I'm not sure what this means, but if you're running two 120v circuits
using 12-3 from a pair of 20A breakers, make sure the breaker handles
are tied together such that both trip if either one trips.

Because???


Because 1) - it is code.
2) if one circuit trips and you assume the wire is "dead" you
could be - the black could be dead, and the red live, and a lifted
neutral (which is common to both) would be LIVE.


Why not use a 240V breaker, with 12/3, then there is no issue with
tying the handles, you still get two 120V circuits. Sounds safer to
me, but not sure about code.


That's normally what is done.

That is what I thought, split kitchen receptacles like that are common
(read code) in Canada, but I thought there was an issue with them in the
States, so I wasn't sure in this situation.
