NFPA 79: Electrical Standard for Industrial Machinery with Industrial Control Panels UL 508A and Short-Circuit Current Ratings (Bundled Workshop)


This workshop combines our two most popular programs - NFPA 79 and UL 508A - to give you a comprehensive understanding of industrial machinery electrical safety requirements in a bundled solution.  

The first two days of this technical workshop will cover the origin, organization, intent, and purpose of NFPA 79 Electrical Standard for Industrial Machinery 2018 Edition.  Industry experts will guide you through the Standard and provide the practical knowledge and understanding you need to make informed safety decisions using NFPA 79 in conjunction with the National Electrical Code and other related documents.     

The third day of the workshop focuses on how to construct general use industrial control panels in accordance with the Standard for Industrial Control Panels, UL 508A, 3rd Edition.  It covers UL 508A, general use ICP construction, power circuit, control circuit, rating and marking requirements, sections 1-61; enclosure construction requirements, sections 62-64; standards for components, Appendix A; use of non-UL components, Appendix B; and component usage, Appendix C.

The final day instructs industrial control panel customers on how to establish short-circuit ratings for individual industrial control panels in accordance with the requirements outlined in the new Standard for Industrial Control Panels, UL 508A, 3rd Edition, Supplement SB.  This supplement is the only method specifically noted as being recognized by the NEC.

Each participant will receive a participant workbook, a copy of the NFPA 79: Electrical Standard for Industrial Machinery, 2018 Edition, and a copy of the UL 508A Industrial Control Panels Standard, 3rd Edition  ($960 USD value).
