Apprentice Lineman Test Questions and Concepts latest
version test actual questions and verified answers with
complete solutions.
ASCR - ANSWER: The steel reinforcement of ASCR allows less sag, and
shorter structures.
Self-dampening conductor - ANSWER: A conductor considered a self-
dampening conductor.
Groundman position - ANSWER: Where the groundman should stand
when pulling up material to the worker on the pole: At a 15° angle to the
load.
Lag screws installation - ANSWER: Lag screws should be installed into a
wooden pole by driving the lag screw in with a hammer and using a
wrench to seat the lag for the last part.
Flashover on insulators - ANSWER: Known reasons that might cause
flashover on insulators include dirt, moisture, and lightning.
BIL rating - ANSWER: Insulators have a BIL rating, which is the measure
of the insulator's ability to withstand high voltage surges.
Post insulators - ANSWER: Post insulators are used when a line is built
on a narrow right-of-way or along a rocky terrain.
Suspension insulators - ANSWER: Nine suspension insulators are
typically found in a 138-kV circuit.
, Ohmmeter - ANSWER: An instrument that measures the value of a
resistor.
Series resistance formula - ANSWER: The mathematical expression for
series resistance is R = R₁ + R₂ + R₃ + ... + Rn.
Heat production - ANSWER: Anytime current flows through a resistance,
heat is produced.
Power consumed by motor - ANSWER: If an electric motor draws six
amperes and has a resistance of 13.33 ohms, the power consumed by
this motor is 480 W.
Mechanical advantage of block and tackle - ANSWER: This block and
tackle provides a mechanical advantage of 4 to 1.
Single-block usage - ANSWER: A single-block hung from a crossarm is
used to change the pull direction of a rope.
Sling tension - ANSWER: Equals the load being lifted when using a two-
sling bridle hitch where the sling angle is 10°, 25°, 30°, or 45°.
Acceptable circumstances for knotting slings - ANSWER: When the knot
is under the object in a basket configuration, when the load is less than
half the working load limit of the slings, or when you need a different
attachment at the end to safely connect to the lift device.
Sling shock loading - ANSWER: The rapid lowering and a sudden stop of
the load, or having a load stick then come free.
