B. Not permanently closed in by the structure or
finish of the building
C. Capable of being removed or exposed without
damaging the building structure or finish
D. Admittance to a place, especially by a person

Rationale: NEC Article 100 defines "Accessible" (as
applied to equipment) as admitting close approach;
not guarded by locked doors, elevation, or other
effective means. It also means not permanently
closed in by the structure or finish of the building.
This definition is distinct from "Readily Accessible,"
which requires being reached quickly without
climbing over or removing obstacles.

A. The width of the equipment or 24 inches,
whichever is greater
B. The width of the equipment or 30 inches,

C. 36 inches
D. 42 inches
Correct Answer: B
Rationale: NEC 110.26(A)(3) mandates that the
,width of the working space in front of electrical
equipment shall be the width of the equipment or
30 inches, whichever is greater. This requirement
ensures sufficient room for safe operation and
maintenance of the equipment.
3. What is the primary purpose of the National

A. To design electrical systems for maximum
efficiency and cost-effectiveness
B. To provide minimum installation standards for
the practical safeguarding of persons and property
from electrical hazards
C. To certify electrical contractors and journeymen
electricians
D. To calculate electrical utility bills and
consumption rates
Correct Answer: B
Rationale: The purpose of the NEC, as stated in
Article 90.1(A), is the practical safeguarding of
persons and property from hazards arising from the
use of electricity. It sets minimum standards, not
design specifications for efficiency.
, 4. When is a conductor considered to be "in a wet
location"?
A. When it is installed outdoors in a conduit
B. When it is installed in a location subject to
saturation with water or other liquids, such as in
vehicle washing areas, and in unprotected locations
exposed to weather
C. When it is installed in a basement that is subject
to occasional flooding
D. When the ambient relative humidity exceeds
80%
Correct Answer: B
Rationale: NEC Article 100 defines a wet location as
a location subject to saturation with water or other
liquids, such as in vehicle washing areas, and in
unprotected locations exposed to weather. The
definition also includes underground locations and
those in concrete slabs or masonry in direct contact
with the earth.
