Delaware Adopts 2011 National Electrical Code®
The Delaware State Fire Prevention Commission adopted the 2011 National Electrical Code (NEC®), effective December 11, 2012. This regulation has the force and effect of law in the counties, cities, and political subdivisions of the State. However, any county, city, or local jurisdiction can amend this regulation providing such regulation or ordinance is more stringent or imposes higher standards than those required by the 2011 National Electrical Code and are not inconsistent with the NEC and are not contrary to recognized standards and good engineering practices.
The 2011 NEC is adopted in its entirety with the exception of two amendments regarding the installation of smoke alarms on branch circuits protected by Arc-Fault Circuit-Interrupters. The amendments are the same as those made with the adoption of the 2005 and 2008 NEC. Sections 210.12(B) and 550.25(B) are amended by adding a second, third and fourth sentence to read as follows: Smoke alarms shall not be placed on branch circuits protected by arc-fault circuit interrupter. All smoke alarms shall be supplied by branch circuits dedicated to smoke alarm equipment. The connection of the smoke alarm branch circuit to the power service shall be mechanically protected by utilizing lock-on devices.
