Summary of NFPA 70E 2015 Revisions:

  • Several significant terminology changes have been made in the 2015 edition. For example, all references to hazard/risk category (HRC) have been deleted throughout the standard and the new term “Arc Flash PPE” is now used.
  • The importance of maintenance has been emphasized through key wording changes.
  • Definitions. Several key definitions have been deleted, changed or added.
  • Deleted: Bare‐hand work and Prohibited Approach Boundary.
  • Revised: Restricted Approach Boundary, Incident energy, Qualified person.
  • New Definitions: Hazard, Hazardous, Risk and Risk Assessment.

Article 110 General Requirements for Electrical Safety‐Related Work Practices

The following have been reorganized to a new sequence:

  • 110.1 Electrical Safety Program: Some language changes, additions, renumbering of sections, deletion of reference to both the limited approach boundary and arc flash boundary.
  • 110.2 Training Requirements: Now requires annual refresher training in several areas and requires verification and documentation, and specific process for qualified person.
  • 110.3 Host and Contract Employers Responsibilities: Title change and requirement for meeting between host/contract employer.
  • 110.4 Use of Electrical Equipment: New section to require Ground‐Fault Interrupter (GFCI) Protection for maintenance and Construction.

Article 120 Establishing an Electrically Safe Work Condition

  • Title and terminology changes.
  • Lockout/Tagout (LOTO): Requires retraining and documentation, hold cards, temporary protective grounding equipment.

Article 130 Work Involving Electrical Hazards

  • 130.1: Defines when an electrically safe work condition must be established and the electrical safety‐related work practices when an electrically safe work condition cannot be established.
  • 130.2(A)(4): Defines requirements for normal operation of electric equipment.
  • 130.2(B) Energized electrical work permit: Deletes references to limited approach and arc flash boundaries and defines when energized work is permitted in accordance with 130.2(A) an energized electrical work permit (EEWP) is required.
  • 130.2(B)(2) Elements of Work Permit: Deletes references to limited approach and arc flash boundaries and defines when energized work is permitted in accordance with 130.2(A) an energized electrical work permit (EEWP) is required.
  • 130.2(B)(3) Exemptions to Work Permit: Defines exemptions.
  • 130.4(A) Shock Risk Assessment: Title was changed from “Shock Hazard Analysis.”
  • Table 130.4(C)(a) Approach Boundaries to Energized Electrical Conductors: The prohibited approach boundary was deleted from the table, changes to voltages in table.
  • 130.5 Arc Flash Risk Assessment: Title change from “Arc Flash Hazard Analysis.” Defines purpose of assessment and what to do if hazard exists. Language changes to Informational Note No.1.
  • 130.5(A) Documentation: Requires documentation of results of the arc flash risk assessment.
  • 130.5(B) Arc Flash Boundary: New language to permit the arc flash boundary to be determined by Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B) when the requirements of the tables apply.
  • 130.5(C) Arc Flash PPE: New language - selecting PPE for the same piece of equipment is to use either the results of an incident energy analysis OR the arc flash PPE category method (not both). New language to prohibit using an incident energy analysis to specify an arc flash PPE category in Table 130.7(C)(16).
  • 130.5(D) Equipment Labeling: New language further clarifies how to label the PPE requirements.
  • Table 130.7(C)(15)(A)(a) Arc Flash Hazard Identification for Alternating Current (AC) and Direct Current (DC)Systems:
    • New table to be used for determining when arc flash PPE is required for both AC and DC electrical systems.
    • Table uses a simple yes or no if arc flash PPE is required and are based on the task to be performed and the equipment condition.
    • Defines equipment condition parameters.
  • New PPE Category Tables based on the PPE category, deletion of the hazard/risk references, deletion of Category 0 and columns for rubber gloves and insulated tools and rounding of some Arc Flash Boundaries to the nearest foot.
  • Table 130.7(C)(15)(A)(b)—Arc Flash Hazard PPE Categories for Alternating Current (AC) Systems: This table defines the PPE categories for AC systems. Specific tasks have been deleted, and it now lists equipment, arc flash PPE category and the arc flash boundary.
  • Table 130.7(C)(15)(B)—Arc Flash Hazard PPE Categories for Direct Current (DC) Systems: This table defines the PPE categories for DC systems. Specific tasks have been deleted and it now lists equipment, arc flash PPE category and the arc flash boundary.
  • 130.7(D)(1) Insulated Tools and Equipment: This section now references the restricted approach boundary instead of the limited approach boundary.
  • 130.7(E)(2) Barricades: This section now includes the arc flash boundary.

Chapter 2: Safety‐Related Maintenance Requirements

  • 200.1 Scope: Informational Note No. 3 now references IEEE 3007.2—IEEE Recommended Practice for the Maintenance of Industrial and Commercial Power Systems.
  • 205.3 General Maintenance Requirements: This expanded section includes new language that states, “The equipment owner or the owner’s designated representative shall be responsible for maintenance of the electrical equipment and documentation.” Added a new informational note regarding text and calibration labels.
