Stay in the lead with electrical answers and support in the 2011 National Electrical Code® Handbookfrom NFPA®, the NEC® source.

The NEC has changed and staying up-to-code is essential! Make sure you’re informed with the single most valuable tool for NEC users — the 2011 NEC Handbook from NFPA. This is your hands-on source for the practical solutions and Code rationale you need to comply with the new NEC, avoid violations, and answerCode questions on the job. The 2011 NEC Handbook is loaded with one-of-a-kind features!

Full 2011 NEC text — no other electrical reference has it!
Expert commentary with coverage of changes in the 2011 NEC’s requirements, including new rules focused on workplace safety
First-time commentary on new articles, such as an overview of recommendations for applying Article 840’s rules for premises-powered broadband communications systems
500+ full-color photos and illustrations such as schematics, floor plans, and cross-sectional graphics not in the Code
Extracted data from NFPA codes and UL to deliver a wealth of electrical safety knowledge
For the first time, vertical rules alert you to Code additions, and bullets signal deletions — exactly like in the NEC.
Commentary is shaded in blue so it’s easily distinguished from mandatory provisions.
