 Space means a clearance between adjacent surfaces of at least one cable diameter (De). 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.

Another important factor for the determination of the conductor size is the maximum
allowable current during a short circuit when the maximum allowable current during
a short circuit when the maximum allowable conductor temperature is higher than
during normal operation.
The maximum permissible short circuit current of XLPE cables up to 1Kv with
copper conductors can be calculated with the formula:


Where l = Short Circuit rating (KA)
S = Conductor Area (sq mm)
t = Duration of Short Circuit (sec)
Copper Conductor Technical Table 14.3
Current
in
Kiloampers
Duration of Short circuit in Seconds
The values of fault current given in the graph are based on the cable being fully loaded at the start of the short circuit (conductor temperature 900
c), and a final conductor
temperature of 2500
c, and it should be ensured that the accessories associated with the cable are also capable of operation at these values of fault current.

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.
