Dave Batzdorf Posted January 13, 2010 Share Posted January 13, 2010 yes, the same thickness. We mostly use 18-ga. Link to comment Share on other sites More sharing options...
shiner Posted January 13, 2010 Share Posted January 13, 2010 Yes, the copper is the same, but the outer jacket is thicker. I find that rabbits in my area do not damage the spt2 like they do the spt1. Additionally, I have a brick home. The rubbing around corners is another reason I went for the SPT2 to reduce the likelyhood of damaging the cords during set up and tear down from year to year.this is one of those personal preference things.Paul from CDI sells what he calls spt3. This is the same as spt1 in thickness of jacket, but there is an additional UV inhibitor in the jacket to in theory make it last longer in the sun.

stanward Posted January 13, 2010 Share Posted January 13, 2010 Similar reason why I run the SPT2 wire, I have it lying on the ground, which is composed of gravel and/or cinder, and sometimes I do step on them when walking thru the yard. Link to comment Share on other sites More sharing options...
