O.K. guys, I am going to pick your brains for a second or two. Back in 93 or 96 code cycle, Elect. contractor Mag. put out a booklet of code changes,(which they still do), about the ground screw and bonding screw in panel boards had to be green and of the threaded type, and it could not be a sheet metal or tek screw. Anyone else recall this? I cannot find My 2002 handbook to look it up cuz I moved, but my wife has seen it. Just my .02 cents!
