2002 Changes to the NEC®
Article 725 Low Res - Modem Hi Res - Cable/DSL        Page 3 of 5
Class 1, Class 2, And Class 3 Remote-Control, Signaling, And Power-Limited Circuits

725.3 Locations of Other Articles

The following requirement was added:

(A) Number and Size of Conductors in Raceway. The number and size of conductors in a raceway must be in accordance with the limitations listed in 300.17.

Intent: The new rule requires that the raceway fill limitations of 300.17 apply to Class 1, Class 2 and Class 3 conductors. When installing control and signaling cables in a raceway you must limit the number in accordance with the percent fill limitations of Chapter 9, Table 1.

Author’s Comment: The proposal that was submitted for this change was not intended to required Class 2 or Class 3 cables to comply with the raceway fill limitations [ROP 16-36], but the language has that effect. But this is not important, because there is no physical way to install these cables anywhere near the 40% fill allowed in Chapter 9, Table 1 without destroying them.
