That's a great idea. I'll check Home Depot tomorrow to see what they have. Right now I have both legs running into the same GFCI outlet. Hopefully by splitting them up the problem will be solved......temporarily.
Is there any easy way to determine which elements are contributing the most to the GFCI problem? Every time it rains here it trips my GFCIs. I tried to go out and and systematically figure out which ones caused the problem, but it seemed random (sound like the incremental load problem described above) My display consists of string lights only. I don't have any wireframes, but I do have some strings along my bushes in the front, near the ground.
