1 Scope
1.1 These requirements cover nonmetallic raceways and fittings. These products are for use as surfacewiring systems in accordance with the National Electrical Code@ (NEC) and Canadian Electrical Code(CEC),Part l.
1.2Raceways that are all nonmetallic and of any thickness are intended to enclose circuits operating atpotentials not exceeding 600 V between conductors.
1.3 Nonmetallic raceways with metal covers are intended to enclose circuits operating atpotentials in accordance with Table 1 or Table 1A.
1.4 These requirements do not cover surface metal raceways, cable trays, or wireways.
2 Definitions
2.1 For the purpose of this Standard, the following definitions apply:ACCESSORY – a part that may be added to a raceway system for a special purpose (for example,guards, hangers,retainers).
FITTING, RACEWAY – a part used to connect, change direction, or terminate a surface raceway (forexample, a transition coupler, an end cap, a corner, a tee, an adapter, or a box) or a system specificwiring device that completes the system.
FIXTURE BOX – a box used for the support of a lighting fixture, lampholder, or other equipmentintended for similar installation.
NONMETALLIC -a polymeric part.
SURFACE NONMETALLIC RACEWAY – a raceway for surface or suspension mounting with anonmetallic base and a nonmetallic or metal cover.
SURFACE RACEWAY SYSTEM – a system consisting of a surface raceway and associated fitingswhich may include wiring devices and accessories.
WIRING DEVICE – a part of an electrical system intended to carry, provide a means of connection to.
or provide control of electrical energy within a raceway system (for example, switches or receptacles).
