Requirements for Conversion of Power Switchgear Equipment
|Publication Date:||14 June 2018|
This standard covers power switchgear equipment that is converted from a qualified design. It provides direction and guidance in those conversions and specifies required design verification in accordance with applicable American National Standards Institute (ANSI), National Electrical Manufacturers Association (NEMA), UL, or IEEE standards.
This standard also recognizes that production/field testing does not provide design verification. It can only be accomplished by means of design testing and technical evaluation.
