Upon closer examination… it is possible that the two branch circuits were separate. I say “possible” because as the two breakers were tied together, it was not possibly to trip one without tripping the other. Hmm… :-k
Being willing to look the fool as opposed to having the gal go through grief, I called it like this:
2.7 No microwave present at this time, however the breaker for the refrigerator circuit is inter-connected with the breaker for the microwave circuit. Current electrical code (26 - 720 a & d) states that a refrigerator can only share a branch circuit with a recessed clock, and that a microwave circuit shall not share a branch circuit with any thing else… and while the two “circuits” may be separate, as the breakers are inter-connected, you can not help but trip both should one or the other overload.
To be on the safe side, and as there are still contractors on site, I recommend further evaluation by a licensed Electrical contractor to ensure that this arrangement is acceptable.
Thoughts and critique always welcome!
As the project isn’t completely finished yet, there are still guys with hard hats still on site - so she shouldn’t be out of pocket for getting one of them to check this out. If she is, I’ll cover the cost and consider it a lesson learned.
