What Is It?

The Seattle Electrical Code provides minimum standards to protect people and property from the hazards of electricity. The code regulates the construction, installation, quality of materials, location, and operation of equipment and systems using electricity in the City of Seattle’s built environment.

The code does not include design specifications or instructions like those found in installation manuals. It applies to all electrical wiring and equipment, including communications systems, installed or used within Seattle.

Exemptions to the code exist in the following areas:

  • Ship
  • Railway
  • Communication utility equipment
  • Electrical utility installations, and mining equipment

See section 80.3 for details.
