1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To reduce the cost of electrical installations
B. To provide practical safeguards for persons and property from
electrical hazards
C. To establish electrical licensing requirements
D. To regulate utility power generation
Rationale: The NEC is intended to provide practical safeguarding of
persons and property from hazards arising from the use of electricity.
It is not a design specification or instruction manual, nor does it
establish licensing requirements.
, 2. Which NEC chapter generally applies to all electrical installations
unless modified by later chapters?
A. Chapter 9
B. Chapter 8
C. Chapters 1 through 4
D. Chapter 7
Rationale: Chapters 1 through 4 contain the general requirements that
apply to most electrical installations. Chapters 5, 6, and 7 supplement
or modify these requirements for special occupancies, equipment, or
conditions, while Chapter 8 generally stands alone.
3. Conductors installed in raceways are generally required to have
insulation suitable for:
A. Mechanical stress only
B. The voltage and environmental conditions of the installation
C. Indoor use only
D. Low-voltage communication systems only
Rationale: Conductor insulation must be suitable for the operating
voltage, temperature, moisture, chemicals, sunlight exposure, and
other environmental conditions where it is installed.
, 4. The grounded conductor is commonly identified by which color?
A. Green
B. Red
C. White or gray
D. Orange
Rationale: The grounded conductor (neutral) is identified by white or
gray insulation or approved markings. Green or bare conductors are
reserved for equipment grounding conductors.
5. Which conductor is permitted to be bare?
A. Ungrounded conductor
B. Neutral conductor
C. Traveler conductor
D. Equipment grounding conductor
Rationale: Equipment grounding conductors are permitted to be bare,
covered, or insulated. Current-carrying conductors generally require
insulation.
, 6. What is the minimum working space depth in front of 120/240-
volt equipment under Condition 2?
A. 2 feet
B. 3 feet
C. 4 feet
D. 5 feet
Rationale: NEC working space requirements are based on voltage and
conditions surrounding the equipment. For many installations
involving 120/240-volt equipment under Condition 2, the minimum
depth is 3 feet.
7. A junction box must remain:
A. Painted over after installation
B. Hidden above finished ceilings
C. Accessible without removing building finish
D. Filled completely with insulation
Rationale: Junction boxes must remain accessible so conductors can be
inspected, repaired, or modified without damaging the building.
