7、ODUCTION1 Scope1.1 This Outline covers the requirements for multiple conductor cables intended for use indoors andoutdoors as vertical drop cable from a crane or hoist down to a pendant pushbutton station, or as a controlcable in a crane and hoist system in accordance with Article 610 of the Nationa
8、l Electrical Code (NEC),ANSI/NFPA 70. The wire is rated 300 or 600 Volts, and 60, 75, 90, or 105C (140, 167, 194, or 221F).2 Units of Measurement2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.3 Components3.1 Except as indica
