Key Notes

• KCMIL Definition: \( \text{KCMIL} = \text{Cross-sectional area (mm²)} \times 1.974 \)
• Sorting: The table is sorted by increasing cross-sectional area.
• Practical Use: Verify values with manufacturer data for precise applications.

Key Notes

• Circular Mils Definition: The cross-sectional area in Circular Mils (CM) is calculated as: \( \text{KCMIL} = \text{Cross-sectional area (mm²)} \times 1.974 \)
• Sorting: The table is sorted by increasing cross-sectional area.
• Practical Use: Verify values with manufacturer data for precise applications.
