The superintendent on the job is differing from my opinion on the "allowability" of MC cable in the walls I will paste the job specs below. I am not reading that MC cable is not allowed in the walls for receps etc. I believe he is reading into the Raceway section of the job specs about emt inside interior wall. I believe that since that it under the "Raceway" section of the specs it is only dealing with raceways themselves and not wiring methods, and it is my understanding that MC cable is not a raceway. Below are the pertinent specs. There is also the "shall be primarily used as whips", but all mc restricted jobs I have ran listed it as ONLY or under the "do not use". What is your professional opinions on this?
