Re: Conduit Question from "Another Forum"
"I am pretty sure that flex conduit in the walls is a big no-no per the NEC"
While the City of Los Angeles still had its own electric code (it FINALLY adopted the NEC in about 1975), all wiring of whatever kind had to be in conduit.
That conduit could be metal flex (steel was preferred, but aluminum was also accepted by some inspectors), EMT or rigid (rigid was preferred for services).
The continuous metal conduit, or the segmented metal conduit if a combination of EMT/rigid and flex was used, using approved transition connectors, was the groundING system.
Indeed, in Chicago, Greenfield, which is a manufactured flex with integral conductors, is still required for all interior wiring.
NM has been allowed in Los Angeles, for residences only, with the 1975 change from the LA Electric Code to the NEC.
