California Electrical Code (CEC) contains electrical design and construction standards. Provisions contained in the CEC provide minimum standards to safeguard life or limb, health, property, and public welfare, and to protect against hazards that may arise from the use of electricity by regulating and controlling the design, construction, installation, quality of materials, location and operation of electrical equipment, wiring, and systems. The CEC is a fully integrated code based on the 2008 National Electrical Code®. Included is a free subscription service for all state updates and supplements. Effective Date: January 1, 2011.
