NEMA MG 1 Document Information:
Title
Motors and Generators
National Electrical Manufacturers Association
Publication Date:
Jan 1, 2006
Scope:
This Standard applies to the classification of degrees of
protection provided by enclosures for rotating electrical machines.
It defines the requirements for protective enclosures that are in
all other respects suitable for their intended use and which, from
the point of view of materials and workmanship, ensure that the
properties dealt with in this standard are maintained under normal
conditions of use.
This standard does not specify:
• degrees of protection against mechanical damage of the
machine, or conditions such as moisture (produced for example by
condensation), corrosive vapours, fungus or vermin;
• types of protection of machines for use in an explosive
atmosphere;
• the requirements for barriers external to the enclosure
which have to be provided solely for the safety of personnel.
In certain applications (such as agricultural or domestic
appliances), more extensive precautions against accidental or
deliberate contact may be specified.
This standard gives definitions for standard degrees of
protection provided by enclosures applicable to rotating electrical
machines as regards the:
protection of persons against contacts with or approach to live
parts and against contact with moving parts (other than smooth
rotating shafts and the like) inside the enclosure and protection
of the machine against ingress of solid foreign objects;
protection of machines against the harmful effects due to
ingress of water.
It gives designations for these protective degrees and tests to
be performed to check that the machines meet the requirements of
this standard.
