Extended voltage range motors will not be permitted. Controllers and
contactors shall have a maximum of 120 volt control circuits, and shall
have auxiliary contacts for use with the controls furnished. When motors
and equipment furnished are larger than sizes indicated, the cost of
additional electrical service and related work shall be included under the
section that specified that motor or equipment. Power wiring and conduit
for field installed equipment shall be provided under and conform to the
requirements of Section 16402 INTERIOR DISTRIBUTION SYSTEM.

ELECTRICAL INSTALLATION REQUIREMENTS
Electrical installations shall conform to IEEE C2, NFPA 70, and
requirements specified herein.
1.6.1
New Work
Provide electrical components of mechanical equipment, such as motors,
motor starters [(except starters/controllers which are indicated as part of
a motor control center)], control or push-button stations, float or
pressure switches, solenoid valves, integral disconnects, and other devices
functioning to control mechanical equipment, as well as control wiring and
conduit for circuits rated 100 volts or less, to conform with the
requirements of the section covering the mechanical equipment. Extended
voltage range motors shall not be permitted. The interconnecting power
wiring and conduit, control wiring rated 120 volts (nominal) and conduit,
[the motor control equipment forming a part of motor control centers,] and
the electrical power circuits shall be provided under Division 16, except
internal wiring for components of package equipment shall be provided as an
integral part of the equipment. When motors and equipment furnished are
larger than sizes indicated, provide any required changes to the electrical
service as may be necessary and related work as a part of the work for the
section specifying that motor or equipment.
1.6.2
Modifications to Existing Systems
Where existing mechanical systems and motor-operated equipment require
modifications, provide electrical components under Division 16.
1.6.3
High Efficiency Motors
1.6.3.1
High Efficiency Single-Phase Motors
Unless otherwise specified, single-phase fractional-horsepower
alternating-current motors shall be high efficiency types corresponding to
the applications listed in NEMA MG 11.
1.6.3.2
High Efficiency Polyphase Motors
Unless otherwise specified, polyphase motors shall be selected based on
high efficiency characteristics relative to the applications as listed in
NEMA MG 10. Additionally, polyphase squirrel-cage medium induction motors
with continuous ratings shall meet or exceed energy efficient ratings in
accordance with Table 12-6C of NEMA MG 1.
