Look for Ray Mullen's book on Residential Wiring. It includes a PDF file of the NEC.
I have the 1999 edition. I am not sure that the 2002 version is available.
Bill can check his shelf, or order one from Delmar.
If you are a member of the NFPA you can download the 1993, 1996, and 1999 NEC in PDF format and access the 2002 NEC on line.
