enclosure or on a listed primary protector.
FPN No. 1: Splice cases or terminal boxes, both metallic
and plastic types, are typically used as enclosures for
splicing or terminating telephone cables.
FPN No. 2: This exception limits the length of unlisted
outside plant cable to 15 m (50 ft), while Section
800.30(B) requires that the primary protector shall
be located as close as practicable to the point at
which the cable enters the building. Therefore,
in installations requiring a primary protector, the
outside plant cable may not be permitted to extend
15 m (50 ft) into the building if it is practicable to
place the primary protector closer than 15 m (50 ft)
to the entrance point.
Exception No. 4: Multipurpose cables shall be
considered as being suitable for the purpose and
shall be permitted to substitute for communications
cables as provided for in Section 800.53(G).
