# Conduit Sizing

Table 1 Percent of Cross Section of Conduit and Tubing for Conductors and Cables

| Number of Conductors and/or Cables | Cross-Sectional Area (%) |
| ---------------------------------- | ------------------------ |
| 1                                  | 53                       |
| 2                                  | 31                       |
| Over 2                             | 40                       |

> [!info] Informational Note No. 1:
> Table 1 is based on common conditions of proper cabling and alignment of conductors
> where the length of the pull and the number of bends are within reasonable limits.
> It should be recognized that, for certain conditions,
> a larger size conduit or a lesser conduit fill should be considered.

> [!info] Informational Note No. 2:
> When pulling three conductors or cables into a raceway,
> if the ratio of the raceway (inside diameter)
> to the conductor or cable (outside diameter)
> is between 2.8 and 3.2, jamming can occur.
> While jamming can occur when pulling four or more conductors or cables into a raceway,
> the probability is very low.
