Section Two: Questions 101–200
101. What is the maximum number of 12 AWG conductors allowed in a 4" x 1-1/2" square metal box?
A. 7
B. 9
C. 10
D. 12
🟢 B. 9
🔴 Explanation: Per NEC Table 314.16(A), a 4" x 1-1/2" square box has a volume of 21.0 cubic inches. 21..25 (for
12 AWG) = 9.33, which allows for 9 conductors.
102. For a motor branch circuit, the short-circuit and ground-fault protective device (standard circuit breaker) shall
generally not exceed what percentage of the motor full-load current?
A. 125%
B. 175%
C. 250%
D. 300%
🟢 C. 250%
🔴 Explanation: Table 430.52 specifies that for an inverse time circuit breaker, the maximum rating is generally 250%
of the motor FLC.
,103. Which of the following is required for a 125V, 15A or 20A receptacle installed in a "Damp Location," such as a
covered porch?
A. Must be AFCI protected
B. Must be Weather-Resistant (WR) type
C. Must be Tamper-Resistant (TR) only
D. Must be red in color
🟢 B. Must be Weather-Resistant (WR) type
🔴 Explanation: NEC 406.9(A) requires all 15A and 20A, 125V and 250V receptacles installed in damp locations to be
listed weather-resistant type.
104. What is the minimum size copper bonding jumper required for a metal water piping system if the service-
entrance conductors are 3/0 AWG copper?
A. 6 AWG
B. 4 AWG
C. 2 AWG
D. 1/0 AWG
🟢 B. 4 AWG
🔴 Explanation: NEC Table 250.102(C)(1) directs the sizing based on the service conductors; for 3/0 AWG copper, a 4
AWG copper bonding jumper is required.
105. A "Qualified Person" as defined by the NEC is one who:
A. Has a college degree in engineering
B. Has skills and knowledge related to the construction and operation of electrical equipment and has received
safety training
,C. Has worked as an apprentice for at least one year
D. Is a licensed general contractor
🟢 B. Has skills and knowledge related to the construction and operation of electrical equipment and has received
safety training
🔴 Explanation: Article 100 defines a qualified person based on specific skills, knowledge of equipment, and safety
training to recognize and avoid hazards.
106. What is the maximum distance a support must be placed from a box or termination for Type NM cable?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
🟢 B. 12 inches
🔴 Explanation: NEC 334.30 requires NM cable to be secured within 12 inches of every outlet box, junction box,
cabinet, or fitting.
107. When three or more current-carrying conductors are installed in a raceway, the allowable ampacity must be
reduced. What is the adjustment factor for 4 to 6 conductors?
A. 90%
B. 80%
C. 70%
D. 50%
🟢 B. 80%
, 🔴 Explanation: NEC Table 310.15(C)(1) specifies an 80% adjustment factor for 4 to 6 current-carrying conductors in
a single raceway.
108. Which color is reserved for the identification of the high-leg conductor in a 240/120V 3-phase Delta system?
A. Yellow
B. Blue
C. Orange
D. Purple
🟢 C. Orange
🔴 Explanation: NEC 110.15 and 230.56 require the high-leg (the phase with the higher voltage to ground) to be
identified with an orange finish.
109. What is the minimum mounting height for a lighting track?
A. 5 feet
B. 6 feet
C. 8 feet
D. No minimum height
🟢 B. 5 feet
🔴 Explanation: NEC 410.151(C)(8) states that lighting track shall be installed not less than 5 feet above the finished
floor unless protected from physical damage.
110. A dwelling unit bathroom must have at least one receptacle outlet located within how many feet of the outside
edge of each basin?
