Okay, Uncle! From all those responses you'd think I was giving away a free
night with Paris Hilton, a NOS 1939 Unisaur, 500 BF of the wood of your
choice, and any three of Steve Knight's planes... But I digress...
Thank you for all of your responses, even the homicidal ones... I *am* a
layman, and if my terminology was unclear, I apologise. What I had intended
to do, was to have a single run of 12/3 feed two 20a circuits, so that I
would only have to wrassle with one string of romex. I wanted to have two,
two plug units in a duplex box, each plug unit being on a separate circuit,
sharing a neutral and ground. Using ASCII, this is kinda what I was

But, I also want to have things protected by GFCI... So, I'll take the long
way and play it safe... I've taken the 12/3 back in exchange for 12/2 and
will have completely separate wire runs...
I am sure I'll have more questions. Who do you want next to go with an old

Let me know...
I wouldn't take that even if you gave it away. You just happened to pick
the oldest, most controversial, most disputed topic of the wreck -
electricity. It doesn't behave logically, is invisible, and everyone has to
have it. So we make up incantations and have fights about it.
Help me here; I don't understand how this is overdoing it... I like (at
least on paper) the idea of having two plug nits on separate circuits in the
same box for convenience - shop vac on one, big honkin' router on the other,
for example... Are you saying it would be better to have a string of
outlets on alternate circuits, say 4' apart??
I appreciate your input...
A split circuit duplex receptacle is a common configuration in kitchens. You
generally see them where one side is also switched for a dishwasher or
garbage disposal. Practically speaking, and despite what you say above, I am
not so sure why you would want to do this in your shop as separately wired
circuits are much easier to handle DIYwise, not to mention that you may find
required, and _easy_ ,GFCI protection, which appears to be one of your
requirements, to be more expensive than the extra wire for separate
However, and in lieu of all the advice (and condescending BS) floating
around here, and for some additional GFCI information, have a thorough read
of "ernies" discussion at the following:
Although I haven't gone over it with a fine tooth comb, it appears to be a
pretty good, and calm, take on subject and will hopefully clear up some of
