Arc Flash Hazard Analysis

Course #120

This is an instructor led, competency based program designed for anyone working on or near energized electrical conductors and/or equipment. Arc Flash is the least understood and the most dangerous hazard electricians are face with on a daily basis. This course will raise the awareness of Arc Flash hazards and explain how electricians can protect themselves and minimize the Arc Flash effects. The student will be introduced to short circuit calculations, let through curves, and fuse/breaker coordination. In addition to the base program we can add time to assist the company in starting their Arc Flash Analysis, the fee for this is determined by the customers needs and grid size (please contact our office for more details).

Learner Outcomes:

1. Given a bolted short circuit current and the arc time the student will be able to calculate the second degree burn distance.
 
2. Given transformer data the student will be able to calculate its available let through short circuit current.
 
3. The student will be able to calculate Voltage Drop and determine the ICEA, Soares and Onderdonk rates for an application.
 
4. Given a cable application the student will use fuse let through graphs to determine the proper protection.
 
5. The student will calculate the Hazard/Risk Category for a Motor Control Center.
 
6. The student will be able to compare a breaker curve to a fuse curve and will be able to coordinate the curves to one another.
 
7. Given several panel and motor control centers the student will be able to draw the single line drawing.
