A method for maintaining a section of an electrified, three-phase power conductor line, wherein the three phases (A, B and C) are in substantially a common plane, in an ordered sequence and strung between a set of support structures, wherein at least two equal potential zones are employed in electrical communication with at least one of said three phases, the method comprising steps of: a) positioning at least one auxiliary support substantially adjacent the set of support structures so as to support an electrified first section of a first phase-needing-maintenance (102), the at least one auxiliary support supporting at least two auxiliary dead end supports (113', 113"), and said electrified first section of said first phase-needing-maintenance having opposite first and second dead end junctures (110', 110") at opposite ends thereof, b) moving said first section of said first phase-needing-maintenance so as to be strung upon said at least one auxiliary support and said at least two auxiliary dead end supports, wherein said first and second dead end junctures are supported by said at least two auxiliary dead end supports, c) stringing a first new phase conductor (114, D phase) between the set of support structures where the section of said first phase-needing-maintenance was moved from, d) electrically connecting a first conductor of a first transfer bus and a first conductor of a second transfer bus (118") to said first new phase conductor, e) electrically connecting a second conductor of said first transfer bus and a second conductor of said second transfer bus to an electrified second section of a second phase-needing-maintenance (102) that is proximate to said first phase-needing-maintenance, wherein said electrified second section comprises a third dead end juncture and a fourth dead end juncture (110") at opposite ends thereof, characterised by: f) electrically connecting said first transfer bus so as to bring said first new phase conductor to an electrical potential that is equal to said second phase-needing maintenance and establishing a first electrically parallel connection between said first new phase conductor and said second phase-needing-maintenance, g) electrically connecting said first new phase conductor to a first segment of said second phase-needing-maintenance on opposite sides of said third dead end juncture, and electrically connecting said first new phase conductor to a second segment of said second phase-needing-maintenance on opposite sides of said fourth dead end juncture, so as to complete a second electrically parallel connection between said first new phase conductor and said second phase-needing-maintenance, h) electrically disconnecting said second section of said second phase-needing-maintenance so as to isolate said second section of said second phase-needing-maintenance from said first and second segments of said second phase-needing-maintenance and said first new phase conductor, and i) maintaining said second section of said second phase-needing-maintenance a) positioning at least one auxiliary support substantially adjacent the set of support structures so as to support an electrified first section of a first phase-needing-maintenance (102), the at least one auxiliary support supporting at least two auxiliary dead end supports (113', 113"), and said electrified first section of said first phase-needing-maintenance having opposite first and second dead end junctures (110', 110") at opposite ends thereof, b) moving said first section of said first phase-needing-maintenance so as to be strung upon said at least one auxiliary support and said at least two auxiliary dead end supports, wherein said first and second dead end junctures are supported by said at least two auxiliary dead end supports, c) stringing a first new phase conductor (114, D phase) between the set of support structures where the section of said first phase-needing-maintenance was moved from, d) electrically connecting a first conductor of a first transfer bus and a first conductor of a second transfer bus (118") to said first new phase conductor, e) electrically connecting a second conductor of said first transfer bus and a second conductor of said second transfer bus to an electrified second section of a second phase-needing-maintenance (102) that is proximate to said first phase-needing-maintenance, wherein said electrified second section comprises a third dead end juncture and a fourth dead end juncture (110") at opposite ends thereof, characterised by: f) electrically connecting said first transfer bus so as to bring said first new phase conductor to an electrical potential that is equal to said second phase-needing maintenance and establishing a first electrically parallel connection between said first new phase conductor and said second phase-needing-maintenance, g) electrically connecting said first new phase conductor to a first segment of said second phase-needing-maintenance on opposite sides of said third dead end juncture, and electrically connecting said first new phase conductor to a second segment of said second phase-needing-maintenance on opposite sides of said fourth dead end juncture, so as to complete a second electrically parallel connection between said first new phase conductor and said second phase-needing-maintenance, h) electrically disconnecting said second section of said second phase-needing-maintenance so as to isolate said second section of said second phase-needing-maintenance from said first and second segments of said second phase-needing-maintenance and said first new phase conductor, and i) maintaining said second section of said second phase-needing-maintenance
