energize cable constructed from aluminum wire stranded around a steel core -lightweight, low cost -tendency to stretch when heated ----high electrical load or high temp -to minimize stretch/add strength ----steel core is added Ampere(amp, A) - ANSWER -measure of current - 1 A = charge carried by 6.25 x 10^18 electrons moving past a given point in one second -ANSI A300(Part 7) - ANSWER -American National Standard for Tree Care Operations ----Tree/Shrub/Wood Plant Maintenance -IVM---utility ROW ANSI Z133 - ANSWER -ANSI Arboricultural Operations ----Safety Reqs -safety standard of practice for tree care Approach Distance - ANSWER -minimum distance that must be kept btwn conductors/energized equipment & qualified line clearance personnel & non -qualified & bodies/tools -approach distance vary w qualifications of personnel & voltages Automatic Line Recloser - ANSWER -circuit breaker equipped w mechanism that auto close the breaker after it has been opened due to a. fault -designed to reset quickly to give the cause of a fault opp to clear -may immediately recharge the circuit several times at adjustable time delay ----2/3 operations within seconds before they open permanently Auxin - ANSWER -plant growth regulator or substance that promotes/influences the growth & development of plants -produced at sites where cells are dividing primarily in the shoot tips -auxin like compounds may be produced synthetically Auxin Transport Inhibitors - ANSWER -class of selective herbicides that disrupt auxin transport -auxin transport obstruction causes unnatural concentration of auxin in meristematic shoots & roots, disturbing the auxin tolerances req for normal plant growth
