Jerry Lozier Posted June 2, 2013 Report Posted June 2, 2013 Main panel is an outside pedestal: looks good 4 wire service coming to SUBPANEL in house basement Neutrals and grounds are on separate bars as they should be. Green (ground) cable from main panel goes to ground bar in sub ***Solid Copper from ground rod attaches to neutral bar. (That don't seem right as doesn't the ground usually attach to the ground side with the cable from the main panel so the neutrals stay isolated) I'm thinking the only cable attached to neutral side should be the neutral cable from the main panel.

Marc Posted June 2, 2013 Report Posted June 2, 2013 The GEC should connect to the neutral at a point between the load end of the service drop or service lateral to and including the teminal or bus to which the grounded service conductor is connected at the service disconnecting means. 250.24 (A) (1) It should not bond at a sub-panel.

Jim Katen Posted June 2, 2013 Report Posted June 2, 2013 I don't fully understand what you've got there. When you say that the service panel at the pedestal "looks good" does that mean that it has a proper grounding electrode system? If so, then there's nothing wrong with having a grounding electrode connected to the sub panel, but it should, of course, be connected to the grounding terminal bar.

Yes main panel (first disconnect) and meter base are remote and have proper ground. Remote distribution (sub) panel pictured in my post above, never seen one with the #6 copper GEC connected to neutral bar rather than ground bar. 6 year old install with L&I stickers approval of installation, just wanted to know if they knew something I didn't... So wanting to confirm it is incorrect as currently installed.. Click to Enlarge 95.65 KB
Jim Katen Posted June 2, 2013 Report Posted June 2, 2013 It's incorrrect as currently installed. The grounding electrode for the house should be connected to the sub panel's grounding terminal bar.
Rob Amaral Posted June 2, 2013 Report Posted June 2, 2013 This discussion with some experts is why the guy messed this up in the first place.. It's easy to mess this up 'Mentally'.. The installer did not understand 'the why' of the directives in regards to this.. If you don't know 'why'.. .you can easily mix this up.. Which is why I tell folks this every single week.. 'These guys are licensed, but they don't know 'why' they are supposed to do this stuff sometimes.. "
Jerry Lozier Posted June 3, 2013 Author Report Posted June 3, 2013 Thank you gentlemen, as I suspected.
