LADWP Electrical Helper Exam Practice
Questions and Correct Answers (Verified
Answers) Plus Rationale
Question 1
Metal is removed in sawing and filing by the action of many small teeth. Saw teeth act
in a narrow line, and a saw can sever a sizable chunk of metal with a minimum
amount of cutting. If a piece of metal is removed by milling, for instance, a large part
or all of it may have to be reduced to small chips. The same piece may be cut off or
out by a saw acting on only a small part of the material. Thus, in many cases, work can
be done faster and with less power by sawing than by other methods of metal
cutting, and material can be saved.
According to the above paragraph, which of the following is true?
A. milling is more wasteful than sawing for any operation
B. for some jobs, saws are the most useful metal working tools
C. sawing is not as accurate as milling
D. saws remove metal by cutting, whereas mills remove it by shearing
Correct Answer
B. for some jobs, saws are the most useful metal working tools

one which will be third is ________
A. Engineers & Architects Assn. of So. Calif.
B. Engineering Service Corp.
C. Engineering Products Co.
D. Engine Supply Co.
Correct Answer

,Question 6
If the following banks were filed in correct alphabetical order, the one which would be
fourth is _______
A. Bank of California

Correct Answer
B. Security 1st National Bank
Question 1: An Electrical Craft Helper is assisting a journey-level electrician in
preparing to work on a de-energized circuit. According to standard electrical safety
practices used by utilities such as LADWP, what is the most important first step before
beginning any work on the circuit?
A. Begin removing covers immediately to save time
B. Verify that the circuit has been properly locked out, tagged out, and tested for
absence of voltage using an appropriately rated tester
C. Assume the circuit is safe because the supervisor said it was de-energized
D. Wear only leather gloves and proceed with the work
CORRECT ANSWER: B. Verify that the circuit has been properly locked out, tagged out,
and tested for absence of voltage using an appropriately rated tester
Rationale: Proper lockout/tagout procedures combined with verification of zero
energy state using a tested and rated voltage tester are fundamental safety
requirements to prevent accidental energization and protect workers from electrical
shock or arc flash hazards.
Question 2: When measuring the length of a piece of electrical cable that must be cut
for installation, which of the following tools and techniques would be most
appropriate for an Electrical Craft Helper to use to ensure accuracy?
A. Estimating the length by eye and cutting with a hacksaw
B. Using a calibrated measuring tape or rule and marking the cable clearly before
cutting
C. Stretching the cable by hand and cutting at an approximate point
D. Using a non-calibrated piece of scrap wire as a measuring guide
CORRECT ANSWER: B. Using a calibrated measuring tape or rule and marking the
cable clearly before cutting
Rationale: Accurate measurement with a proper measuring tool prevents material
waste, ensures the cable fits the intended run, and supports quality installation

, practices required in utility and facility electrical work.
Question 3: According to basic Ohm’s Law relationships that an Electrical Craft Helper
should understand, if the voltage applied to a resistive circuit is doubled while the
resistance remains constant, what happens to the current?
A. The current is halved
B. The current remains the same
C. The current is doubled
D. The current is quadrupled
CORRECT ANSWER: C. The current is doubled
Rationale: Ohm’s Law states that current is directly proportional to voltage when
resistance is constant (I = V/R). Doubling the voltage therefore doubles the current
flowing through the circuit.
Question 4: An Electrical Craft Helper is required to lift a heavy spool of wire from the
ground onto a truck bed. Which of the following describes the safest lifting technique?
A. Bending at the waist with a straight back and lifting with the back muscles
B. Keeping the back straight, bending at the knees, and lifting with the leg muscles
while keeping the load close to the body
C. Twisting the torso while lifting to place the load more quickly
D. Lifting the spool with one hand while holding tools in the other hand
CORRECT ANSWER: B. Keeping the back straight, bending at the knees, and lifting
with the leg muscles while keeping the load close to the body
Rationale: Proper lifting technique uses the strong leg muscles rather than the back,
keeps the load close to the body’s center of gravity, and reduces the risk of
musculoskeletal injury, which is a primary safety focus for craft helper positions.
Question 5: Which of the following knots is commonly used in electrical craft work to
secure a hand line or to form a temporary loop that will not slip under load?
A. Square knot only
B. Bowline knot
C. Granny knot
D. Overhand knot used alone
CORRECT ANSWER: B. Bowline knot
Rationale: The bowline forms a secure, non-slipping loop that is easy to untie after
loading and is widely taught for use with hand lines, tag lines, and temporary
securing of materials in electrical and utility work.
