OSHA clearly states that it is prohibited to work less then 10 feet away from electrical lines.
1910.333(c)(3)(i)(A)
When an unqualified person is working in an elevated position near overhead lines, the location shall be such that the person and the longest conductive object he or she may contact cannot come closer to any unguarded, energized overhead line than the following distances:
1910.333(c)(3)(i)(A)(1)
For voltages to ground 50kV or below - 10 ft. (305 cm);
1910.333(c)(3)(i)(A)(2)
For voltages to ground over 50kV - 10 ft. (305 cm) plus 4 in. (10 cm) for every 10kV over 50kV.
