ANSI C84.1 2016

ANSI C84.1 has just been updated.  This standard is titled “American National Standard for Electric Power Systems and Equipment – Voltage Ratings (60 Hz).”  The new 2016 Edition replaces the previous revisions, including the 2011 Edition.  This standard establishes nominal voltage ratings and operating tolerances for 60Hz electric power systems above 100V.

ANSI C84.1 is one of the more popular NEMA (National Electrical Manufacturers Association) standards.  Products that meet the requirements for this standard are designed to provide acceptable operation in those voltage ranges.  There are also requirements for preferred voltage ratings up to 1200kV maximum system voltage.

What is new in the 2016 Edition of ANSI C84.1?  A 690/400V category has been added to the Low Voltage Class in table 1.   Also, a paragraph discussing conservation voltage reduction has been added to Annex B.

Why is the standard known as ANSI C84.1 when it is published by NEMA?  The standard is ANSI-approved.  So NEMA has numbered it using the ANSI designation for many years.  They continue with this convention up to this day.
