Get ready for the New Mexico (NM) EE-98 Residential & Commercial Electrical (Part 3 – Specialties) Practice
Exam with carefully prepared questions covering specialty electrical systems, NEC compliance, grounding and
bonding, motor controls, generators, fire alarms, pools and spas, and other important residential and commercial
installation topics.
,1. What is the primary purpose of bonding in electrical installations?
A. To increase circuit voltage
B. To provide a low-impedance path for fault current
C. To reduce conductor length
D. To improve lighting output
Answer: B. To provide a low-impedance path for fault current
Explanation: Bonding connects metal parts together to ensure fault current has an
effective path back to the source, helping protective devices operate quickly.
2. In a wet location, which wiring method is generally suitable when listed for
the purpose?
A. NM cable
B. ENT without protection
C. Rigid metal conduit
D. Open splices
Answer: C. Rigid metal conduit
Explanation: Rigid metal conduit is commonly permitted in wet locations when
installed properly with fittings suitable for wet environments.
3. What does a disconnecting means primarily provide for specialty
equipment?
A. Voltage boost
B. A means to safely isolate equipment from power
C. Extra ampacity
D. Decorative enclosure support
Answer: B. A means to safely isolate equipment from power
Explanation: Disconnecting means allow equipment to be de-energized for
servicing, maintenance, or emergency shutdown.
4. Which factor is most important when selecting conductors for a motor
circuit?
A. Paint color of the raceway
,B. Motor horsepower and nameplate data
C. Building carpet type
D. Ceiling tile pattern
Answer: B. Motor horsepower and nameplate data
Explanation: Motor circuits are sized using applicable code rules and motor
nameplate information such as current and horsepower.
5. A transformer is mainly used to:
A. Change voltage levels
B. Increase conductor insulation thickness
C. Replace overcurrent devices
D. Eliminate grounding requirements
Answer: A. Change voltage levels
Explanation: Transformers transfer electrical energy between circuits while
stepping voltage up or down as needed
6. What is the function of overcurrent protection?
A. To increase equipment speed
B. To protect conductors and equipment from excessive current
C. To improve conduit appearance
D. To reduce panel labeling needs
Answer: B. To protect conductors and equipment from excessive current
Explanation: Overcurrent devices protect wiring and equipment from overheating
and damage caused by overloads and short circuits.
7. Which installation requires special attention to equipotential bonding?
A. Bedroom receptacles
B. Swimming pools
C. Pantry lighting
D. Office carpet tiles
, Answer: B. Swimming pools
Explanation: Pool installations require equipotential bonding to reduce voltage
gradients and shock hazards around the pool area.
8. Fire alarm system circuits are generally considered:
A. Decorative branch circuits
B. Life-safety related systems
C. Temporary holiday wiring
D. Non-electrical systems only
Answer: B. Life-safety related systems
Explanation: Fire alarm systems are critical life-safety systems and must be
installed in accordance with applicable code requirements.
9. What is the main reason for grounding electrical systems?
A. To make lights brighter
B. To stabilize voltage and reduce fault hazards
C. To eliminate all breakers
D. To increase motor RPM
Answer: B. To stabilize voltage and reduce fault hazards
Explanation: Grounding helps stabilize system voltage and provides a reference to
earth while reducing certain electrical hazards.
10. In specialty installations, equipment in damp or wet locations must have:
A. Cardboard covers
B. Weather-appropriate enclosures
C. Smaller conductors
D. Hidden labels only
Answer: B. Weather-appropriate enclosures
Explanation: Electrical equipment in wet or damp locations must be listed and
enclosed appropriately for the environmental conditions.
