Description

In this free lecture, Ryan Mayfield discusses two topics that are critical in the design and installation of large scale commercial installations: DC arc flash and insulation resistance testing.

The lecture includes discussions on the application of NFPA 70E in calculating DC arc faults and the associated hazard risk categories. Sample calculations are provided to illustrate real world examples and applications. The lecture also includes information on insulation resistance testing (IRT) during system commissioning and operations and maintenance activities. Participants will see an IRT procedure applied to help solidify the concepts presented in the lecture.

By the end of the lecture, participants will:
