	Subject - Communication and power wiring jayd Is it against the code to run shielded communication wire in the same conduit as power wire even though the power wire and communication wire is serving the same dedicated equipment. JimmyDee They both have to be insulated for 600 volts. Jim blackrd As far as I know, com wire can never been installed in the same raceway as power. What is going to happen when a mettalic fault occurs in the raceway concerning the power conductors is what the concern would be. I believe there are limitations asto attaching communication wire to the exterior of electrical raceways. Alfred The code specifically states that communication wiring must be separated from electricial power by at least 3". No communication wiring shall be supported electrical conduits, strapping, etc. I also don't believe that the communication wiring is rated for 600 volts, only 300 volts.
