Lately, one circuit on my box blows. It covers the microwave and

understand it blowing when another heat-using appliance, like toaster
oven or toaster runs at same time as microwave. But now it's blowing
all on its own.

Last time, today, only the micro was being used, to "reduce" a glass
dish of chicken drippings.

Can one circuit go bad all on its own? If so, why? And what should I
do about it.

Any info appreciated.


Since nobody has mentioned this yet and it sounds like it's a kitchen
circuit, is the breaker perchance a GFI one?

The microwave may have marginal "hot to ground" leakage which sometimes
becomes high enough to trip a GFI breaker.

If it's not a GFI breaker, then I'll side with those who say, "change
the breaker.
