State of Washington
The 2014 National Electrical Code, with Washington State amendments, becomes effective on July 1, 2014.
The rules, found in Washington Administrative Code (WAC) 296-46B, are now available electronically from the Washington State Labor and Industries website.
Printed copies are forthcoming.
The previous Washington State Electrical Code was based on the 2008 NEC.
With this adoption, Washington moves from the 2008 to the 2014 NEC, passing over the 2011 NEC edition.
In another significant aspect of this code adoption, Washington moves from the 2005 NEC provisions for Arc-Fault Circuit-Interrupter protection in dwelling units to the 2014 NEC provisions, ensuring a higher level of electrical safety for Washington residents.
This adoption will help the electrical industry in Washington stay current with technological advances in areas such as solar and wind energy, electric vehicle charging, lighting and use of higher voltages.
The industry will also be able to take advantage of new products and technologies that are now recognized by the 2014 NEC, such as modular data centers and energy management systems.
