Seattle will adopt the 2008 National Electrical Code (NEC) with Seattle amendments in the first quarter of 2009.  The amendments consist of some state amendments (WAC 296-46B) to the 2008 NEC and existing and new Seattle amendments.

On January 15, 2009, the draft Seattle Electrical Code will be presented to the Construction Codes Advisory Board for discussion.  The meeting is open to the public and will be held from noon to 2:00 p.m. in room 2240 of the Seattle Municipal Tower (700 5th Avenue, 22nd floor).

Some of the amendments to be reviewed include new requirements or changes to weatherhead service-entrance conductor length, outdoor installation of oil-insulated transformers, sign clearances from high voltage power lines, and selective coordination, arc-fault and ground-fault protection systems.
