One duplex receptacle split to be controlled by 2 switches
 
Hi. Just wanted to ask if I could run 3 wire cable (black,red,white with ground) to a duplex receptacle (breaking the tab on the hot side) in order to switch the top half of a duplex receptacle with a 3 way switch and the bottom half with a single pole switch?

Yes, what you are proposing is acceptable by code.

Yes.
But in the diagram grounds not shown for ease of drawing

Thanks! That's exactly how I was thinking of wiring it. What do you mean by no neutral on the second 3-way switch or the code police will get you. Do you mean to make sure I mark it black so it is identified that I am using it as a hot wire?

2011 NEC requires that a neutral be at each switch, a requirement that your locality may or may not require.

Oh. Throws a kink in my plan then. Does that mean you can't back feed a switch anymore if power comes into the fixture instead of the switch box since there would be no neutral? Maybe I'm just not understanding this correctly.

Id just run a piece of 14/4 if you want to run it from existing outlet box before the switch, that way you have a neutral in the box.
Are you switching it from multiple locations?

So I will have to use a 4 wire cable (plus a grounding conductor) to be code compliant with the 3-way switches and just have some white neutrals with a cap on it hanging in the switch boxes? And if back feeding a single pole switch I will have to use a 3 wire cable (plus a grounding conductor) and have a white capped in the switch box? Correct?

That will work for the feed side of a pair single pole or 3 way
Switches.
If you were feeding the switch box first youd be able to run 14/3 to
Feed the outlet.:)

As sirsparksalot said, a neutral is required at switch locations now if your locale has adopted the new code.

If you never plan on putting a timer or motion sensor in the box then I won't tell that there is no neutral there. In my opinion not a big deal. But if you get some 14-4 cable just cap the neutral of in the box.

Thanks for all the help everyone.

Hi. One more question. I want to do this this with 4 duplex receptacles in the room. I plan to bring the 3 wire cables from these 4 receptacles to a large junction box and connect the all reds to the red switchleg and all the blacks to the black switchleg. Correct?

That's fine as long as he junction box remains accessible and you use the proper sized wire nuts for the connections. It might be easier and take less wire just daisychain the receptacles with 3 conductor wire.

One last question. I have a bit of a shallow wall to deal with for this and was wondering if there is any problem with putting in a 4 square box with two duplex receptacles and switch each duplex on separate switches(one with the red hot wire and one with the black hot wire) instead of splitting one duplex receptacle? I figure I waould just need to pigtail the neutrals together. I already have the required constant non-switched receptacles accounted for the walls in this area. These switched receptacles are for lamps and christmas/holiday lighting only.
