NEW MEXICO EE-98 RESIDENTIAL AND
COMMERCIAL ELECTRICAL EXAMINATION
TEST 2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉ Conductors with THWN, THHW, and THW insulation. Answer:
Recognized for use in dry and wet locations.
◉ Minimum size aluminum THW conductors for service-entrance.
Answer: For a demand load of 200 amperes, the minimum size
required is 4/0 AWG.
◉ Ampacity calculation for service-entrance conductors. Answer:
200 amperes x 83% = 166 amperes.
◉ Full-load current rating of a 150 kVA transformer. Answer:
Calculated using I = (150 kVA x 1000) / 240 volts = 625 amperes.
◉ Standard ampere ratings for circuit breakers. Answer: A circuit
breaker with an ampere rating of 75 amperes is not a standard
ampere rating.
, ◉ Minimum length of free conductor at junction box. Answer: At
least 6 inches of free conductor is to be left at each junction box.
◉ Minimum size for overhead service-drop conductors. Answer:
Shall not be smaller than 8 AWG copper or 6 AWG aluminum.
◉ Installation height for galvanized eye-bolt. Answer: The eye-bolt
must be installed not less than 10 ft. above finished grade.
◉ Purpose of electrical continuity for metallic conduit. Answer: To
ensure a continuous path for grounding and to prevent shock
hazards.
◉ Service-entrance conductors. Answer: Conductors from the
service point from the utility company to the service disconnecting
means.
◉ Overhead conductors. Answer: Conductors between the utility
electric supply system and the service point.
◉ Section 310.15(B)(7)(1). Answer: Permits one-family dwelling
service-entrance conductors to be sized at an ampacity of not less
than 83% of the service rating.
