Your GFCI and AFCI trip checklist in real life

[Alan]

Quick troubleshooting thread for the Electricians Forum

GFCI and AFCI trips can be super straightforward or they can turn into a long day depending on what’s causing it

What’s your real world checklist when a breaker or receptacle keeps tripping and the customer says it happens “sometimes”?

And when do you start thinking neutral problem versus an actual load issue?
Any telltale signs that point you one direction fast?

Share whatever steps you’d tell a newer electrician to follow so they don’t just swap parts and hope it goes away

First thing I do is hunt for patterns. Does it trip on rain days, after vacuuming, when a fridge compressor kicks, or only when someone uses one specific outlet? “Sometimes” usually means either moisture/garage/outdoor stuff, or one sketchy appliance the homeowner doesn’t connect to the trip.
