Galvanized Rigid Conduit (GRC) and Kwik-Couple® GRC
FEATURES & SPECIFICATIONS
Full Electrical System Protection
Manufactured from mild steel, Allied’s Rigid Conduit is highly
resistant to damage from impact yet ductile to facilitate bending.
The 3/4” taper NPT threads (ANSI B1.20.1) are full cut and hot
galvanized after cutting. Color-coded end cap thread protectors
keep the threads clean, sharp and also provide instant trade size
recognition. Even sizes are color-coded blue, 1/2 sizes black, and
1/4 sizes red.
Coatings
Hot-dip galvanized inside and out to provide galvanic corrosion
protection. Also topcoated with a compatible organic layer to
protect against white rust. The inside surface is evenly coated for
wire-pulling ease, even through multiple 90° bends.
EMI Shielding
Allied Rigid Steel Conduit is very effective in reducing the effects
of electromagnetic field levels for encased power distribution
circuits, shielding computers and other sensitive electronic
equipment from the effects of electromagnetic interference.
Visit www.alliedeg.com to obtain the GEMI (Grounding and
Electro-Magnetic Interference) software analysis program.
Codes & Standards Compliance
Standard Galvanized Rigid Steel Conduit produced by Allied
is precision manufactured for dependable, long-lasting value
and ultimate protection for electrical conductors. Covered
by article 344 of the National Electrical Code® (NEC), rigid
steel conduit is highly resistant to damage from impact. It
can be installed in all occupancies and locations, including
Class I Division 1 hazardous locations. Rigid steel conduit is
recognized as an equipment grounding conductor in Section
250.118 of the NEC. It is listed to Underwriters Laboratories
Safety Standard UL 6 and is manufactured to ANSI C80.1,
both of which have been adopted as Federal Specifications in
lieu of WWC 581.
Kwik-Couple Rigid steel conduit is listed to UL 6 and
UL 514B and is manufactured in accordance with
ANSI C80.1. Kwik-Couple Rigid Steel conduit is Listed
for Concrete-tight applications.
Installation of Rigid Metal Conduit shall be in accordance with the
National Electrical Code and UL General Information card #DYIX.
Master bundles conform to NEMA standard RN2.
Specification Data
To specify, Rigid Steel Conduit and Kwik-Couple Rigid Steel
Conduit include the following: Rigid Steel Conduit shall be
hot-dip galvanized and manufactured by Allied Tube & Conduit.
Threads shall be hot galvanized after cutting. Rigid steel
conduit shall be listed to UL Safety Standard 6 by a nationallyrecognized testing laboratory with follow up service. It shall be
manufactured in accordance with ANSI C80.1.
Note: Federal specification WW-C-581, Class 1,
Type A has been superseded by UL Standard 6,
which has been adopted by the federal government.
