a.   Plenum communications raceways
b.   Riser communications raceways
c.   Riser cable routing assemblies
d.   General-purpose communications raceways

Informational Note: See 830.26 for firestop requirements for floor penetrations.
(H)   Cable Trays. The following cables shall be permitted to be supported by cable trays:
(1)   Types BLP, BMR, BLR, BM, and BL
(2)   Types BLP, BLR, and BL installed in the following:
a.   Plenum communications raceways
b.   Riser communications raceways
c.   General-purpose communications raceways
(I)   Other Building Locations. The following cables shall be permitted to be installed in building locations other than those covered in 830.113(B) through(H):
(1)   Types BLP, BMR, BLR, BM, and BL
(2)   Types BLP, BMR, BLR, BM, BL, and BLX installed in raceways recognized in Chapter 3
(3)   Types BLP, BLR, and BL installed in the following:
a.   Plenum communications raceways
b.   Riser communications raceways
c.   Riser cable routing assemblies
d.   General-purpose communications raceways
e.   General-purpose cable routing assemblies
(4)   Type BLX less than 10 mm (3/8 in.) in diameter in one-and two-family dwellings
(5)   Types BMU and BLU entering the building from outside and run in rigid metal conduit (RMC) or intermediate metal conduit (IMC) where the conduit is connected by a bonding conductor or grounding electrode conductor in accordance with 830.100(B)
Informational Note: This provision limits the length of Type BLX cable to 15.2 m (50 ft), while 830.90(B) requires that the primary protector, or NIU with integral protection, be located as close as practicable to the point at which the cable enters the building. Therefore, in installations requiring a primary protector, or NIU with integral protection, Type BLX cable may not be permitted to extend 15.2 m (50 ft) into the building if it is practicable to place the primary protector closer than 15.2 m (50 ft) to the entrance point.
(6)   A maximum length of 15.2 m (50 ft), within the building, of Type BLX cable entering the building from outside and terminating at an NIU or a primary protection location."
