Interesting...thanks.

There's nothing to add, really. The previous posters have said [almost] all!
One small (perhaps humorous) observation: some people learn by trial and error. Others from a book or an instructor. When dealing with a few things in life, it's better to go with the latter!!!

p.s.: The home improvement Mega-Stores carry excellent books for the do-it-yourself person. Even though one does not learn the trade by reading the book/s. But following their step-by-step advice keeps you on the right track and safe!!!

It seems kind of stupid to install a switched recep that is on two differeny circuits. I've never done it/seen iit.


Did two breakers trip (or one two pole breaker)?

If only one breaker tripped, the issue is somewhere else.

Not necessarily. If one single pole breaker tripped fast enough it may have been fast enough that the other didn't.

Why does it seem stupid?

I recently finished a complete kitchen remodel, and I wired up my dishwasher and garbage disposal this way. I wanted them each on their own circuit, and wanted both to be plugged into the same receptacle under the sink. The disposer had to be switched though. So I ran 12/3 from the main panel to the switch and then to a split receptacle. The hot wire for the dishwasher bypasses the switch. There is one double pole 20A breaker for the two circuits. Anything particularly wrong with this setup?

...If it was part of a multiwire circuit (shared NEUTRAL), there should have been a 2-pole breaker protecting the circuit, or they (breakers) should have been latched!

p.s.: There IS a difference between the former and the latter

Maybe it was?

We'll likely never know. The OP made only the one post and never returned with more info. Typical unfortunately.
This was also seven months ago.

At ~10kV per centimeter of spacing, at voltages this high I'd think the wire insulation would fail first.
