Work with new National Electrical Code coverage of green technologies!

The National Electrical Code expands its existing alternative energy coverage – such as rules for solar photovoltaic systems and fuel cells – to help designers, installers, manufacturers, and AHJs safely address an increasing demand. The 2011 National Electrical Code includes:

• Revised Article 625 covering safe battery charging for plug-in hybrid vehicles, to mitigate explosion risks.
• New Article 694: Small Wind Electric Systems with first time requirements for the types of wind systems being installed across the US.
• Revised Article 705 on interconnecting generators, windmills, and solar and fuel cells with other power supplies.

Adopted for all 50 states, the NFPA 70: National Electrical Code contains comprehensive requirements for electrical wiring and equipment. When the code advances, so should you. To avoid violations and other fines, you need the 2011 National Electrical Code.

New Features:

• First-time Article 399 on outdoor, overhead conductors with over 600 volts.
• Revised Article 625 includes updates on safe battery charging for plug-in hybrid vehicles that reduce the risk of explosion.
• New Article 694 has first-time requirements for small wind electric systems.
• Revised Article 705 covers interconnecting generators, windmills, and solar and fuel cells with other powered supplies.
• New Article 840 addresses the increased demand for broadband communications systems with requirements for wireless, routers, and wireless disconnects.

If you're involved in electrical work, your safety is paramount in the workplace. Staying up to date is not only optional, it is essential to your well-being.

As the National Electrical Code keeps pace with new technology and society’s changing demands for electrical power, you’ll be prepared with the tools it takes to stay on time, on budget, and up-to-code. The 2011 National Electrical Code Softcover puts the latest code rules within easy reach, including new coverage of alternative energy sources, green technology, and IT equipment, and changes focused on workplace safety.

From the Introduction
This 2011 edition includes the following usability features as aids to the user. Changes other than editorial are highlighted with gray shading within sections and with vertical ruling for large blocks of changed or new text and for new tables and changed or new figures. Where one or more complete paragraphs have been deleted, the deletion is indicated by a bullet between the paragraphs that remain. The index now has dictionary-style headers with helpful identifiers at the top of every index page.

The purpose of this code is the practical safeguarding of persons and property from hazards arising from the use of electricity. This codes contains provisions that are considered necessary for safety. Compliance therewith and proper maintenance results in an installation that is essentially free from hazard but not necessarily efficient, convenient or adequate for good service or future expansion of electrical use.

This code is not intended as a design specification or an instruction manual for untrained persons. The requirements in this code address the fundamental principles of protection for safety contained in Section 131 of International Electrotechnical Commission Standard 60364-1, Electrical Installations of Buildings.

Covered:
This code covers the installation of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following:

• Public and private premises, including buildings, structures, mobile homes, recreational vehicles, and floating buildings.
• Yards, lots, parking lots, carnivals, and industrial substations.
• Installations of conductors and equipment that connect to the supply of electricity.
• Installations used by the electric utility, such as office buildings, warehouses.

Not Covered:

• Installations in ships, watercraft other than floating buildings, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles.
• Installations underground in mines and self-propelled mobile surface mining machinery and its attendant electrical trailing cable.
• Installations of railways for generation, transformation, transmission, or distribution or power used exclusively for operation of rolling stock or installations used exclusively for signaling and communications purposes.
• Installations of communications equipment under the exclusive control of communications utilities located outdoors or in building spaces used exclusively for such installations.
• Installations under the exclusive control of an electric utility where such installations consist of service drops or service laterals, and associated metering, or are on property owned or leased by the electric utility for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electrical energy, and more.
