Floor penetrations requiring Type FPLR shall contain only cables suitable for riser or plenum use. Type FPLR-CI cable shall be permitted to be installed to provide a

2-hour circuit integrity rated cable.

(2) Other cables shall be installed in metal raceways or located in a fireproof shaft having firestops at each floor.

(3) Type FPL cable shall be permitted in one- and two- family dwellings.

FPN: See 300.21 for firestop requirements for floor penetrations.
(C) Other Wiring Within Buildings. Cables installed in building locations other than those covered in
760.154(A) or (B) shall be as described in either (C)(1), (C)(2), (C)(3), or (C)(4). Type FPL-CI cable shall be permitted to be in stalled as described in either (C)(1), (C)(2), (C)(3), or (C)(4) to provide a 2-hour circuit integrity rated cable.

(1) General. Type FPL shall be permitted.

(2) In Raceways. Cables shall be permitted to be installed in raceways.

(3) Nonconcealed Spaces. Cables specified in Chapter 3 and meeting the requirements of 760.179(A) and (B) shall be permitted to be installed in nonconcealed spaces where the exposed length of cable does not exceed 3 m (10 ft).

(4) Portable Fire Alarm System. A portable fire alarm system provided to protect a stage or set when not in use shall be permitted to use wiring methods in accordance with 530.12.

(D) Fire Alarm Cable Substitutions. The substitutions for fire alarm cables listed in Table 760.154(D) and illus trated in Figure 760.154(D) shall be permitted. Where substitute cables are installed, the wiring requirements of Article 760, Parts I and III, shall apply.
