I've been asked to get an opinion on what to do with the reduced size bare wire in NMC where in older houses we find it terminated by wrapping it around the cable clamp. Can we use that wire to connect it to the green screw on a replacement receptacle? The original receptacle was an ungrounded two wire receptacle. My opinion is that you can not use this a an equipment grounding conductor based on what it says at NEC Article 250.122(A). What say you guys?
