I'm back... Now it's a wiring question. I'd like to run a string of
outlets
at benchtop height, and run two circuits. I'll put a pair of outlets in
each box, 1 on each circuit. Can I safely run 12/3 for a pair of 20 amp
circuits using a common neutral (white) and ground? I'd run the red
wire
(marked black) to one outlet and the black to the other. The two
outlets
would share the white wire, along with the grounds.

At the panel, I'd have the red (marked black) wire going to one CB and
the
black one to a separate CB. If I can do this, I'd have to string way
less
NM... Would this be a violation of code? Is this safe?

I know, I know... call an electrician or an EE... I'm just trying to
get
a
little help here....

What you are looking at is a "split circuit" receptacle. It's been
perfectly
legal in a number of locale's, but I am not sure what the latest NEC says
about it.

Two caveats that are generally required to do it:

1. You must cut or remove the metal bridge on the duplex receptacles

2. It is generally required that you must use two, two pole circuit
brkr's,
with the two circuit brkr's "tied" together so that if one trips, they
both
trip.

In any event, the terminology you want to use with your building
inspection
department is "split circuit receptacle".


Look at it again Swingman - he doesn't want to split an outlet, he wants two
duplexes together in a double box that have their own hots, but share a
neutral and a ground.
