I would go to the city desk at Viking Electric and ask the guys there, they can usually give you recommendations on meeting code requirements. They also have some pretty schweet products. For example, they have bundled cable that contains 1 coax, 2 CAT5, and 2 fiber optic. That stuff is heaven sent when you're pulling wire through tight spaces, and it's nice to know that you're set for fiber if that ever becomes the next wiring standard. Good luck! EM
