AUTO TECH ELECTRICAL SECTION EXAM 3
EXAMINATION TEST 2026 QUESTIONS
WITH SOLUTIONS
◉ . Answer: Grounding controls the amount of current that will pass
through a worker.
Grounding conductors must be big enough to handle the available fault
current at that location.
◉ bonding. Answer: must be installed so that a worker is kept in an
equipotential zone. Within the equipotential zone, a worker must not be
able to touch any two objects at different voltages.
◉ . Answer: Bonding controls voltage to which a worker will be
exposed.
◉ job briefing. Answer: a short informal discussion of the work to be
accomplished and the safety measures to be incorporated.
◉ job briefing talk abouts. Answer: a. Hazards associated with the job
b. Work procedures involved
c. Special precautions
d. Energy source controls
, e. Personal protective equipment
and at least one job briefing talk before the start of a job every day
◉ three phase circuit. Answer: all 3 phases are connected, one delivers
the other two act as a return path
◉ why three phase. Answer: three phase have a smoother delivery of
power, power is constant, and three phase can carry twice amount of
load then single phase
◉ three phase. Answer: coils are mounted 120 degrees appart, Each coil
produces AC and voltage,
They reach peak values at 120 degrees,
Essentially there are 3 circuits connected to form a 3-Ø circuit
◉ basic properties of a three phase circuit. Answer: Three-phase systems
have either three or four conductors.
The three phases are 120 degrees out of phase with each other (360
divided by 3).
The fourth conductor is the neutral.
◉ wye. Answer: The wye, or star, connection is made by connecting one
end of each of the phase windings together in a common node.
