TYPE NMHTTYPE NM
A general-purpose, nonmetallic liquidtight conduit offers
excellent protection to wiring from abrasion, sunlight, mild
acids, alkaline and oils. It is often used for air conditioning
hookups and other outdoor applications.
Nonmetallic
CONSTRUCTION: Type NM is a helically wound integral Type
B construction. It contains a spiral of rigid PVC reinforcement
imbedded within the PVC wall.
APPLICATION: Type NM is intended for installation in
accordance with Article 356 of the NEC (ANSI / NFPA-70) for
Flexible Liquidtight Nonmetallic Conduit (LFNC-B or FNMC-B).
• For containment of 600 volt and lower potential circuits.
• Listed and marked for outdoor use.
• Listed and marked for direct burial and in poured concrete.
• Installations in hazardous (classified) locations:
- Class I Div. 2 Article 501
- Class II Div. 1 & 2 Article 502
- Class III Div. 1 & 2 Article 503
• Electric signs and outdoor lighting over 1,000 volts. Article
600.32(A).
• Wiring methods for pools and spas. Article 680.

Electrical Standard for Industrial Machinery NFPA-79.
Listed File #E79308. Conforms to Underwriters Laboratories
Standard ANSI/UL 1660 type B.
RoHS and WEEE Compliant.
This version of Type NM is designed to withstand hightemperature environments. NMHT can be used to contain
conductors having insulation materials with higher
temperature ratings.
CONSTRUCTION: Type NMHT is made in the same manner as
Type NM. It contains a rigid PVC spiral reinforcement within the
wall of the conduit.
