through the nylon),or on the outer surface of the jacket of a multiconductor cable shall be repeated at intervals of no more than610mm(24in.)throughout the length of the single-conductor or the multiconductor cable.
Exception:Sizes smaller than16AWG shall be permitted to be marked on the reel or on the smallest unit of the shipping carton.
13.4.2The legend shall include the manufacturer’s name or trademark,the wire type,voltage rating,and gauge or size. 13.4.3Where the conductor is16through10AWG and the stranding is intended for flexing rvice,the legend shall in-clude“flexing”or“Class K.”
13.4.4Wire insulation shall be identified and adequate for the voltage on that conductor.
13.5Conductor Ampacity.
13.5.1The continuous current carried by conductors shall not exceed the values given in Table13.5.1.
13.5.2Ampacity adjustment for90°C insulated conductors
ampacities shall be bad on the ampacities in the75°C col-umn of Table13.5.1.
13.5.3Motor circuit conductors supplying a single motor shall have an ampacity not less than125percent of the motor full-load current rating.
13.5.4Combined load conductors shall have an ampacity not less than125percent of the full-load current rating of all resis-tance heating loads plus125percent of the full-load current rating of the highest rated motor plus the sum of the full-load current ratings of all other connected motors and apparatus bad on their duty cycle in operation at the same time. 13.5.5Where ampacity derating is required for ambient tem-perature correction for other than30°C or adjusted for more than three current-carrying conductors in a raceway or cable,the factor(s)shall be taken from Table13.5.5(a)and Table13.5.5(b).Sizing of conductors within control enclosures in wiring har-ness or wiring channels shall be bad on the ampacity in cable or raceway.The factors shall apply to NFPA70,Article725, Class1,control conductors,only if their continuous load exceeds 10percent of the conductor ampacity.
13.5.6The maximum size of a conductor lected from Table13.5.1and connected to a motor controller shall not exceed the values given in Table13.5.6.

Exception:Where other motor controllers are ud,the maximum con-ductor size shall not exceed that specified by the manufacturer.
13.5.7Conductor/Terminal Compatibility.The conductor(s) shall be compatible with the device terminal(s),and the con-ductor size(s)shall not exceed the range recommended by the device manufacturer.
