What kind of separation is required for excavating under 62KV electric lines? We don't want to have any arcing.

RE: Digging under High Tension Electric Lines
“Discussion: OSHA regulation 29 CFR 1926.600(a)(6) requires that boomed earth-moving vehicles comply with the requirements of 29 CFR 1926.550(a)(15) when working or being moved in the vicinity of power lines. This standard specifies that the minimum clearance between electric lines rated 50kV or below and any part of the boomed vehicle shall be 10 feet, unless the electrical lines have been "deenergized and visibly grounded" at the point of work. A 10-foot clearance would ensure that the vehicle would not contact and cut the overhead line, as in this incident, or become energized because of the contact. When a 10-foot clearance is difficult to maintain by visual means, a designated person can observe clearance between the lines and the equipment and give timely warning of imminent contact to the operator, or the local utility company should be contacted to deenergize the power line before work starts.”
While I could see some argument that this might be quite difficult to maintain in some situations; there is certainly no doubt one needs to maintain some reasonably safe distance and particularly from highly energized lines! (and I think the above contains at least some generally good thoughts/suggestions in this regard)

There is where your question should be.

The distance can also vary with the weather conditions too, specifically the humidity.

it's about halfway down (after the case descriptions)
50 to 200K 15 feet.
