Mike Lamb Posted February 19, 2013 Report Share Posted February 19, 2013 I'm just double checking since my electrical expertise is second best. The main disconnect is outside at the meter about 30 feet away from this panel. So this panel in the garage is really a subpanel. It looks like the grounding electrode is not isolated from the neutrals. This is wrong? Correct? The wiring looks so sweet that it doesn't seem likely that the electrician would screw this up.

John Dirks Jr Posted February 19, 2013 Report Share Posted February 19, 2013 That might be a neutral that was added to make what once was a 2 wire with ground 240 dedicated into a 3 wire with ground 120/240. Could you see where it went? I don't understand why it is sheathed in black insulation though. If it were a ground or a neutral, I think it should either be bare or have a white sheathing. I'd be confused looking at that too. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted February 19, 2013 Report Share Posted February 19, 2013 If that black is a grounding conductor, it appears to be an error, no matter how neat and tidy the work is. Quote Link to comment Share on other sites More sharing options...

I presume that this panel's feeder includes an equipment grounding conductor? And that there's an equipment grounding terminal bar? If so then, yes, the grounding electrode conductor should land on the grounding terminal bar and not the neutral terminal bar. (250.32) I'm not aware of any requirement to identify the grounding electrode conductor with a particular color. It doesn't need to be green.

kurt Posted February 19, 2013 Report Share Posted February 19, 2013 Local 134 doesn't necessarily agree with us. It can get complicated. Depending on who you talk to, you will get differing opinions. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted February 19, 2013 Report Share Posted February 19, 2013 Local 134 doesn't necessarily agree with us. It can get complicated. Just saying. This is a pretty basic issue. I'd think that the brethren would be onboard with it. I'm not convinced that that panel was wired by a pro anyway. Quote Link to comment Share on other sites More sharing options...
