Here, I'll tell you what electrical grounding is, what it does, and why it's so important for the safety of every electrical circuit in your home. (familyhandyman.com)
What Is Electrical Grounding? (familyhandyman.com)
Tools, appliances, lights and electronics need specific voltages to operate correctly and safely, and system grounding stabilizes these voltages. (familyhandyman.com)
System grounding also limits voltage surges if lightning strikes your home or the surrounding area. (familyhandyman.com)

You'll also need to run a ground rod (I generally run 2 5/8" rods, 8' apart) and run a grounding wire (probably #4) to those rods. (doityourself.com)
The ground rod serves a completely different purpose than the grounding wire to the house. (doityourself.com)
But since you ran a grounding wire from the house, you absolutely must keep the grounding and neutral electrically isolated in the subpanel. (doityourself.com)
Otherwise you would have neutral current running on your grounding wire. (doityourself.com)
I've read previous posts regarding the grounding issues, and I've read about it elsewhere, but it's still not clear to me why, if, as John says, "Otherwise you would have neutral current running on your grounding wire", the same situation is not happening in the main panel, where the neutral and ground do not float. (doityourself.com)
Why isn't there "neutral current running on your grounding wire" in the main panel, and therefore, onto the metal frames of, say washers and dryers? (doityourself.com)
