by Jbs033010 a3 — April 5, 2010—The National Electrical Manufacturers Association (NEMA) has launched three publications in recent weeks covering air conditioning general-purpose medium-voltage contactors and Class E controllers, electrical industrial topics, and double-capped fluorescent lamps.
The updated ICS 3.1-2009 Guide for the Application, Handling, Storage, Installation, and Maintenance of Medium-Voltage AC Contactors, Controllers, and Control Centers, last revised in 1997, provides information regarding the application, handling, storage, installation, and maintenance of ac general-purpose medium-voltage contactors and Class E controllers. The guide has been updated to reflect changes in technology. ICS 3.1 may be downloaded at no charge, or a hardcopy purchased for $75.
The new ICS 20-2009 Informational Guide to Electrical Industrial Topics provides information on various topics of interest related to the application and proper usage of electrical equipment in the global marketplace. Subjects include enclosure type ratings, wire sizing, and feeder and branch circuits. ICS 20 may be downloaded at no charge, or a hardcopy purchased for $67.
The updated ANSI_ANSLG C78.81-2010 American National Standard for Electric Lamps—Double-Capped Fluorescent Lamps—Dimensional and Electrical Characteristics, is being published on behalf of the American National Standard Lighting Group (ANSLG). Last revised in 2005, ANSI_ANSLG C78.81 details the physical and electrical characteristics of the principal types of fluorescent lamps intended for application on conventional line frequency circuits and electronic high-frequency circuits. The revision includes three new fluorescent lamp data sheets. The standard may be downloaded at no charge, or a hardcopy purchased for $580.
