The 2002 NEC includes a rule in 300.21 that covers the subject of the "spread of fire or products of combustion for most systems in many occupancies."

This rule also applies to the installation here because of the following rule.

770.3 Locations and Other Articles. Circuits and equipment shall comply with

770.3(A) and (B). Only those sections of Article 300 referenced in this article shall apply to optical fiber cables and raceways.

(A) Spread of Fire or Products of Combustion. The requirements of 300.21 for electrical installations shall also apply to installations of optical fiber cables and raceways.

The accessible portion of abandoned optical fiber cables shall not be permitted to remain.

Are most installers aware of this requirement?
