Tracer Wire

About

• Video - [1]
• Tracer wire (blue) is required for potable water, sewer (green), gas (yellow).
• Tracer wire is not required for electrical. Warning tape is a good idea.
  • Mike Holt 2008 - warning ribbon is required for direct burial cables, whether in conduit or nott? [2]
  • This one says warning tape is not needed if you use conduit [3]
  • Practically speaking, warning tape is useful. Use 12" or more above the line. [4]. Point is: someone WILL dig your lines in the future. Things are modified all the time. If I had warning tape here, I would know where the first grid extension is. Now, I have to rely on a metal detector or other means.
• 6 colors all together - [5]
• Energized electrical is dangerous becuase it has no telltale signs, unlike gas or water [6]
• non-contact voltage tester - [7]

About

• Different techniques are used. Radar can find pipe, or induction-based emitter/sensor. Or the tracer wirewhere you connect to a wire. [13]
• There is jetting-vaccuum to dig in sensitive areas. Could do pressure washer as needed.

About Wire Quality

• It's the jacket: dog fence, which claims most reliability for burial - is 14AWG XHD [14]. They say that THHN (thermoplastic high heat nylon) is inferior to XHD - ot doesn't last underground
• The above indicates no difference between dog fence and tracer wire.

Tracer Kit

• Useful Amazon reviews - clip to ground and wire you want to trace. Then use the sensor. [15]
• Harbor Freight [16] - manual []
