I asked around a little about what folks thought would happen if some other sparky showed up to set his panel and the 4ga GEC was missing.
Several alternate grounding methods were suggested but then I told them about the Mass law requiring the sparky to dig out some steel in the footer (probably on his dime).
The unanamous answer, he would stuff a piece of wire in the wall and swear that was the same wire the inspector signed off if he thought he could get away with it. Of course everyone said they would always do the right thing themselves. [Linked Image]
