Questions and CORRECT Answers
medium cable - CORRECT ANSWER - cable rated at up to 35,000 volts.
133 % insulation level - CORRECT ANSWER - must have adequate assurance that the faulted
section will be cleared within 1 hour.
employee - CORRECT ANSWER - has legal rights and is entitled to protection for safety on the
job.
fall arrest system - CORRECT ANSWER - must be worn when preparing to install a termination
from an aerial bucket.
insulating tape - CORRECT ANSWER - is a highly conformable, self-fusing ethylene propylene
rubber (EPR) tape that may have a 'snakeskin' liner that is easily removed as the tape is applied.
annular conductor - CORRECT ANSWER - is generally used for sizes above 1,000 MCM to help
combat the 'skin effect' problem.
poor workmanship - CORRECT ANSWER - is a common cause due to strands of material left in
joint.
tape splice - CORRECT ANSWER - requires that the cable insulation ends are penciled in addition
to the normal cable cutbacks.
insulation shield - CORRECT ANSWER - must be carefully removed to leave a smooth, square
leading edge to minimize electrical stresses.
low-voltage secondary cables - CORRECT ANSWER - generally consist of conductor strands,
insulations, and sometimes an outer jacket.
, termination procedures - CORRECT ANSWER - for low-voltage secondary cables are far more
complex than high-voltage primary cables.
external ground - CORRECT ANSWER - should be provided that is connected to the cable shield
at the base of the termination; it should be installed even if it is not used.
Corona - CORRECT ANSWER - is another name for a partial discharge.
splice jacket - CORRECT ANSWER - provides mechanical protection and moisture sealing.
Insulation - CORRECT ANSWER - covers the entire splice insulation.
splice kits - CORRECT ANSWER - are easier and faster to install but are sensitive to the proper
kit selection, cable preparation dimensions, and unique installation steps.
bushing well - CORRECT ANSWER - is an apparatus bushing component that forms a cavity to
accept an accessory.
200-ampere elbows - CORRECT ANSWER - are sized to fit up to 4/0 AWG copper or 250 kcmil
aluminum conductor.
600-ampere connecting component - CORRECT ANSWER - made of copper instead of aluminum
is rated at 900 A.
IEEE 386 - CORRECT ANSWER - states that elbows are available in 2 general categories.
600-ampere elbows - CORRECT ANSWER - are designed to operate as a dead break only.
poorly grounded cables - CORRECT ANSWER - are vulnerable to outages and to being damaged
by surges.
