To protect those working near overhead power lines from accidental contact, the State of California has enacted the following regulations to establish safe operating practices near energized overhead lines. These regulations are generally described in this pamphlet. Please refer to the actual regulations and statutes for the complete requirements.
California Penal Code, Section 385 This statute makes it a misdemeanor for anyone to be within six feet of an overhead electric line having a voltage in excess of 750 volts, or to move or operate any equipment, tools, machines or structure within six feet of such a line. The only exemptions are for those persons authorized by the owner of the electric line. California Code of Regulations, Title 8, Section 2946 This regulation stipulates that no person, firm or corporation shall require or permit any employee to perform any function in proximity to energized high voltage electric lines, or engage in any construction, repair or other activity, or erect, install, operate or store any tools, machinery, equipment, materials, etc. in proximity to energized high voltage electric lines unless danger from accidental contact with the high voltage line has been effectively guarded against. This regulation is
enforced by the California Division of Occupational Safety and Health (Cal/OSHA). Specifically, except where overhead electrical lines have been de-energized and visibly grounded, the operation, erection, handling, or transportation of tools, machinery, materials, structures, scaffolds, or the moving of any house or other building, or any other activity where any parts of the above or any part of an employee’s body will come closer than the minimum clearances from energized overhead lines as set forth in Table 1 below is prohibited.
