Construction Codebooks > National Electrical Code > 2011 NFPA 70 Softbound NEC Code Book (#11PB)

• Drawings can easily contain code violations. You need to check the drawings before doing the work. That protects your company and it protects you.
• When a question of "Can we do it this way?" arises, you'll be able to find the answer yourself.
• If a question arises about something you did, you can look up the Code requirement rather than taking someone else's word for it.

And that copy needs to be current. Why:

• The NEC is revised every three years. This is the Code cycle. Things change.
• You may miss a requirement, and thus commit a violation.
• You may do something in a more time-consuming or costly way than the NEC actually requires.

• New Article 694 has first-time requirements for small wind electric systems.
• Revised Article 625 includes updates on safe battery charging for plug-in hybrid vehicles that reduce the risk of explosion.
• Revised Article 705 covers interconnecting generators, windmills, and solar and fuel cells with other power supplies.
• New Article 840 addresses the increased demand for broadband communications systems with requirements for wireless, routers, and wireless disconnects.

• Means to reduce incident energy (240.87).
• Labeling at subpanels to identify feeder supply source (408.4(B)).
• Disconnecting means for transformers (450.14).
