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 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 its grouped rating, it may be ignored for the purpose 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 0.3 Cg x It amperes, the other cables can be sized by using the group rating factor corresponding to (N-M)
cables
3. When cables having differing conductor operating temperatures are grouped together, the current rating shall be based on the lowest operating
temperature of any cable in the group
