I have a 2 mile, under ground fiber run and I am adding a tracer for obvious reasons... I know that it should be grounded, but I can't find it referenced in the code, plus the customer doesn't want it grounded... Don't ask why, I justy need something to put infron of their face that will make them see things my way.... NEC 2005 reference plesase, and thanks in advance.

I agree that the function of the wire is to provide a "hit" for metal detectors and prevent cutting the circuit. But, as to grounding, if you do not ground it do you know its potential. Nope, you don't. If you take no action to determine the potential of the conductor, it may be at any random potential. So, ground it, but at one end only. Do not create a path, just insure the human safety of the wire by specifically grounding it.

I would not ground both ends as you may have some large induced currents. The fiber optics provides perfect isolatation between your two stations 2 miles apart. Why ruin that by running an electrical ground between the two? I agree with your customer. No ground.

The tracers that I have Sean is laid in the top of the ditch so a metal detector can find the ditch and prevent some one from cutting the cable.
