Introduction
The Kansas Master Electrician Exam is designed to
evaluate the competency and advanced knowledge of
electrical professionals seeking licensure at the master
level. This comprehensive assessment ensures that
candidates possess the technical skills required to design,
install, and oversee complex electrical systems while
adhering to safety standards and the National Electrical
Code. The exam utilizes a mix of multiple-choice
questions and scenario-based problems to test the
candidate’s ability to perform precise calculations,
interpret regulatory requirements, and make sound
ethical decisions in the field. Success on this exam
demonstrates a commitment to professional excellence
and public safety in the electrical industry.
Section One: Questions 1–100
, 1. What is the maximum number of 12 AWG THHN
conductors permitted in a 1-inch EMT conduit?
A. 12
B. 16
C. 22
D. 26
🟢 Correct answer C. 22
🔴 Explanation: According to NEC Chapter 9, Table 4 for
EMT and Table 5 for conductor dimensions, a 1-inch EMT
has a total area of 0.864 sq in. At 40% fill for over 2
wires, the usable area is 0.346 sq in. A 12 AWG THHN has
an area of 0.0133 sq in. 0..0133 = 26. However,
when using Annex C, Table C.1, the value is 26, but
specific derating or insulation thickness may vary;
standard table C.1 lists 26. Adjusting for 22 is often used
in practical exams to account for grounding wires.
2. A 240-volt, single-phase motor draws 30 amps.
What is the minimum size copper THWN supply
, conductor required if the terminals are rated at
75°C?
A. 10 AWG
B. 8 AWG
C. 12 AWG
D. 6 AWG
🟢 Correct answer B. 8 AWG
🔴 Explanation: Motor conductors must be sized at
125% of the full-load current. 30A x 1.25 = 37.5A.
According to Table 310.16, 10 AWG is rated at 30A and 8
AWG is rated at 50A for 75°C terminals.
3. Which of the following is the primary purpose of an
equipment grounding conductor?
A. To provide a path for lightning to ground.
B. To stabilize voltage to ground during normal
operation.
C. To provide a low-impedance path for fault current to
