1.
Under Maryland licensing requirements, which experience is generally
required to qualify for the master electrician examination?
A. Two years of electrical experience
B. Four years of electrical experience
C. Seven years of qualifying electrical experience
D. Ten years of electrical experience
Answer: C. Seven years of qualifying electrical experience
Rationale: Maryland generally requires an applicant for the master
electrician examination to have at least seven years of regular and
principal electrical-service experience under the direction and
supervision of a master electrician or similarly qualified governmental
employee. Certain formal education or training may receive credit
toward the requirement.
2.
Which organization administers the Maryland master electrician
licensing examination?
,A. National Electrical Contractors Association
B. PSI Examination Services
C. Occupational Safety and Health Administration
D. National Fire Protection Association
Answer: B. PSI Examination Services
Rationale: Maryland uses PSI as its examination vendor for electrician
licensing examinations. The State Board establishes the licensing
requirements, while PSI administers the examination process
according to the approved examination program.
3.
The Maryland master electrician examination is primarily based on
which technical code?
A. International Plumbing Code
B. International Mechanical Code
C. National Electrical Code
D. International Fuel Gas Code
Answer: C. National Electrical Code
Rationale: Maryland’s electrician licensing examination is based on
the applicable current National Electrical Code requirements together
with applicable Maryland laws, regulations, and other examination
references. Candidates must study both technical requirements and
jurisdiction-specific provisions.
4.
If a Maryland law conflicts with a national code provision, which
requirement controls?
,A. The national code always controls
B. The manufacturer's instructions always control
C. The Maryland legal requirement controls
D. The contractor may select either requirement
Answer: C. The Maryland legal requirement controls
Rationale: State-specific legal requirements take precedence when they
conflict with national requirements. A master electrician must
therefore understand not only the NEC but also Maryland statutes,
regulations, licensing provisions, and applicable local requirements.
5.
What is the principal purpose of the National Electrical Code?
A. To establish electrical utility rates
B. To provide practical safeguards for persons and property from
electrical hazards
C. To determine contractor profit margins
D. To regulate electrician wages
Answer: B. To provide practical safeguards for persons and property
from electrical hazards
Rationale: The NEC establishes minimum safety requirements
intended to protect people and property from hazards arising from
electricity. It is not primarily a design manual, pricing guide, licensing
statute, or utility-rate document.
6.
Which formula expresses Ohm's Law?
A. P = EI
B. E = IR
, C. R = EI
D. I = ER
Answer: B. E = IR
Rationale: Ohm's Law states that voltage equals current multiplied by
resistance. The relationship can also be rearranged to determine
current or resistance, making it fundamental for troubleshooting and
electrical calculations.
7.
A 120-volt circuit has a resistance of 20 ohms. Approximately how
much current flows?
A. 2 A
B. 4 A
C. 6 A
D. 10 A
Answer: C. 6 A
Rationale: Using I = E/R, the current is 120 volts divided by 20 ohms,
which equals 6 amperes. Ohm's Law calculations are frequently used
to evaluate circuit operation and identify abnormal conditions.
8.
What is the power consumed by a 120-volt load drawing 10 amperes?
A. 120 W
B. 600 W
C. 1,000 W
D. 1,200 W
Answer: D. 1,200 W
