* Tinsel Cord.
** Elevator Cables Only
*** 7 amperes for elevator cables only, 2 amperes for other types
+ The allowable currents under sub-heading A apply to 3 conductor cords and other multiconductor cords connected to utilization equipment so that only 3 conductors are current carrying.
† The allowable currents under sub-heading B apply to 2 conductor cords connected to utilization equipment so that only 2 conductors are current carrying. |
