Common mistake Question:
% j: J- ^+ g" j/ t7 {5 K6 n! B7 ]$ V
) ~  S! E! L9 X/ T: C6 }What would you do? Lets say you are adding a circuit into a sub-panel, and you see no ground bar. The grounds and neutrals of about twenty 12-2s go to the neutral bars and the box remains ungrounded. Your sub-feed is four wire(A,B,N,G) and the last forgetful sparky left that bar that can bond the box to the neutral bar. please vote.
