( _9 |5 |6 {9 R$ I/ ^3 ICommon mistake Question:

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.
