605.1 Scope. This article covers electrical equipment, lighting accessories, and wiring systems used to connect, or contained within, or installed on relocatable wired partitions.

605.2 General. Wiring systems shall be identified as suitable for providing power for lighting accessories and appliances in wired partitions. These partitions shall not extend from floor to ceiling.

Exception: Where permitted by the authority having jurisdiction, these relocatable wired partitions shall be permitted to extend to, but shall not penetrate, the ceiling.

(A) Use. These assemblies shall be installed and used only as provided for by this article.

(B) Other Articles. Except as modified by the requirements of this article, all other articles of this Code shall apply.

(C) Hazardous (Classified) Locations. Where used in hazardous (classified) locations, these assemblies shall comply with Articles 500 through 517 in addition to this article.

605.3 Wireways. All conductors and connections shall be contained within wiring channels of metal or other material identified as suitable for the conditions of use. Wiring channels shall be free of projections or other conditions that may damage conductor insulation. Partition Interconnections. The electrical connection between partitions shall be a flexible assembly identi- fied for use with wired partitions or shall be permitted to be installed using flexible cord, provided all the following conditions are met:

(1) The cord is extra-hard usage type with 12 AWG or larger conductors, with an insulated equipment grounding conductor.

(2) The partitions are mechanically contiguous.

(3) The cord is not longer than necessary for maximum positioning of the partitions but is in no case to exceed 600 mm (2 ft).

(4) The cord is terminated at an attachment plug-and- cord connector with strain relief.

605.5 Lighting Accessories. Lighting equipment listed and identified for use with wired partitions shall comply with 605.5(A), (B), and (C).

(A) Support A means for secure attachment or support shall be provided.

(B) Connection. Where cord-and-plug connection is provided, the cord length shall be suitable for the intended application but shall not exceed 2.7 m (9 ft) in length. The cord shall not be smaller than 18 AWG, shall contain an equipment grounding conductor, and shall be of the hard usage type. Connection by other means shall be identified as suitable for the condition of use.

(C) Receptacle Outlet. Convenience receptacles shall not be permitted in lighting accessories.

605.6 Fixed-Type Partitions. Wired partitions that are fixed (secured to building surfaces) shall be permanently connected to the building electrical system by one of the wiring methods of Chapter 3. Multiwire branch circuits supplying power to the partition shall be provided with a means to disconnect simultaneously all ungrounded conductors at the panelboard where the branch circuit originates.

605.7 Freestanding-Type Partitions. Partitions of the freestanding type (not fixed) shall be permitted to be connected to the building electrical system by one of the wiring methods of Chapter 3. Multiwire branch circuits supplying power to permanently connected freestanding partitions shall be provided with a means to disconnect simultaneously all ungrounded conductors at the panelboard where the branch circuit originates.

605.8 Freestanding-Type Partitions, Cord-and-Plug- Connected. Individual partitions of the
