Where Can I get a complete reading of Article 312.8 of National Electrical Code 2008?
In the NEC of course. :p

There are usually copies in the library, and also in stores like B&N.

Or you can try the link above. You do have to sign up (for free) but you can view the whole NEC.

Or I can do this:

312.8 Enclosures for Switches or Overcurrent Devices.
Enclosures for switches or overcurrent devices shall not be used as junction boxes, auxiliary gutters, or raceways for conductors feeding through or tapping off to other switches or overcurrent devices, unless adequate space for this purpose is provided. The conductors shall not fill the wiring space at any cross section to more than 40 percent of the cross-sectional area of the space, and the conductors, splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space.

Stan,

Do you have the NEC on Disc in PDF format? If so where did you get it, NFPA?

I have back to 1999 in .pdf that come with the NEC CD.
I also have them in stand alone .pdf files. I'll try and remember where I got them for you.
