AZGuy Posted March 25, 2007 Report Share Posted March 25, 2007 I'd always been perplexed by that 14-gauge wire wrapped loosely around gas mains where they exit the ground. It didn't make any sense because it's not bonded the the gas line with a clamp or anything. I just came across a book that explained what it's about. It turns out that when PVC gas lines (buried 18" below soil or 12" below concrete) are present, the wire isn't a bond wire, it's a TRACER wire. Duh, right? The portion of the gas run visible above ground is always metal, so I didn't know that nonmetallic gas lines are buried underground. Kind of gives a whole new meaning to "backyard barbeque" and "blue stake before you dig", doesn't it? Quote Link to comment Share on other sites More sharing options...
Mark P Posted March 25, 2007 Report Share Posted March 25, 2007 A tracer wire, as in in they need to locate the underground line? Quote Link to comment Share on other sites More sharing options...
AZGuy Posted March 25, 2007 Author Report Share Posted March 25, 2007 Yes. Tracer wires are used when a nonmetallic underground line can't be detected otherwise. Quote Link to comment Share on other sites More sharing options...
