The National Electrical Manufacturers Association (NEMA) published the 2015 edition of its Electrical Standards & Products Guide (ESPG), a comprehensive listing of NEMA electrical standards as well as an extensive directory of manufacturers and their products.

Step-voltage regulators have been added to the scope in this edition and there is now more alignment with IEEE transformer standards. NEMA TR 1 is one of the few standards on the market that lists audible sound levels for these particular transformers.

The act will replace the current EPAct legislation which has been in force since 1997 and covers low voltage, "General Purpose" 3-phase electric motors from 1-200HP (0.75 - 150 kW). It will enforce a rise in the minimum efficiency of these machines from NEMA Energy Efficient to NEMA Premium Efficient. The new law will go further as it also encompasses motors not previously within the EPAct scope. The result is that almost all low voltage, 3-phase electrical induction motors will be covered by this new legislation. It can be summarised as follows: - 1-200 HP General Purpose motors currently covered by EPAct will change from NEMA Energy Efficient to NEMA Premium Efficient. - 1-200 HP motors not covered in point 1 above will comply with NEMA Energy Efficient. - 201-500 HP motors will comply with NEMA Energy Efficient.

Schneider Electric has announced availability of the Square D Premium 30 Energy Efficient Transformers. The new line of transformers is designed to help reduce lost energy, exceed minimum efficiency program standards, and provide optimal performance and superior quality in commercial, industrial, healthcare, educational, and government buildings.
