FTWIC-2235June 2009classifications. Polyphase motors shall conform to Federal Specification CC-M-1807,and shall be Type II, Class 3, minimum insulation Class B, squirrel cage type, havingnormal starting torque and low starting current characteristics, unless otherwise specified.The horsepower rating indicated on electrical plans is for guidance only and does notlimit the equipment size.D. Motors, 1/8 horsepower or larger shall have overload protection in each phase, or otherequally rated method in accordance with the NEC. The overload protection device shallbe provided either integral with the motor, (except that motors to be installed in locationsthat are not readily accessible shall have the overload protection device located for easyaccess to the reset button), or with the control, or shall be mounted in a separateenclosure. Unless otherwise indicated, the protective device shall be of the manual resettype. Single or double pole tumbler switches specifically designed for alternating currentoperation only may be used as manual controllers for single phase motors having acurrent rating not in excess of 80 percent of the switch rating. Automatic control devicessuch as thermostats, float or pressure switches may control the starting and stopping ofmotors directly, provided the devices used are designed for that purpose and have anadequate horsepower rating. When the automatic control device operates the motordirectly, a double-throw, three position tumbler or rotary switch shall be provided for themanual control. When the automatic control device actuates the pilot control circuit of amagnetic starter, a three position selector switch marked Manual-Off-Automatic shall beprovided. Connections to the selector switch shall be such that only the normal automaticregulatory control devices will be bypassed when the switch is in the manual position andall safety control devices, such as low or high pressure cutouts, high temperature cutouts,and motor overload protective devices, shall be connected in the motor control circuit inboth the manual and the automatic positions of the selector switch. Provide pilot lightassemblies having a rated life of 50,000 hours. Provide red (running) and green(stopped) lenses.E. Each motor shall be provided with a fused disconnecting means or a combination starteras indicated on the plans with a manually operable switch. For single phase motors, asingle or double pole toggle switch, rated only for alternating current, will be acceptablefor capacities less than 30 amperes, provided the ampere rating of the switch is at least125 percent of the motor rating. Switches shall disconnect all ungrounded conductors. Acomplete set of fuses shall be installed and two sets of spares shall be furnished for eachfusible device. Fuses shall have a voltage rating not less than the circuit voltage.Cartridge fuses shall have an interrupting rating not less than 100,000 amps, when usedin branch circuits, and not less than 200,000 amps when used in a service entranceswitch.3.02 FIELD QUALITY CONTROL:Upon completion of the installation, perform continuity tests and functional checkout to assurethe proper operation of all equipment.END OF SECTION16150-3
