I was looking at my service panel and noticed I don’t see any wires leading to the ground. Is it possible there is no ground or maybe the ground comes from my service? I have four wires coming in. I suppose there are 2 hot, 1 neutral and so is the 4 one ground? This is an older home and I am looking to upgrade my circuit breaker and I want to ensure I have everything in place before I talk to an electrician. Thank You![enter image description here]1

  • Are you looking for your grounding electrode system, or your equipment grounding system? Because it looks like you have a four-wire feed from your meter-main to your indoor disconnect (which is good!) but without more photos, we can't see beyond that... – ThreePhaseEel May 13 '20 at 11:49
  • Also, it appears you've created two accounts, you probably should get them merged so that you can contribute fully to this site – ThreePhaseEel May 13 '20 at 11:58
  • One more thing: where do the red and black wires extending out the right of the upper photo run to? – ThreePhaseEel May 13 '20 at 11:59
  • I really can't quite figure out what the pictures show, but if you have four wires coming from the meter then it is likely the grounding electrode is connected in the meter. This wasn't uncommon to do in the past, but now is considered unacceptable by most jurisdictions since the meter should only be removed by the utility, and you can't inspect the connections without removing the meter. ***If you do have four wire coming from the meter then the ground and neutral should be separate after the meter. – NoSparksPlease May 13 '20 at 15:23

    You have an unusual setup with a 200 amp disconnect feeding another 200 amp disconnect, I see a utility ground at the meter but no equipment ground (local driven rod, pipe or plate electrode connected with #6 or a ufer ground connected with #4 copper being the most common types) prior to the 99 code what you have would need the local ground. But having multiple small wires on that 200 amp breaker have never been ok or another code violation is multiple neutral white wires under 1 lug. The inside panel should feed or be replaced with a new panel having appropriately sized breakers for the wires – Ed Beal May 13 '20 at 17:35
