May 24, 2012 - The National Electrical Manufacturers Association’s (NEMA) Electric Vehicle Supply Equipment (EVSE)/Systems Section created two new working groups to develop standards that focus on network roaming for a public charging station and communication of electric vehicle (EV) metering data.

May 20, 2012 - NEMA’s (National Electrical Manufacturers Association) Primary Industrial Controls Index increased 11.3% on a quarter-to-quarter basis during the first three months of 2012. The index stands 125 above its year-ago level, and 52% above the cyclical trough observed in mid-2009.

March 5, 2012 - The National Electrical Manufacturers Association (NEMA) has published NEMA WD 7 Occupancy Motion Sensors Standard, which aims to promote uniformity for the definition and measurement of characteristics relevant to the use and application of occupancy motion sensors. The standard covers the definition and measurement of field of view and coverage characteristics relevant to the use and application of vacancy and occupancy sensors using individual or any combination of passive infrared, ultrasonic, or microwave technology. These sensors are used in systems for control of lighting, heating, ventilating, and air conditioning (HVAC), and other devices. CLICK HERE to download WD 7 for free.

February 27, 2012 - The National Electrical Manufacturers Association (NEMA) has published NEMA SSL 4 Retrofit Lamps: Minimum Performance Requirements. This publication applies to integral Light Emitting Diode (LED) lamps, which are defined as a lamp with LEDs, an integrated LED driver, and a base that meets appropriate American National Standards (ANSs) and is designed to connect to the branch circuit via a lampholder/socket that meets appropriate ANSs. The criteria applies to both integral LED lamps of non-standard form, and those intended to replace standard general service incandescent lamps, decorative (candelabra style) lamps, and reflector lamps.

February 14, 2012 - The National Electrical Manufacturers Association (NEMA) has published NEMA 250-2011 Enclosures for Electrical Equipment (1000 Volts Maximum), specifying the classification and description of enclosures for electrical equipment. The standard provides potential users with descriptions of types of enclosures and their features, as well as tests used to examine conformance to the respective description. NEMA 250 was last revised in 2008. The new version includes additional tables detailing the testing required for various safety or environmental conditions, along with the related IP code number from ANSI/IEC 60529.
