Electrical Craft Helper Exam Questions & Answers 2026 |
High-Yield Review | Graded A+
1. If an electrician is troubleshooting a circuit and finds that the multimeter
shows no continuity, what does this indicate about the circuit?
The multimeter is malfunctioning.
The circuit is functioning normally.
The circuit has too much resistance.
There is a break or fault in the circuit.
2. In a scenario where an electrician needs to assemble a junction box, which
tool would be most appropriate to use for securing the box to the wall?
Fish tape
A socket set
Wire strippers
A multimeter
3. In a scenario where an electrical installation requires mounting a heavy
fixture, which tool would be most appropriate to use and why?
Cutting tools, because they can trim the fixture to fit.
A power drill, because it can efficiently drill holes and drive screws
to securely mount the fixture.
A multimeter, because it can measure the electrical load on the
fixture.
Fish tape, because it can help pull wires to the fixture location.
,4. Describe how a socket set contributes to the efficiency of electrical
installations.
A socket set is used to cut wires to specific lengths.
A socket set allows electricians to quickly and effectively tighten or
loosen nuts and bolts, improving installation speed and reducing
the risk of damage.
A socket set is primarily used for measuring electrical resistance in
circuits.
A socket set helps in pulling wires through tight spaces.
5. What is the advantage of using cable cutters capable of cutting conductors
through 1,000 kcmil?
They are not specifically designed for stripping insulation
They work efficiently only for midspan stripping.
They save time compared to using a hacksaw
They are suitable for use with smaller conductors.
6. A socket set is an integral part of a technician's toolbox because.
The ratchet handle can loosen and tighten a nut or hex head bolt with
minimal movement
there are multiple sockets that can be interchanged easily to
accommodate different size nuts and bolts
the extension allows easier access to nuts and bolts in tight locations
All of the above
, 7. Describe how a torpedo level contributes to the quality of electrical
installations.
A torpedo level assists in cutting wires to the correct length.
A torpedo level is used to measure voltage levels in circuits.
A torpedo level helps ensure that electrical installations are
properly aligned, which is crucial for both aesthetics and
functionality.
A torpedo level is primarily used for pulling wires through tight
spaces.
8. If an electrical craft helper is working in an area with a high risk of arc flash,
what type of clothing should they wear to ensure safety?
Cotton clothing
Flame retardant clothing
Leather gloves
Regular work attire
9. What is the primary purpose of a voltage tester in electrical work?
Provides insulation resistance readings
Measures current flow in a circuit
Cuts wires to specific lengths
Detects live wires and verifies de-energized circuits
10. If an electrical helper needs to install a conduit that is 25 feet long, how
would they use a tape measure to ensure proper installation?
