The NJATC trains top-quality electrical workers across the country. This Second Edition text covers electrical safety requirements and safety-related work practices of OSHA and the National Fire Protection Association electrical safety in the workplace code, NFPA 70E®. Specific topics include electrical safety culture, hazard awareness, design considerations, electrical safety program, training, calculation of short-circuit currents, arc flash hazard analysis methods, PPE, and equipment maintenance. Chapters explore calculations required to comply with NFPA 70E, and techniques that can be applied to significantly reduce or eliminate electrical hazards. Each chapter includes two real-life case studies and recommendations for how these incidents could have been avoided. A must for electrical safety professionals, instructors, electrical workers, and contractors.
