I pulled the gfi at my house, but I dont dare do it on a clients home.I have found that a GFCi that is at 90% is much more likley to trip than one at say 50% the extra load is already super sensetive.
Another thought older home with out GFCI's do just fine without them.
We have cut our gfi calls significantly this year, instead of the usual dozen or so calls, we have it down to 3 or 4 and of those 2 have had the issues found and corrected.
We split the load, even with LED's, to lessen the chance of tripping in the rain and also have come up with a few tricks that seem to have worked extremely well!!!
