Has anyone else has an issue with a lighting system likely grounding just enough to eat GFI outlets but not enough to ever trip the transformer? Luckily, the problem is at my own house. The main line has all soldered spices and is looped. The light connections are Kichler disc's and I'm sure that's likely the cause of the problem. I've had disc's fail by melting or corroding and quit working in the past. It seems like someone could build a better disc that has a gasket and is more rigid. I'd rather solder all the connections if it fit in peoples budget. I have offered solder over discs as an upgrade but nobody ever bites.
