Speaking of GFI tripping. I just install a lot of Christmas lights and it seems that 2 of my many GFI receptacles trip. OK, now I know that I can replace them. However once I turn on the lights and see these 2 strings aren't working. I go out unplug lights, reset GFI and plug lights back in. They will work all night long. Next night I turn on all outside recpt. and the same 2 strings (which are on different recpt. and different sides of yards.)do not go on. I rest GFI and they work all night long again.

My question, these are "newer" style GFI that have to have power on to rest. I still have the old style where you can reset without power. Could a rush of current when the lights go on be tripping the GFI? I am more curious than anything else.
