Do you splice all your EGCs together?

Let's get a couple things straight here. For one, the abbreviation I assume we're talking about is Grounding Electrode Conductor, which is GEC, not EGC. And if that's what we're talking about, we're a little off track here talking about outlet boxes. I think your confusing GEC with equipment ground (EG). Big difference, both both provide (ideally);a low resistance path to ground. And they should be joined at each termination for sake of maintaining equipotential among non-current-carrying metal parts.

Did you even read the first post in the thread? We're talking about the EGCs.
