Finally figured out how to get those stubborn GFCI breakers to stop tripping on a job site in Portland

I had this problem for weeks where a new GFCI breaker would trip every time it rained. Kept swapping breakers and checking wires. Then an old foreman told me to check the neutral bar for paint overspray from the builders. Sure enough, there was a speck of paint causing a bad connection. Cleaned it off with a wire brush and it's been solid through two storms now. Has anyone else run into paint or debris messing up their neutral connections on new builds?

Check the torque on your neutral lug while you're at it.

The first time I had that issue I spent like three days chasing a phantom short before my partner walked over and just looked at the neutral bar for like two seconds. I mean, I felt about as smart as a bag of hammers after that.
