Question:
Greetings Code Question Staff,
Can rigid metallic conduit be installed without a wire-type equipment grounding conductor installed with the circuit conductors in the conduit? We have a project specification that requires this. The project specs also indicate that compliance with the latest edition of the NEC is also necessary. We appreciate your insight.

Answer:
Hello James, thanks for participating. The simple answer is yes. Section 344.60 and Section 250.118(2) each indicate that rigid metal conduit is suitable as an equipment grounding conductor. Now if you have a project specification that requires something over and above the minimum rules in the NEC, then installing the wire-type EGC becomes required by specification.
