While replacing a panel, what I found which made this more time consuming and irritating were the grounds on most of the romexs had been twisted together and then put under one terminal screw, if anyone is out there still doing this and showing this method to an apprentice please stop, I don't want to be the one replacing the panel in the future and have to go thru the process of unbraiding ground wires this just irritates me so much %#@&*^)%$ . And the question is is this against code?
