Development of The Code
electrical standards were based on the National Fire Protection Association's standard
NFPA 70E, "Electrical Safety Requirements for Employee Workplaces." The NFPA 70
Committee derived Part I of their document from the 1978 edition of the National
Electrical Code (NEC). The standards extracted from the NEC were those considered the most
applicable to employee safety and least likely to change with each new edition of the NEC.
OSHA's electrical standards are performance oriented; therefore they contain few direct
references to the NEC. However, the NEC contains specific information as to how the
required performance can be obtained.
