Sub Panel installed 1979Report
Please briefly explain why you feel this question should be reported.
I have recently read that sub panels installed after 2011 need to have separate ground bar and neutral bar. I have included a picture for review of the panel installed in my basement in 1979. Can someone explain what is right or wrong with my sub panel wiring? You can see what appear to be the incoming bare wire(ground circled in green) and the bus bar (circled in red). The bus bar contains both neutral and ground as does the main panel which I have also read is ok on main panel only.
