3.01 TEST AND TEST DATA:
A. A factory load test shall be performed on each motor of 1000 watt input or greater to
assure compliance with the energy-efficiency section of this specification.
B. Typical test data on every motor to be used on this project shall be made available upon
request.
3.02 INSTALLATION:
A. Install motors on motor mounting systems in accordance with motor manufacturer's
instructions, securely anchored to resist torque, drive thrusts, and other external forces
inherent in mechanical work. Secure sheaves and other drive units to motor shafts with
keys and Allen set screws. For motors of 1/3 hp and less, sheaves and drive components
may be secured with Allen set screws on flat surface of shaft. Unless otherwise indicated,
set motor shafts parallel with machine shafts.
B. Deliver starters and wiring devices which have not been factory-installed on equipment to
electrical installer for installation.
C. Install power and control connections for motors to comply with NEC and applicable
provisions of Division 26 sections. Install grounding except where non-grounded isolation
