For 9 years now the electrical community has had a mouthful every time the most commonly used ampacity table was mentioned in conversation or spoken of during a seminar. Note 4: • Where the number of current-carrying conductors in a raceway or cable exceeds three, or where single conductors or multiconductor cables are stacked or bundled longer than 24 inches without time metric sized wire is specified in millimeters rather than metric gauges.

TRAY & POWER CABLES TRAY CABLE;++: RU5: (QYLUR3OXV 600/1,000 Volt Copper, LSZH Jacket 4 Conductor, Factory Mutual Group 1 Description: • The allowable values in the Ampacity Table are based on temperature alone and do not take voltage drop into consideration. Where the number of current-carrying conductors exceeds three, the allowable ampacity or the ampacity of each conductor shall be reduced from the 3-conductor rating as shown in Table 400. Four-conductor ampacity assumes three are hot and one is neutral. Ampacity is the maximum continuous current carrying capacity of a wire inside a cable or raceway.
