Jerry Lozier Posted May 26, 2010 Report Share Posted May 26, 2010 Never seen grounded conductors done this way... I call them out when there are 2 or more or combined with a ground under one lug on bar. However there is no way one could come loose and both are same gauge 12awg... any problem here?? Yes there are 2 grounds at lug above with different gauges, probably not best practice. Download Attachment: P5250051.JPG 82.18 KB Quote Link to comment Share on other sites More sharing options...

Twisted or not, the lugs aren't listed to hold more than one neutral. The twisting will make it slightly more difficult to isolate a circuit during furture trouble shooting. Nothing about the twisting method is "better" than simply sticking the two wires under the lug. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Jim Katen Posted May 26, 2010 Report Share Posted May 26, 2010 . . . so that brings up multiple grounds under lug rated for one wire, or is lug rated only for (no more than one neutral because it cares current?) The lugs will typically be rated for two or three grounding wires (depending on the size of the wires), but only one "grounded" (neutral) wire because, as you say, it carries current. The grounding wires only have to carry current for a split second. You'll find the lugs' limitations printed on the panel schematic. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
