1.1 These requirements cover FITTINGS for use with cable and conduit intended for installation in
accordance with the National Electrical Code, ANSI/NFPA 70, the Canadian Electrical Code (CEC), Part
I, CSA C22.1, and the Standard for Electrical Installations, NOM-001-SEDE.
1.2 These requirements cover CONDUIT LOCKNUTS, conduit BUSHINGS, metal stud BUSHINGS, CONDUIT BODIES, and
entrance ELBOWS; FITTINGS for electrical metallic tubing, flexible metal conduit, intermediate metal conduit,
liquid-tight flexible conduit, rigid metal conduit, and SERVICE-ENTRANCE HEADS; FITTINGS for armored cable,
metal-clad cable, aluminum-sheathed cable, mineral-insulated cable, nonmetallic-sheathed cable,
service-entrance cable, and tray cable, and submersible FITTINGS; FITTINGS for flexible cord, flexible
nonmetallic and metallic tubing, INSULATING BUSHINGS, grips, reducing washers, and NIPPLES.
Note: In Canada, fittings for metal-clad (MC) cable, intermediate metal conduit (IMC), flexible metallic tubing,
flexible nonmetallic tubing, and CONDUIT BODIES are not recognized. CONDUIT BODIES are considered FITTINGS.
Note: In Canada, armored cable includes Type TECK cable.
Note: In Mexico and the United States, requirements for submersible FITTINGS are provided in NMX-J-235/1-ANCE,
NMX-J-235/2-ANCE, or UL 50.
Note: In Mexico, intermediate metal conduit is designated as semi-heavy metal conduit.
1.3 The requirements in Clause 5.7 cover CONDUIT BODIES for rigid polyvinyl chloride (PVC) conduit. These
products are intended to be used with both heavy-wall and thin-wall rigid PVC conduit, ELBOWS, and other
bends. The products covered by these requirements are intended to be joined to rigid polyvinyl chloride
(PVC) conduit and rigid PVC ELBOWS and other bends in the field by means of a cement that is, or contains,
a solvent for polyvinyl chloride.
1.4 These requirements do not cover FITTINGS intended for use in hazardous locations as defined in the
National Electrical Code, ANSI/NFPA 70, the Canadian Electrical Code (CEC), Part I, CSA C22.1, and the
Standard for Electrical Installations, NOM-001-SEDE.
1.5 These requirements do not cover FITTINGS intended for use with surface raceway systems.
1.6 These requirements do not cover conduit NIPPLES, threaded ELBOWS, and threaded COUPLINGS intended
for use with rigid metal conduit, intermediate metal conduit, or electrical metallic tubing.
