Is there any reason any one can find that there needs to be 600v thhn wiring installed in conduit, (flexable)whithin a UL listed raceway within modular furniture. There are seperate raceways for the communications and the power. This job is located whithin the city of Chicago. I know in the past we have ran all 600v THHN wiring in superflex to the receptacles and task lighting in modular furniture. The furniture manufacturer claims it is not neccasary, but I don't want to take any chances with the inspectors. Any information would be helpfull.
