The introduction of the new Article 409 for Industrial Control Panels in the 2005 edition of the National Electrical Code (NEC) drew increased attention to installations of industrial control panels. Industrial control panels (ICPs) with the UL Mark are installable to the NEC and have a distinct competitive edge in the marketplace.

The first 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, 1st Edition. It covers UL 508A, general use ICP construction, rating and marking requirements, sections 1-61; enclosure construction requirements, sections 62-64; component requirements, supplement SA and appendices A and B.

The second day instructs existing 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, 1st Edition, Supplement SB. This supplement is the only method specifically noted as being approved by the 2005 NEC. Each participant will receive a participant workbook and a copy of the UL 508A Standard.

Topics covered include:

• Introduction to industrial control panels
• Development of UL 508A
• Project categories and UL directory information
• Part I of UL 508A-general use
• Part I of UL 508A-construction
• Power circuits
• Control circuits
• Ratings and markings
• Standard vs. high-fault markings
• Ratings of individual components, including unmarked devices
• Feeder and branch circuit determinations
• Feeder circuit devices such as fuses, circuit breakers and transformers that limit let-through current
• How to utilize feeder devices to obtain high-fault ratings
• How to determine control circuit ratings
• Markings
