Circuit breaker tripping

[Hall]

I believe the code calls for AFCI or GFCI breakers on almost all circuits on newer homes.

Our home is ~20 years old and AFCI breakers are only on the bedroom circuits.

In our son's house, he said there's 1-2 AFCI breakers (suggesting the electrical was redone semi-recently and presumably inspected) but the circuit in question is NOT on an AFCI breaker.

I suggest trying individual different burners. It is likely there are 2ea burners on one, 120V leg. And 2ea on the other.

And of course, the voltage check per leg, during the problem.

A bad neutral could drop voltage to the Keurig increasing the amps till the breaker blows.

Or it is just a weak breaker that trips when there is an uneven load.

If you want to drop 25 bucks on a nice little device, Klein has one of those palm sized digital outlet testers. Checks voltage, open neutrals, grounds, GFI trip time, etc. Plug it in to the kurieg outlet and run a few different scenarios. Might not show anything but you might get lucky and justify picking up a new little toy.

Son has the non-digital type and it's wired properly

Rats. At least we know what it isn't. Proceed with process of elimination.

Replace the breaker. They go bad.
