It has been a while since I have had my head in a code book and I am preparing to wire my new home. I was wondering how the rules are now days concerning placing a panel in a closet? Also I had an electrical friend of mine tell me that I could run a 12/3 wg and split two circuits sharing the neutral...IF they were on the same phase...My recollections are that you can't share the same neutral unless you are on different phases? What is the correct procedure for this circuit? Thanks in advance.

Re: Sub Panel in Closet?
Strictly speaking the closet thing is open to interpretation by the AHJ. If the contents are considered combustibles the panel can't be there. A workaround may be to divide the closet and provide a clear section for the panel. Check with your AHJ. Look at 240.24(D)(E) about closets & bathroom panels. The rest of your question is answered by Article 110 and the way your AHJ interprets it. There is a lot of important stuff in 110 about how your subpanel needs to be.
Multi-Wire branch circuits must be on separate phases. They are also called Edison Circuits if the circuits land on one yoke or strap. Look at Article 100 for details. Also, look at 210.4(A), 210.4(B), 210.7(C), 240.20(B)(2), and 300-13(B) in the 2002 NEC for more details. Also, check with your AHJ to see if multi-wire circuits must originate from adjacent breakers, or if they require a handle-tie. If they land on one yoke or strap they do need a handle-tie-- the rest is up to the AHJ.
If you post back with more detail we can provide you with a less generic, and a better & safer answer.
How far does your experience go back? What is your experience?

Re: Sub Panel in Closet?
Your first question about panelboards in closets, I believe that 240-24d '99 would tell you "no", if it is a "clothes closet" that you are refering to.
2nd, yes, your multiwire branch circuits must be on opposite phases in order to eliminate overloading of the neutral. Also if your multiwire branch circuit terminates on the same yoke or strap, you must use a 2 pole breaker to open your circuits simultaneously.
