Values are approximate and rounded for safety. When placing NM cable in conduit, the conduit fill is based on the oval cross-section of the cable, not its individual wires. Per NEC 334.80, you must use the major diameter of the cable for fill calculations.

When running electrical wires through conduit—whether PVC, EMT (electrical metallic tubing), or flexible metal conduit—you cannot simply stuff as many cables as will fit. Overcrowding leads to overheating, insulation damage, and code violations. That’s where the Cable in Conduit Chart comes in. cable in conduit chart
