ARKANSAS MASTER ELECTRICIAN EXAM REVIEWS WITH
COMPLETE ACTUAL EXAM QUESTIONS AND CORRECT VERIFIED
ANSWERS/ ALREADY GRADED A+ (MOST RECENT!!)
1. A contractor is designing the service for a mixed-use building
containing retail space on the first floor and apartments above. Before
selecting the service equipment, what should be completed first?
A. Selecting the panelboard manufacturer
B. Performing a comprehensive electrical load calculation
C. Installing the grounding electrode system
D. Determining conduit support spacing
Answer: B
Rationale: Proper service design begins with an accurate load
calculation to ensure conductors and equipment are correctly sized.
2. During commissioning of a three-phase motor, the measured current
on one phase is significantly higher than on the other two phases. What
is the most likely cause?
A. Balanced load conditions
B. Phase imbalance or a defective connection
, 2|Page
C. Oversized conduit
D. Incorrect panel labeling
Answer: B
Rationale: Unequal phase currents commonly indicate an unbalanced
load, loose termination, or wiring problem.
3. A feeder supplying sensitive electronic equipment experiences
excessive voltage drop during periods of peak demand. Which design
change would most effectively reduce the voltage drop?
A. Increase conductor size.
B. Install additional lighting fixtures.
C. Increase the number of junction boxes.
D. Replace receptacles with different colors.
Answer: A
Rationale: Increasing conductor size reduces resistance, helping
minimize voltage drop over long distances.
