I have 6 outlets outside my house that I use for flood lights to light up the trees and front of the house at night. They've worked fun since they were installed, over a year ago. They are all on the same circuit, ran off a time clock inside the house. Every receptacle is a GFI. The past few weeks, I have been having one GFI trip and sometimes the two downstream from it would trip also. I would reset them and a few minutes later, it would trip again. The one that kept tripping the most was replaced with a new one, figuring that maybe it was bad. The problem still happened, so I replaced all the spot light sockets, because some had collected water in them and the insides were turning green. It's been wet here the past few weeks and I am still having the problem. At this point I am stumped and don't know what to do next. The only thing that I was going to try was to keep the one GFI that feeds off of the timeclock and install regular receptacles in place of the downstream GFI's, but I'm not sure if this will solve the problem. Perhaps all the rain has dampened the GFI's and they just need to dry out? Any comments are appreciated. Thanks

ok, 1 more question: we currently have overhead service from the pole, but before I redo the driveway, I thought I'd bury some conduit so that when we're ready to run wires underground, there would be no need to dig up the driveway (ok, there's always a need to dig up the driveway) so, can you put down the pipe now? and if so, is there a recommended way to seal off the ends to keep out critters, etc. thanks again! vd.
