NOTE: Electrical characteristics, motor starter
type, enclosure type, and maximum rpm should be
shown on the drawings in the equipment schedules.
**************************************************************************
Electrical motor-driven equipment specified shall be provided complete with
motor, motor starter, and controls. Unless otherwise specified, electric
equipment, including wiring, shall be according to Section 16402 INTERIOR
DISTRIBUTION SYSTEM. Electrical characteristics and enclosure type shall
be as shown. Use of the manufacturer's standard motor for motors less than
745 W 1 Hp or for single phase motors is acceptable. Motor starters shall
be provided complete with thermal overload protection and other
appurtenances necessary. Each motor shall be according to NEMA MG 1 and
shall be of sufficient size to drive the equipment at the specified
capacity without exceeding the nameplate rating of the motor. Manual or
automatic control and protective or signal devices required for the
operation specified, and any control wiring required for controls and
devices, but not shown, shall be provided. Where two-speed or
variable-speed motors are indicated, solid-state variable-speed controller
may be provided to accomplish the same function. Solid-state
variable-speed controllers shall be utilized for 0.745 kW through 7.45 kW
(fractional hp through 10 hp) fractional hp through 10 hp ratings.
Adjustable frequency drives shall be used for larger motors.
