In regards to this article; 695.6 a through b. The NEC discusses 2 types of conductors, circuits and service. I am installing an ATS within sight to an existing FP controller and motor. The motor is routed correctly under the floor and is of no concern. Both the normal and emergency circuits enter the ATS via normal install while adhering to the Exception. The question resides in the conduit that feeds the controller from the ATS. Does this rigid or IMC conduit need to be encased in concrete or can I use a 2 hour fire rated wire and install as normal overhead?
