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.


Show me code in any country which demands tied circuit breaker handles
for 120v circuits. I double dog dare you!


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.


We're talking 120v here, not 240, clare. With 240v, both phases are
going to the same box. Here, there are separate circuits and boxes
with a single phase going to each.
