Could someone help in finding a code refernce regarding conduit size. We at a Water Reclamation Facility have contractors doing installations at remote pumping stations. This one contractor has changed conduit size in the run. He has changed 1 inch to 3/4 in which he pulled a comm. cable Belden multi pair. I can use the table for conduit fill based on the specs from Belden and also probably use art.110-12 Mechanical Execution of Work. Any other suggestions?
