I'm not an electrical contractor, but I'm a pretty experienced DIYer having done a lot of residential wiring on my own homes - under permit. I'm stumped on a current problem, so I'd appreciate any troubleshooting tips.
My home has 200 amp service. From the main service panel, I have run a 50 amp sub-panel to the other end of my basement.
The bathrooms and exterior outlets run from a GFCI breaker in the main service panel.
From the sub-panel, I have a 15 amp dedicated circuit supplying the microwave in the kitchen.
The subpanel was installed about 5 years ago - and inspected. All has been well until a few days ago.
Now, when one turns on the microwave (a dedicated circuit from the sub-panel), the GFCI breaker (in the main panel) supplying the bathrooms and exterior outlets flips off.
Any explanations or ideas?

Since all was operating correctly untill recently, try replacing the GFI breaker. After all, they are electronic devices & cannot handle surges & electrical storms any better that your computer can. Maybe you had a recent thunderstorm, maybe not. Entropy gaurantees that everything will crap out sooner or later.
Few things are harder to put up with than the annoyance of a good example.
I'd hate to tell you to replace the GFCI breaker without being sure. But once you've eliminated everything else, that has to be it. If you replace it and that wasn't the problem, you can install the old GFCI breaker on another circuit to protect that circuit too - so don't think of it as money wasted.
