I have a client with an old apartment building being sold. The Home Inspector noted that the sub feeds from the service disconnect to the unit sub panels is 3 wire (two hots, one neutral). Was there a time when this was accepted by the NEC and if so do you know when the code was changed to require a 4 wire sub feed.
Thank You,
