** NOTE TO SPECIFIER ** Wheatland Galvanized Rigid Conduit can be installed indoors or outdoors, in dry or wet locations, exposed or concealed, in all kinds of atmospheric conditions, and in hazardous locations when in accordance with NEC 2005 Article 344. It provides excellent mechanical protection for the conductors while reducing Electro-Magnetic Field (EMF) exposure and shielding against Electro-Magnetic Interference (EMI). RMC is recognized by NEC 2005 section 250.118(2) as an equipment grounding conductor. Edit 2.2 through 2.5 as required by project. Associated Fittings are nipples, elbows and couplings that are covered by the applicable raceway standard, rather than UL 514B or ANSI/NEMA FB1.
 
          2.2RIGID METAL CONDUIT AND TUBING
 
          A.Rigid Metal (Steel) Conduit (RMC) that meets the requirements of UL 6 Electrical Rigid Metal Conduit - Steel, ANSI C80.1 - Electrical Rigid Steel Conduit (ERSC), and ANSI/NFPA 70 National Electrical Code, Article 344.

          3.2INSTALLATION
 
          A.Install raceways and boxes according to NECA 1 Standard Practices for Good Workmanship in Electrical Construction, the NEC, and requirements in this Section.
 
          B.Raceway routing is shown on the Drawings in approximate locations unless dimensioned. Coordinate routing with structure and with work of other trades. Route as required for a complete wiring system.
 
          C.Minimum Conduit and EMT Size: Trade size 1/2.
          ** NOTE TO SPECIFIER ** Insert values suitable for project. Delete paragraph if distances shown on the Drawings.
 
          D.Keep raceways at least ___ inches away from parallel runs and ___ inches when crossing of flues and steam or hot water pipes. Install horizontal raceway runs above water and steam piping.
 
          E.Complete conduit raceways between termination points prior to the installation of conductors.
 
          F.Limits bends between pull points to no more than 4 bends totaling 360 degrees.
 
          G.Make bends and offsets so inside diameter of the conduit or tubing will not be effectively reduced. Keep legs of bends in the same plane and keep straight legs of offsets parallel, unless otherwise indicated.
 
          H.Secure and support raceways as required by the NEC and Section 16070.
 
          I.Metal raceways are not to be supported, terminated, or connected by welding to the raceway.
 
          J.Do not support conduit with wire or perforated pipe straps. Remove wires used for temporary support.
 
          K.Install temporary closures or caps during construction to conduit and the threads and prevent foreign matter from entering raceways. All conduit and tubing shall be swabbed and cleaned before pulling wire or cables.
 
          L.Use conduit hubs to fasten conduit to boxes in damp and wet locations.
 
          M.Conceal conduit and EMT within finished walls, ceilings, and floors, unless otherwise indicated. Install concealed raceways with a minimum of bends in the shortest practical distance, considering type of building construction and obstructions, unless otherwise indicated.
 
          N.Install grounding bushings at the following locations:
          1.At every entry to enclosures on metallic conduits containing circuits rated 100 amperes and higher.
          2.On metallic conduits entering enclosures through concentric, eccentric or oversize knockouts.
          3.On metallic conduits that terminate to a metallic enclosure without effective electrical connection such as locknuts or threaded bushings.
 
          O.Raceways Embedded in Slabs: Install in middle 1/3 of slab thickness where practical and leave at least 2 inches (50 mm) of concrete cover:
          1.Secure raceways to reinforcing rods to prevent sagging or shifting during concrete placement.
          2.Space raceways laterally to prevent voids in concrete.
          3.Transition to PVC tape-wrapped rigid steel conduit or PVC tape-wrapped intermediate metal conduit before rising above the floor.
          4.Use coupling and connector approved for the application.
 
          P.Install expansion fittings where embedded or surface mounted conduits cross building expansion joints.
 
          Q.Stub-up Connections: Extend conduits through concrete floor for connection to freestanding equipment. Install with an adjustable top or coupling threaded inside for plugs set flush with finished floor. Extend conductors to equipment with rigid steel conduit; FMC may be used 6 inches above the floor. Install screwdriver-operated, threaded plugs flush with floor for future equipment connections.
 
          R.Protect stub-ups from damage where conduits rise through floor slabs. Arrange so curved portions of bends are not visible above the finished slab.
 
          S.Install exposed conduit parallel to or at right angles to nearby surfaces or structural members and follow surface contours as much as practical.
          1.Run parallel or banked raceways together on common supports where practical.
          2.Make bends in parallel or banked runs from same center line to make bends parallel. Use factory elbows only where elbows can be installed parallel; otherwise, provide field bends for parallel raceways.
 
          T.Raceway termination points and box locations shown on the Drawings are in approximate locations unless dimensioned. Verify locations before rough-in.
 
          U.Join raceways with fittings designed and approved for that purpose and make joints wrench tight. Tighten set screws of threadless fittings with suitable tools.
 
          V.Terminations:
          1.Where raceways are terminated with locknuts and bushings, align raceways to enter squarely and install locknuts with dished part against box. Use two locknuts, one inside and one outside box.
          2.Where raceways are terminated with threaded hubs, screw raceways or fittings tightly into hub so end bears against wire protection shoulder. Where chase nipples are used, align raceways so coupling is square to box; tighten chase nipple so no threads are exposed.
          3.Install insulating bushings or connectors with an insulated throat to protect conductors or cables at conduit terminations.
 
          W.Install pull wires in empty raceways. Use polypropylene or monofilament plastic line with not less than 200-lb tensile strength. Leave at least 12 inches of slack at each end of pull wire.
 
          X.Install conduit sealing fittings at suitable, approved, and accessible locations and fill them with UL-listed sealing compound. For concealed raceways, install each fitting in a flush steel box with a blank cover plate having a finish similar to that of adjacent plates or surfaces.
          1.Install raceway sealing fittings where conduits pass from warm to cold locations, such as boundaries of refrigerated spaces and air-conditioned spaces, between areas where air pressure differential must be maintained, and where otherwise required by the NEC.
 
          Y.Avoid moisture traps in conduit system; provide junction boxes with drain fitting at low points in conduit system.
 
          3.3FIRESTOP INSTALLATION
 
          A.Install fire and smoke stop material at single electrical conduit penetrations through core-drilled openings in fire-rated concrete walls and floors. Install following manufacturer's instructions to restore original fire rating.

          C.Request inspection of firestopping installations by the Authority Having Jurisdiction both before and after installation of firestopping materials.
 
          3.4PROTECTION
 
          A.Provide final protection and maintain conditions that ensure coatings and finishes are without damage or deterioration at time of Substantial Completion.
