SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of quarter bends allowed in a single run of Electrical
Metallic Tubing (EMT) between pull points?
,A. Two
B. Three
C. Four
D. Six
🟢 C. Four
🔴 Explanation: According to the NEC, there shall not be more than the equivalent of four
quarter bends (360 degrees total) between pull points to prevent damage to conductor
insulation during pulling.
2. A 120-volt circuit has a total resistance of 15 ohms. What is the current flowing
through the circuit?
A. 8 amperes
B. 10 amperes
C. 12 amperes
D. 1800 amperes
🟢 A. 8 amperes
🔴 Explanation: Using Ohm’s Law (I = E / R), 120 volts divided by 15 ohms equals 8
amperes.
, 3. Which of the following is the required color for a high-leg conductor in a 4-wire,
delta-connected secondary system?
A. Red
B. Orange
C. Blue
D. Brown
🟢 B. Orange
🔴 Explanation: The NEC requires the high-leg of a 4-wire, delta-connected system to be
identified by an outer finish that is orange in color.
4. In a residential kitchen, what is the minimum number of 20-ampere small-appliance
branch circuits required for countertop outlets?
A. One
B. Two
C. Three
D. Four
🟢 B. Two
, 🔴 Explanation: The NEC mandates at least two 20-ampere small-appliance branch
circuits to supply all receptacle outlets for the kitchen countertop.
5. What is the minimum clear working space depth in front of electrical equipment
operating at 480 volts to ground where there are live parts on one side and
grounded parts on the other (Condition 2)?
A. 3 feet
B. 3.5 feet
C. 4 feet
D. 5 feet
🟢 B. 3.5 feet
🔴 Explanation: For voltages between 151 and 600 volts to ground, Condition 2 requires
a minimum depth of 3.5 feet for working space.
6. A branch circuit supplies a continuous load of 40 amperes. What is the minimum
ampacity required for the branch-circuit conductors?
A. 40 amperes
B. 45 amperes
