Maine Revised Statutes Title 35-A. Public Utilities § 755. Clearance reduced

If the overhead high-voltage line is covered with a mechanical barrier, in accordance with section 758, the required clearance under section 754, subsections 1 and 2 may be reduced to the designed working dimensions of the mechanical barrier. If the line is de-energized and grounded, in accordance with section 758, subsection 5, the required clearance under section 754, subsections 1 and 2 is reduced from 10 feet to 2 feet. Under no circumstances may the overhead high-voltage line or its covering be contacted. If the overhead high-voltage lines are temporarily raised or moved to accommodate the expected work or other activity, without also being insulated or de-energized and grounded, the required clearance under section 754, subsections 1 and 2 may not be reduced.
