Industrial Control Panels UL 508A and Short-Circuit Current Ratings


Description

El seminario se realizará en castellano. El material del seminario solo estará disponible en inglés.

This seminar will be held in Spanish language. The course materials are in English language.

 

Introduction

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, 2nd 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; component requirements in Supplement A and Appendices A and B.

The second 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, 2nd Edition, Supplement B.  This supplement is the only method specifically noted as being approved by the NEC.

Each participant will receive a participant workbook and a copy of the UL 508A Standard ($631 USD value).
