A 500,000-circular mil cable is composed of how many strands?

The concept of "circular mil" is used to describe the cross-sectional area of a wire or cable, particularly in the context of larger gauge sizes. A circular mil is defined as the area of a circle with a diameter of one mil (one-thousandth of an inch).

When determining the number of strands in a multi-strand cable, the total circular mil area must be divided by the area of an individual strand. For smaller gauge wires, it is common to use the AWG (American Wire Gauge) system to establish the size of each strand.

In the case presented, for a 500,000-circular mil cable, it is understood that this cable would be composed of smaller strands combined to reach the total cross-sectional area. If we consider a common gauge size for individual strands, such as 10 AWG, which has a circular mil area of approximately 100,000 circular mils, then approximately 5 of these strands would be needed to reach 500,000 circular mils. However, to reach a more practical and manageable number of strands while maintaining good flexibility and conductivity, larger sizes, or different configurations allowing for 37 strands of a certain gauge is a common specification in multi-strand cables.
