Denray Posted June 27, 2013 Report Share Posted June 27, 2013 Checking out my new junkie continuity tester and it showed that this floating neutral bar was not floating when contacting the bar and the sub panel?

inspector57 Posted June 27, 2013 Report Share Posted June 27, 2013 How the heck and why would you test for that? If this is the service equipment it should be bonded, and if not, then it is bonded at the service equipment. How would a tester know the location of a proper bonding connection?

Denray Posted June 28, 2013 Author Report Share Posted June 28, 2013 Well this other sub panel ain't right. It looks like the neutral and equipment ground bar are tied together and the panel isn't bonded.

Marc Posted June 28, 2013 Report Share Posted June 28, 2013 I agree that they look connected. Marc Quote Link to comment Share on other sites More sharing options...

John Kogel Posted June 28, 2013 Report Share Posted June 28, 2013 Panel #1, looks correct. If you measured for continuity with a DMM, there would be some resistance in the feeder from the main panel. A fraction of an ohm, maybe. That would be correct. Panel #2 is simply wrong. There are bare ground conductors touching the panel box. So they are providing grounding that way, but bonding the neutrals to the sub as well, totally wrong. Quote Link to comment Share on other sites More sharing options...
Carson2006 Posted June 28, 2013 Report Share Posted June 28, 2013 Correct, somewhat. What you have are equipment grounding conductors attached to a neutral bus in this sub. (Which is wrong in this case) Both of those bus bars on each side are neutral conductor connection points and are tied together with an insulated bar behind the panelboard. What is needed is a grounding bus bar that is connected (bolted) to the metal enclosure with the equipment grounds (including the feeder equipment ground) stabbed there. Additionally that grounding bus bonds the metal enclosure as well. Easy fix. Hope this helps. Quote Link to comment Share on other sites More sharing options...
