1. Gxposcd: EMT. <br /> 2. Conccaled: EMT. <br /> 3. Damp or Wet Locations: RGS. <br /> 4. Boxcs and Enclosures: NEMA 250, Type 1, unless othenvisc indicated. <br /> 3.3 -RACEWAY AND CABLE INSTALLATION <br /> P.. Cnnceal race�vays and cables, unless oqicnvise indicated, within finished <br /> walls, ceilings, and [loors. <br /> B. Install raceways and cables at least G inches (I50 mm) away from parallel <br /> runs of tlucs and steam or hot-water pipcs. Locate horizontal raceway runs <br /> above water and steam piping. <br /> C. Usc temporary raceway caps to prevent forcign matter from entering. <br /> D. Make conduit Uends and offsets so ID is not rcduced. Keep legs of bends in <br /> thc same plane and straight legs of offsets parallcl, unless othenvise indicated. <br /> E. Use raceway and cable fittings compatible with raceways and caUles and <br /> suitable for use and localion. <br /> F. Install race�vays embedded in slabs in middle third of slab thickness where <br /> practical, and leave at least 1-inch (25-mm) concrete cover. <br /> I. Secure raceways to reinforcing rods to prevent sagging or shifting <br /> during concrete placcment. <br /> 2. Spacc raceways laterally lo prevent voids in concrete. <br /> 3. Install conduit larger Ihan 1-inch tr�de size (DN27) parallel to or at <br /> right angles to mam reinforcement. Where conduit is at right angles to <br /> reinforccment, place conduit close to slab support. <br /> 4. Transition from nonmetallic tuUing to Schedule 40 & 80 nonmetallic <br /> conduit, rigid steel conduit, or 1MC before rising above (loor. <br /> 5. Make bends in exposed parallel or banked runs from same ceuterline <br /> to make bends parallel. Use factory clbows onlv where elbows can bc <br /> installed parallel; othenvisc, providc field bcnds for exposcd parallel <br /> raceways. <br /> G. Install pull wires in empty raceways. Use No. l4 AWG zinc-coated steel or <br /> monofilament plastic linc witli not less than 200-Ib (90-kg) tensilc strenglh. <br /> Leavc at least 12 inchcs (300 mm) ofslack at cach cnd ofthc pull wirc. <br /> i <br /> H. Set boxes level and trim aftcr installation to fit (lush to finished surface. <br /> 3.4 - WIRING MGTIiODS I�OR PO�VTR, L[GATING,AND CON7'ROI.CIRCUITS <br /> A.
