Thomas Mason, P.E.
This course offers a simplified method of calculating available short-circuit current on a 480V commercial or industrial power distribution system. This calculation is required by the National Electric Code (2008 NEC 110.9, Interrupting Rating). It is also required by OSHA (CFR 1910.132) in order to prepare a detailed Arc-Flash warning label with j/sq-cm and personal protective equipment level.
The course is a set of look-up tables prepared with commercial electrical system modeling software and accompanied by coaching on how to use the tables correctly.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
