them when taking the lights down. I quit wrapping the connections a few years ago and have not had any problems. My displays are fed from synchronized timers plugged into outdoor GFCIs with in-use covers and everything works just fine.

When the kids were younger and at home I also used to put up very large displays. I always wrapped each connection with electrical tape to prevent moisture, particularly rain, from entering the connection. But like others I would find the inside of this wrapped connection having moisture. Then I started putting wooden stakes in the ground for those very low ones and sort of 'hanging" them off the stake to keep them off of the ground. I also started using the power strips with built-in GFCI's.

Some form of GFCI for outdoor electrical usage is a good idea (required around here on new builds) just so there is no chance of you dancing "The Electrical Jig".
