Jerry Simon Posted February 24, 2020 Report Share Posted February 24, 2020 Is the cable running from the neutral lug up to the main service entrance cable raceway bushing area redundant panelboard bonding (in addition to the neutral bar bond screw) ? If not, what's the purpose of this cable? Quote Link to comment Share on other sites More sharing options...
Marc Posted February 24, 2020 Report Share Posted February 24, 2020 (edited) It's not redundant if there are concentric rings on that knockout. I'd have used the EGC bus for that, not sure why. It should be either green in color or bare copper. A cable is an assortment of conductors within one jacket.

plummen Posted September 7, 2020 Report Share Posted September 7, 2020 Yes that is a bonding bushing,should of been bare copper or some other color besides black though,they should've done a better job of marking that neutral also. Quote Link to comment Share on other sites More sharing options...
