Where the horizontal clearance between adjacent cables exceeds 2 De, no correction factor need be applied. Notes: 1) The factors in the table are applicable to groups of cables all of one size. The value of current derived from application of the appropriate factors is the maximum continuous current to be carried by any of the cables in the group. 2) If, due to known operating conditions, a cable is expected to carry not more than 30% of it’s grouped rating, it may be ignored for the purposed of obtaining the rating factor for the rest of the group. For example, a group of N loaded cables would normally require a group reduction factor of Cg applied to the tabulated It. However, if M cables in the group carry loads which are not greater than 0.3Cglt amperes, the other cables can be sized by using the group rating factor corresponding to (N-M) cables. 3) Factors are given for single layer of cables and do not apply when cables are installed in more than one layer touching each other. 4) For circuits having more than one cable in parallel per phase, each set of three conductors should be considered as a circuit for the purpose of this table.

CM area is actual Conversion factors: mm2 x 1973.5 = CM x 0.0005067 = mm2. AWG - America Wire Gauge. A standard measurement of the size of a conductor: 4/0 & smaller. CM (Circular Mil) used to define cross-sectional areas of conductors. Area of circle 171000 inches in diameter. MCM – 1000 circular mils.
