Course Purpose: The purpose of this course is to provide the student with an in-depth understanding of the current requirements of NFPA 70E® 2018. A complete presentation of the standard will be provided, along with the examples and exercises covering the tables and calculation methods used in the standard for determining Approach Boundaries and selecting proper Personal Protective Equipment (PPE).

This course will present the following major topics:

  • NFPA 70E 2018 Standard for Electrical Safety in the Workplace
  • Safe Electrical Work Practices
  • Calculating Arc Flash Boundary (Bolted Fault)
  • Selecting Appropriate Personnel Protective Equipment
  • Calculations based on Bolted Fault Current – Short-circuit Current, Power in the Arc, Arc Flash Boundary, Determining Clearing Time, Incident Energy (Arc in Open Air & Arc in a Cubic Box), Calculation Limitations
  • Calculations based on Arcing Current (IEEE 1584) – Arcing Current, Incident Energy (Normalized and Actual), IEEE 1584 Arc Flash Boundary Calculation

Who Should Attend: Individuals or engineers responsible for ensuring compliance with, developing training on, or supervising employees who are required to work in accordance with NFPA 70E 2018 or who will be exposed to work areas designated by the approach boundaries should attend this course.

Prerequisites: To successfully complete this course, the following prerequisites are required:

• Familiarity with basic electricity
• Proficiency in student’s respective classification
• Enrolled in an up-grader/apprentice program

Technology Requirements: All technology is provided for student use in the classroom by Rockwell Automation. It is not necessary for students to bring any technology with them when attending this course.

Student Materials: To enhance and facilitate your learning experience, the following materials are provided as part of the course package:

  • Student Manual, which contains the key concepts, definitions, and examples presented in the course./li>
  • NFPA 70E 2018 Standard for Electrical Safety in the Workplace

Hands-On Practice: Throughout this course, you will have the opportunity to practice the skills you have learned through class interaction and observational exercises. The interactive exercises focus on awareness, safe work practices, maintenance requirements, calculation methods, boundaries, and regulations learned during the lessons.

Course Length: This is a two-day course.
