1. What is the primary purpose of an electrical grounding system?
A. To carry normal load current
B. To reduce voltage drop
C. To provide a safe path for fault current
D. To increase circuit efficiency
Answer: C
Rationale: Grounding provides a low-resistance path for fault current, reducing
shock and fire hazards.
2. Which tool is best for tightening electrical terminal screws to a specified
torque?
A. Lineman’s pliers
B. Flat-head screwdriver
C. Torque screwdriver
D. Adjustable wrench
Answer: C
Rationale: A torque screwdriver ensures terminals are tightened to
manufacturer specifications, preventing overheating or damage.
, 3. What color insulation is typically used for grounded (neutral) conductors in
AC systems?
A. Green
B. Red
C. White or gray
D. Black
Answer: C
Rationale: Electrical codes identify grounded conductors by white or gray
insulation.
4. Which device protects a circuit from overloads and short circuits?
A. Switch
B. Receptacle
C. Circuit breaker
D. Transformer
Answer: C
Rationale: Circuit breakers automatically open a circuit when excessive current
flows.
5. What is the unit of electrical resistance?
A. Volt
B. Ampere
C. Watt
D. Ohm
Answer: D
Rationale: Resistance is measured in ohms, indicating opposition to current
flow.
6. Which type of conduit is commonly used indoors in dry locations?
A. Rigid metal conduit
B. Liquidtight flexible conduit
, C. Electrical metallic tubing (EMT)
D. PVC Schedule 80
Answer: C
Rationale: EMT is lightweight, easy to install, and suitable for dry indoor
locations.
7. What is the purpose of a GFCI?
A. Protect equipment from overload
B. Increase voltage stability
C. Protect people from ground-fault shock
D. Reduce energy consumption
Answer: C
Rationale: GFCIs quickly disconnect power when a ground fault is detected,
preventing electric shock.
8. Which law states that voltage equals current times resistance?
A. Faraday’s Law
B. Kirchhoff’s Law
C. Ohm’s Law
D. Coulomb’s Law
Answer: C
Rationale: Ohm’s Law defines the relationship V = I × R.
9. What is the minimum personal protective equipment when working on
energized circuits?
A. Safety boots only
B. Insulated gloves only
C. Appropriate PPE including gloves and eye protection
D. Hard hat only
