Overview
NFPA 70, the National Electrical Code (NEC), is a national model code that governs electrical installations. For life-safety and security work, the articles most often relevant are Article 760 (fire alarm systems), Article 725 (Class 1, 2 and 3 remote-control, signaling and power-limited circuits), Article 800-series (communications circuits) and Article 700/701 (emergency and legally required standby systems). Oklahoma electrical requirements are administered through the Oklahoma Construction Industries Board and local jurisdictions, and the edition in force can differ from the newest national edition.
