> [!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. |
