Where is the cross-sectional area in circular mils located for voltage-drop calculations?

The cross-sectional area in circular mils used for voltage-drop calculations is found in Chapter 9, Table 8. This table provides the necessary information about the conductor sizes, including their corresponding cross-sectional areas, which are crucial for accurately calculating voltage drop in electrical circuits.

Understanding where to find this information is vital for electrical contractors, as voltage drop calculations ensure that circuits operate effectively and within acceptable limits, thus enhancing safety and performance. The tables in Chapter 9 are specifically designed to aid in these calculations, making it easier to select appropriate conductor sizes based on current-carrying capacities and the desired voltage drop for the application at hand.
