User note:
About this chapter: Electrical systems and components are integral to most structures; therefore it is necessary for the code to address their installation and protection. Structures depend on electricity for the operation of many life safety systems including fire alarm, smoke control and exhaust, fire suppression, fire command and communication systems. Since power supply to these systems is essential, Chapter 27 addresses where standby and emergency power must be provided.
Chapter 27 of the IBC is amended to read as follows:
2701.1 Scope.
The provisions of this chapter and the Washington Cities Electrical Code shall govern the design, construction, erection and installation of the electrical components, appliances, equipment and systems used in buildings and structures covered by this code. The International Fire Code, International Building Code, and the Washington Cities Electrical Code shall govern the use and maintenance of electrical components, appliances, equipment and systems. The International Existing Building Code and the Washington Cities Electrical Code shall govern the alteration, repair, relocation, replacement and addition of electrical components, appliances, or equipment and systems.
