ISA UTILITY SPECIALIST 2026 UPDATED EXAM TEST
PAPER QUESTIONS AND ANSWERS SURE A+
✔✔Coriolis Force - ✔✔effect that causes deflection of moving objects to right in N
Hemisphere & left in S hemisphere due to Earth's rotation
✔✔Corrosive - ✔✔substance that damages animals at the point of contact
✔✔Cost Center - ✔✔accounting configuration for expenditures that do not generate
income
✔✔Cover-Type Conversion - ✔✔biological control in which plant commu is converted
form incompatible using selective techniques that provide a competitive advtg to short
growing, early successional plants, allowing them to thrive & successfully compete
against unwanted tree species for sunlight, essential nutrients & water
✔✔Cover-Type Mapping - ✔✔technique that uses aerial photos followed by ground
checks to determine the nature of plant commu on a site
✔✔Credential - ✔✔ISA cert of industry qualification-----certifies that individual has
attained generally accepted level of knowledge in specific subject area or profession
✔✔Crew - ✔✔basic unit of personnel & equipment---2+ people led by foreperson
,-characterized by specialized skills & type of equipment used----manual, lift, off-road,
etc
✔✔Crisis Management - ✔✔reacting to conditions rather than working toward long-term
objectives
-characteristic of program w poorly defined management strategies: ineffective
management, underfunded/understaffed, undereducated manager/workforce
✔✔Critical Path - ✔✔project management----longest period of time a series of tasks
requires from project beginning to end
✔✔Critical Service Provider - ✔✔org, company, etc whose incapacitation or destruction
would have debilitating effect on public interests
✔✔Cultural Control Method - ✔✔control method that modifies habitat to discourage
incompatible veg & establish & manage compatible commu
-pruning/removal
✔✔Current - ✔✔flow of electricity
✔✔Current Surge - ✔✔inrush of electricity caused when electrical devices(motors/xfmr)
are first switched on----can draw sever times their normal operating electrical load
-circuits are first energized following outage
✔✔Customer Relations - ✔✔discussion & negotiations w individual custys
✔✔Customer Service - ✔✔attention to customer's interests before, during & after
vegetation management work
✔✔Cutout - ✔✔combination fuse & switch used in overhead primary lines to protect
distribution xfmr from current surges & overloads
-overcurrent caused by a fault will cause fuse to melt, disconnecting the xfmr from the
lines
-can be opened manually by utility linemen
✔✔Cycle - ✔✔VM-----planned interval btwn scheduled maintenance established to
maintain adequate clearance btwn trees & utilities
✔✔Cyclone - ✔✔large area of low atmospheric pressure characterized by inward
spiraling winds
✔✔Decision Package - ✔✔proposal or plan that outlines project expenditures, outputs
& alternatives, which receive funding in order of priority
, ✔✔Defects - ✔✔TRAQ-----injuries, growth patterns, decay or conditions that reduce
trees structural strength
✔✔Deferring Maintenance - ✔✔delaying work, usually for financial reasons
✔✔Delta Construction - ✔✔electrical distribution configuration w three phases---no
common neutral wire
-no fixed diff btwn phase-to-phase & phase-to-ground voltages
✔✔Dependencies - ✔✔relationships that dictate when tasks in the work breakdown &s
structure begin & end
✔✔Derecho - ✔✔complex of thunderstorms that travels more than 240 miles w wind
speeds greater than 58 mph
✔✔Desensitization - ✔✔personnel become indifferent or disconnected form
customer/concerns
✔✔Direct Contact - ✔✔electrical contact that occurs when someone touches an
energize fixture
✔✔Directional Pruning - ✔✔selective removal of branches to guide or discourage
growth in a particular direction
✔✔Disaster - ✔✔natural/man made occurrence disrupting the normal conditions of
existence & causing level of suffering that exceeds the capacity of adjustment of the
affected community
✔✔Disaster Declaration - ✔✔proclamation by a government that releases resources or
expedites the response to a disaster(state of emergency)
✔✔Disconnect Switch - ✔✔manual device that isolates the lines or circuits----allowing
visual confirmation that it is open
-not a protection device----used to isolate areas undergoing outage or reroute electricity
from an adjacent energized energized circuit to an affected are to limit outage extent
✔✔Distribution Lines - ✔✔electrical supply lines energized btwn 2.4-23kV
✔✔Distribution Network - ✔✔electrical utility sys----portion that delivers electricity to end
user
-includes substations, primaries, xfmr, secondaries & service lines
✔✔Dose - ✔✔quantity of substance absorbed into the body
