Chicago NFPA 70 National Electrical Code with Chicago Amendments 2017

The Chicago City Council has passed a major update to the Chicago Electrical Code. The 2018 edition of the Chicago Electrical Code is based on the 2017 edition of NFPA 70®: National Electrical Code (NEC) -- the widely adopted Code containing regulations for electrical wiring, overcurrent protection, grounding, and installation.

Updated to incorporate Chicago amendments, the purpose of the Chicago Electrical Code is the practical safeguarding of persons and property from hazards arising from the use of electricity.

Provisions cover the installation of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways.
