ELE 146 CERTIFICATION SCRIPT 2026
QUESTIONS WITH SOLUTIONS
GRADED A+
◍ From the voltage measurements, what can you tell about the condition of the
battery, wiring, and light bulb? Be as specific as you can. Identify which of
the four measurements are unnecessary in determining the precise location
of the fault in this circuit..
Answer: Light bulb is okay. Open load is between D and E. E and J is
unnecessary. Check the bulb, circuit breaker and fuses.
◍ How do I check for current?.
Answer: Make sure the probes are in a series
◍ High dielectric.
Answer: Todays liquid-filled transformers have their windings immersed in
highly refined mineral oil (combustible), silicone fluid, edible seed oil-based
dielectric coolant, or other acceptable nontoxic liquids that have ___
properties.
◍ How do I check for voltage?.
Answer: Make sure their parallel and use a plant meter
◍ Running current through a wire creates.
Answer: magnetic field
◍ In a transformer circuit you can not use.
Answer: DC
◍ NESC.
Answer: Utilities make up connections on the line side and load side of their
transformers according to the ___ requirements.
, ◍ Open delta.
Answer: The ___ connection scheme has the advantage of being able to
provide either 3-phase or 3-phase and single-phase power using only two
transformers.
◍ Make sure I disconnect power before checking for resistance.
Answer: True
◍ thinner wire has more resistance than a thicker wire.
Answer: True
◍ Open voltage is infinite resistance.
Answer: True
◍ More than likely I will blow a fuse if I'm checking for current. Start by
checking the larger one first.
Answer: True
◍ In a parallel circuit voltage is the same.
Answer: True
◍ Service point.
Answer: The ___ is defined in NEC Article 100 as the point of connection
between the facilities of the serving utility and the premises wiring.
◍ The earth.
Answer: Throughout this country, and for that matter, throughout the world,
___ is(are) the common reference point for all electrical systems.
◍ Ground faults.
Answer: ___ occur when an underground "hot" conductor comes in contact
with a grounded surface or grounded equipment.
◍ Magnetic flux line has an easier time going through soft iron.
Answer: True
◍ Phase-to-ground.
Answer: GFPE monitors are designed to sense ___ faults only.
