Description / Abstract:

This Standard applies to corrugated electrical nonmetallic tubing (ENT) and mechanically-attached fittings, for use in accordance with C22.1, Canadian Electrical Code, Part I (CEC), and NFPA 70, National Electrical Code (NEC). These requirements also apply to mechanically-attached fittings integral with an outlet box. 

Products covered by this Standard are intended for use: a) at a maximum continuous operating temperature of 75°C (167°F);

b) at a maximum ambient temperature of 50°C (122°F);

c) in attics provided that the ENT is installed no higher than 900 mm (3 ft) above the bottom of the ceiling joist, and the ENT material is rated minimum 60°C (140°F); and

d) underground (direct burial), in Canada only.

This Standard does not apply to fittings that are intended to be joined by solvent cement. Solvent-attached fittings are covered by UL 651 or CSA C22.2 No. 211.2. Solvent-attached fittings integral with an outlet or flush device box are covered by UL 514C or CAN/CSA-C22.2 No. 85.
