We have a project that will be re-using three 4 inch rigid steel conduits for a new 2000A 480/277V feeder. Two new conduits will be added for a total of five conduits. The new feeder will consist of 5 sets of 600KCMIL THHN conductors with 250KCMIL THHN equipment ground conductors. Can the two additional conduits be steel EMT? Is steel EMT similar enough to steel rigid conduit to be acceptable and not a violation of NEC 310.10 (G)(2)?
