This document provides a summary of proposed changes to NFPA 70E for the 2015 edition, including 448 public inputs and 173 first revisions. Several global changes are proposed, such as replacing terms like "arc flash hazard analysis" with "arc flash risk assessment", and "hazard/risk category" with "arc flash PPE category". New definitions are also proposed to be added to clarify terms. Changes are proposed to various sections to improve electrical safety requirements for work practices, safety programs, and establishing electrically safe work conditions.
