Stranded copper conductor in a ground lug

[mgarc]

If I twist a stranded conductor and install in a ground lug, will that be enough contact to get a proper bond or do all strands have to be against the set screw of the log?

If the lug is listed for stranded conductors in the size that you're using then all you should need to do is strip, insert and tighten.

I can't quite tell, are you describing a single stranded conductor with some of the strands cut off, or bent out of the lug? --Or-- are you describing a group of small gage conductors ( like #12 & #14 ) that are bundled together, twisted to be like a stranded conductor?

I think that he is wondering whether the twist has to be tight enough that each of the strands comes past the set screw. Or maybe that there needs to be compression on all of the strands that are in the lug (none hanging loose alongside the screw.)
In general if the lug is really rated for stranded wire of the size he is using the latter will apply.

I think allot of the OP questions was answered when the debate of finely stranded conductors issue was brought to light by UL, most building wiring using 7 to 19 strands don't have a problem with most lugs, but finely stranded conductors like DLO or welding cables require a lug that is listed for it.
