EPAct – US Energy Effi ciency
The Energy Policy Act of 1992 (EPAct) covers effi -
ciency levels of general purpose industrial electric
motors and became effective October 24, 1997. The
basic goal of the law is to promote energy conser-
vation. This law mandated energy effi ciency re-
quirements for many devices including some types
of industrial electric motors. The effi ciency levels
are defi ned in NEMA MG-1 table 12-10. The regu-
lations to implement this law have been developed
by the Department of Energy (DOE).
The law covers minimum effi ciency levels for general
purpose motors including:
• Single-speed, polyphase NEMA T frame
(and IEC equivalents)
• 1 to 200 hp (0.75 to 150 kW)
• 1200, 1800 or 3600 rpm
• NEMA design A and B
• Continuous rated
• Foot-mounted
• 230/460V-60Hz
The law excludes the following motor types from
minimum effi ciency levels:
• Integral gearmotors
• Brake motors
The NORD “H” line of energy effi cient motors are
designed to meet the effi ciency levels defi ned by
EPAct. NORD offers these motors as an option in
combination with our high effi ciency gear units for
superior energy savings.

NORD motors carry the CE mark in accordance
with the Low Voltage Directive and, if installed
properly, the Electromagnetic Compatibility Direc-
tive (EMC). The CE mark is required for installa-
tion in European Union (EU) states.
Many NORD motors from frame size 63 to 315 are
an Underwriters Laboratories Recognized compo-
nent per UL standard 1004.
Frames 63-132 File number E191510
Frames 160+ File number E227215
The Canadian Standards Association CUS mark
indicates that CSA has tested and approved NORD
motors according to both US and Canadian stan-
dards. It is equivalent to the Underwriters Labora-
tories RU recognition mark (UL standard 1004) and
the CSA mark according to CSA Standard C22.2

NORD Energy Effi cient motors up to frame 160
have been evaluated by the United States De-
partment of Energy and recieved a Certifi cate of
Compliance to certify the effi ciency ratings. The
certifi cate of compliance is CC 092
B.
NORD energy effi cient motors carry the CSA en-
ergy effi ciency verifi cation mark. This mark en-
sures that CSA has verifi ed that NORD motors are
designed and manufactured to meet energy effi -
ciency requirements number EEV112560.
