1. Which of the following best describes the primary purpose of licensing
requirements for a Maryland Limited Electrician?
A. To increase competition among contractors
B. To ensure electrical work is performed safely and according to
applicable codes
C. To eliminate the need for inspections
D. To reduce the cost of electrical materials
B. To ensure electrical work is performed safely and according to applicable
codes
Rationale: Licensing laws exist to protect public health, safety, and welfare
by ensuring that electricians possess the technical knowledge and
competency required to perform electrical work safely and in compliance
with state and local regulations.
2. A Maryland Limited Electrician is generally authorized to:
A. Perform all electrical work without limitation
, B. Install only low-voltage systems
C. Perform electrical work within the scope and limitations established
by the license classification
D. Work only under direct supervision of a master electrician at all
times
C. Perform electrical work within the scope and limitations established by
the license classification
Rationale: A limited electrician license authorizes work only within defined
categories or limitations established by the issuing authority, unlike
unrestricted master electrician licenses.
3. Which code is most commonly adopted as the standard for electrical
installations in Maryland jurisdictions?
A. International Plumbing Code
B. National Electrical Code
C. International Mechanical Code
D. National Fire Protection Building Code
B. National Electrical Code
Rationale: The National Electrical Code (NEC), published by NFPA, is the
primary standard governing safe electrical installations throughout the
United States, including Maryland jurisdictions.
4. Before beginning electrical work, a licensed electrician should first:
A. Purchase all equipment
B. Notify the utility company
C. Obtain required permits and approvals
D. Hire an inspector
C. Obtain required permits and approvals
,Rationale: Electrical permits and approvals are required to ensure that
installations are reviewed and inspected for compliance with applicable
safety codes before work proceeds.
5. What is the primary hazard associated with overloaded electrical
circuits?
A. Reduced voltage drop
B. Excessive grounding resistance
C. Fire caused by overheating conductors
D. Increased power factor
C. Fire caused by overheating conductors
Rationale: Overloaded circuits cause conductors to carry current beyond
their ampacity, generating excessive heat that can damage insulation and
create fire hazards.
6. Conductors are sized primarily according to:
A. Color of insulation
B. Length of raceway only
C. Current-carrying capacity and voltage drop considerations
D. Manufacturer preference
C. Current-carrying capacity and voltage drop considerations
Rationale: Proper conductor sizing depends on ampacity, voltage drop,
insulation type, temperature rating, and installation conditions to ensure
safe system operation.
7. What is the purpose of grounding electrical systems?
A. To increase circuit voltage
B. To reduce conductor costs
C. To provide a safe path for fault current
D. To eliminate the need for overcurrent protection
, C. To provide a safe path for fault current
Rationale: Grounding stabilizes system voltage and provides a low-
resistance path for fault current, helping overcurrent devices operate
quickly during faults.
8. Which device is intended to protect people from electrical shock in
wet or damp locations?
A. AFCI
B. GFCI
C. Disconnect switch
D. Transformer
B. GFCI
Rationale: Ground-fault circuit interrupters detect imbalances between
ungrounded and grounded conductors and rapidly disconnect power to
reduce shock hazards.
9. What is the function of an overcurrent protective device?
A. To improve lighting efficiency
B. To regulate transformer frequency
C. To open a circuit when excessive current flows
D. To increase electrical resistance
C. To open a circuit when excessive current flows
Rationale: Overcurrent devices such as circuit breakers and fuses protect
conductors and equipment from damage caused by overloads and short
circuits.
10. In electrical terminology, voltage is defined as:
A. The flow of electrons through a conductor
B. Electrical pressure that causes current flow
