INTRODUCTION
The New Mexico EE98 Residential and Commercial Electrical Examination assesses the competency of
candidates seeking licensure as electrical contractors qualified to perform residential, commercial, and
industrial electrical work operating at 5,000 volts nominal or less. This comprehensive multiple-choice
and scenario-based assessment evaluates foundational electrical theory, applied professional knowledge,
technical concepts, regulatory compliance, and ethical standards. Candidates must demonstrate
proficiency in interpreting the National Electrical Code with New Mexico amendments, performing load
calculations, selecting proper wiring methods, ensuring safety through grounding and bonding, and
exercising sound professional judgment in real-world workplace situations. The examination emphasizes
practical application and critical decision-making required of licensed electrical professionals.
,SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of grounding an electrical system?
A. To increase system voltage for improved efficiency
B. To provide a low-impedance path for fault current to facilitate overcurrent device operation
C. To reduce conductor ampacity requirements
D. To eliminate the need for equipment bonding
🟢 Correct answer: B
🔴 Explanation: Grounding provides a low-impedance path for fault current, enabling overcurrent
protective devices to operate rapidly and clear faults, thereby protecting personnel and equipment
from shock and fire hazards .
Question 2
According to the NEC, what defines a continuous load?
A. A load operating for 30 minutes or more
B. A load operating for 1 hour or more
C. A load where maximum current is expected to continue for 3 hours or more
D. A load operating continuously for 24 hours
🟢 Correct answer: C
🔴 Explanation: NEC Article 100 defines a continuous load as one where the maximum current is
expected to continue for three hours or more. Conductors and overcurrent devices serving continuous
loads must be sized at 125% of the load .
Question 3
What is the minimum working space depth in front of a 480-volt panelboard under typical conditions?
A. 2 feet
,B. 3 feet
C. 4 feet
D. 5 feet
🟢 Correct answer: B
🔴 Explanation: NEC Table 110.26(A)(1) requires a minimum working space depth of 3 feet for
equipment rated 0–150 volts to ground under typical conditions, allowing safe maintenance and
operation .
Question 4
A 20-ampere branch circuit requires a minimum copper conductor size of:
A. 14 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
🟢 Correct answer: B
🔴 Explanation: NEC Table 310.16 permits 12 AWG copper conductors for 20-ampere circuits at 60°C
termination ratings, which is the standard minimum for general-purpose branch circuits .
Question 5
What is the minimum cover depth for a direct-buried residential branch circuit cable rated 0–600
volts?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
🟢 Correct answer: C
🔴 Explanation: NEC Table 300.5 requires 18 inches of cover for direct-buried residential branch circuit
cables rated 0–600 volts, protecting the cable from physical damage .
, Question 6
An applicant for the New Mexico EE-98 Electrical Contractor license must document a minimum of
how many hours of journeyman electrical experience?
A. 4,000 hours
B. 6,000 hours
C. 8,000 hours
D. 10,000 hours
🟢 Correct answer: C
🔴 Explanation: The EE-98 license requires four years or 8,000 hours of documented journeyman
electrical experience within the previous ten years .
Question 7
Which NEC Article covers grounding and bonding requirements?
A. Article 210
B. Article 220
C. Article 240
D. Article 250
🟢 Correct answer: D
🔴 Explanation: NEC Article 250 contains the general requirements for grounding and bonding of
electrical systems and equipment .
Question 8
The EE-98 license authorizes electrical work up to what nominal voltage?
A. 120 volts
B. 240 volts
C. 600 volts
