World's best 1996 NEC handbook! Only one Codebook reveals not only what the Code says, what it means-McGraw-Hill's National Electrical Code Handbook, 22nd Edition. We don't stuff our book with a reproduction of the Code-instead you get 100% explanation and interpretation of new and difficult Code rules. What's more, it all comes from Joseph and Brian McPartland, the two leading Code experts in the country. And, as new clarifications develop, you'll stay up-to-date with annual NEC supplements, autoshipped to you for free, no-obligation 30-day examinations-an exclusive service offered only by McGraw-Hill! Pass inspections the first time, with the Codebook contractors have turned to first for over 60 years.
