The following combinations are acceptable in <br />conduit, or cable harnesses. Additional acceptable combinations may be indicated <br />on the Contract Drawings. <br />a.Types A-1, C-1, and M-1. <br />b.Types A-2, C-l, C-2, and M-l, runs less than twenty (20) feet. <br />c.Types A-2, C-1, and M-1. <br />d.Types A-3, C-1, C-2, and M-1. <br />e.Types A-2, V-1, and V-3. <br />f.Types V-1, V-2, V-3, and C-1. <br />g.Types M-2 and C-3. <br />3.4 WIRE AND CABLE INSTALLATION <br />A.Provide permanent identification of run destination at all raceway terminations. <br />B.All wire and cable shall be continuous and splice-free for the entire length of run between <br />designated connections or terminations. <br />C.All shielded cables shall be insulated. Do not permit shields to contact conduit, raceway, <br />boxes, panels or equipment enclosures. <br />D.Within buildings, make splices only in designated terminal cabinets and/or on designated <br />equipment backboards. Outside buildings, make splices only in designated manholes and/or <br />handholes. Protect splices outside of buildings with splicing kits equivalent to Scotchcast Re- <br />enterable. Make splices only with connectors or terminal devices specified herein. <br />Document all splices on Record Drawings. <br />E.Verify that all raceway has been de-burred and properly joined, coupled, and terminated prior <br />to installation of cables. Verify that all raceway is clear of foreign matter and substances prior <br />to installation of wire or cable. <br />F.Inspect all conduit bends to verify proper radius. Comply with Code for minimum permissible <br />radius and maximum permissible deformation.
