Charlie R Posted November 28, 2012 Report Share Posted November 28, 2012 I wrote this splice up but it was apparently done by a licensed electrician. Need some code ammunition for the gunfight that will be coming, can my fellow inspectors supply me the codes this does not meet?

Marc Posted November 28, 2012 Report Share Posted November 28, 2012 I don't have the 2011 NEC, just the 2008. Maryland uses the 2011. For what it's worth: 250.64 Grounding Electrode Conductor Installation© Continuous. Grounding electrode conductor(s) shall be installed in one continuous length without a splice or joint except as permitted in (1) and (2): (1) Splicing shall be permitted only by irreversible compression-type connectors listed as grounding and bonding equipment or by the exothermic welding process. (2) Sections of busbars shall be permitted to be connected together to form a grounding electrode conductor. Marc Quote Link to comment Share on other sites More sharing options...

Charlie R Posted November 28, 2012 Author Report Share Posted November 28, 2012 What about the size difference? Quote Link to comment Share on other sites More sharing options...
Marc Posted November 28, 2012 Report Share Posted November 28, 2012 What about the size difference? What size is the service? Marc Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted November 28, 2012 Report Share Posted November 28, 2012 What about the size difference? It's wrong because there shouldn't be a wire nut splice at all, because the wire nut isn't listed for those two sizes of wire, because the smaller wire is too small to perform as a GEC, and because the smaller wire is too small for the lug that it lands on. I find it hard to believe that a journeyman electrician did that work. Quote Link to comment Share on other sites More sharing options...
Charlie R Posted November 28, 2012 Author Report Share Posted November 28, 2012 Sad, but true. 200 amp service. Quote Link to comment Share on other sites More sharing options...
Marc Posted November 28, 2012 Report Share Posted November 28, 2012 Sad, but true. 200 amp service. #4 copper minimum size. Marc Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted November 28, 2012 Report Share Posted November 28, 2012 Sad, but true. 200 amp service. #4 copper minimum size. Marc That's true if it's going to a Ufer. If it's going to a water pipe or driven rod, then it only needs to be #6. 250.66(A) Quote Link to comment Share on other sites More sharing options...
