| 2 | Where Table 1 applies | Complete conduit or tubing systems only, not short sleeves protecting exposed wiring from damage. |
| 3 | Grounding conductors | Equipment grounding or bonding conductors count in the fill, at their actual size, insulated or bare. |
| 4 | Nipples ≤ 600 mm (24 in.) | Between boxes, cabinets and similar enclosures: fill up to 60 % (the Table 4 60 % column). |
| 5 | Cables not in Chapter 9 | Multiconductor and optical fiber cables: use their actual dimensions. |
| 6 | Mixed sizes | Conductor areas from Table 5 or 5A (or actual), raceway areas from Table 4. |
| 7 | Counting same-size conductors | Round the maximum number up to the next whole number when its decimal is 0.8 or more. Sizing for one conductor: a result of 0.8 or more permits that one conductor. |
| 8 | Bare conductors | Where bare conductors are allowed, the Table 8 dimensions may be used. |
| 9 | Cables and cords | A multiconductor cable, optical fiber cable or flexible cord counts as one conductor; an elliptical one as a circle of its major diameter. Single conductors grouped without an overall covering are not a cable: count each one. |
| 10 | Table 5 values | Worst case, for round concentric-lay stranding (compact stranding is in Table 5A); known actual dimensions may be used instead. |
| Table 1, Inf. Note 2 | Jamming | Pulling three conductors or cables: jamming can occur when raceway inside diameter ÷ conductor outside diameter is 2.8 to 3.2. |
