Class: IEEE 1584 Arc Flash Studies

Brainfiller.com (forum sponsor)

There are a few dates remaining for my class about IEEE 1584 and arc flash studies. This is unique class where I not only show you how to perform the study but we perform each of the calculations manually using worksheets that I developed. This enables the user the ability to understand the affect of enclosure sizes, electrode configurations and more.

Questions about the class? Contact our Program Director: 800-874-8883
