The use of such procedures on DOD installations requires that good practice be followed and that there is no conflict with local facility rules.
a.Good practice. Personnel doing live-line work should have satisfactorily completed a formal training course of instruction and be examined periodically. Live-line maintenance usually means any maintenance activity performed on energized electrical conductors or equipment with a phase-to-phase voltage exceeding 600 volts. It usually does not include such activities as switching, hardware tightening, climbing, hole digging, pole setting, conductor stringing, etc. The performance of this work requires equipment and tools that meet applicable industry standards for energized-line maintenance.
b.Local facility rules. Two considerations affect facility rules on the type and extent of live-line maintenance permitted: availability of qualified facility personnel and equipment versus the facility's requirement for uninterrupted operation. If local missions prevent electrical power shutdowns and local facilities are not qualified to perform live-line

work, then a live-line contractor may need to be hired on a scheduled and/or a nonscheduled basis. General energized-line maintenance practices covered in chapter 4, section VI, serve only as a guide
and are not intended to substitute for training or operating procedures; for meeting specific industry guidelines; or for meeting federal, state, local, or facility regulations and rules.
