GFCI + Snow = Problem
So I thought I would be extra-safe this year, and plugged my outdoor Xmas
lights into some GFCI-protected outlets. All was well until the snow came (6") and now somewhere in the system (I've probably got 30 different extension cords out there) is a leak that the GFCI is "protecting" me against. I can certainly see how snow could potentially produce enough conductivity to generate the small amount of ground current that GFCI's are designed to sense. I am planning (by next Xmas) to run some underground conduit and have some outlets "popping up" at various places in the yard, so I don't have to be running extension cords quite so far. My question is, should I _not_ use GFCI outlets in the yard? Will I encounter this problem every time there is snow? Should I make sure to _not_ use grounded cords for this? I mean, none of the Xmas lights have ground connections, so they only thing the ground connection is doing, is providing a means for the GFCI to complain? Thanks! Chris |

Just be carefull with the plug-recepticle connections, don't let them lie on the ground. You can wrap the Plug-Recepticles with plastic food wrap and tape that up, or buy a comercialy avail product that keeps the connection dry. Should I make sure to _not_ use grounded cords for this? I mean, none of the Xmas lights have ground connections, so they only thing the ground connection is doing, is providing a means for the GFCI to complain? That won't help. The current will return through the earth! Thanks! Chris |

GFCI + Snow = Problem
You are much safer to use grounded extension cords. This is the best,
even though your lights themselves do not use the true ground from the outlit. I would suggest to clean off all the cords, so that they are dry. This means unstringing them and bringing them in to clean and dry out. After they are dry, you can put them back together. Wrap the joints with several layers of plastic bags, like the ones that you get with your shopping order. On the edges, wrap a few turns of electrical tape to seal them, so moisture cannot get in where the joints are. This way of insulating the connecton points, will prevent water from getting in. You should not have any ground fault problems this way. Jerry Greenberg http://www.zoom-one.com -- "Chris Cooper" wrote in message ...

The GFCI detects a diversion in current from hot -- neutral to hot -- ground. The ground lead is superficial past the GFCI for the purposes of tripping it. |
