LATEST ELECTRICAL POWER TESTING (EPT)
CERTIFICATION EXAM OFFERED BY NICET |
Q&A WITH RATIONALES
1. What is the minimum voltage threshold for
establishing an electrically safe work condition
before an employee works on or near exposed
conductors?
A) 30 V
B) 50 V
C) 120 V
D) 240 V
Correct answer: B
Rationale: NFPA 70E requires an electrically safe
work condition for any work on exposed parts
operating at 50 V or more, subject to specific
exceptions. (Source: NFPA 70E 2024, Article
110.2(A))
2. Which of the following is NOT an acceptable
justification for performing energized electrical
work?
,A) Troubleshooting that requires the equipment to
be energized
B) Testing that requires the equipment to be
energized
C) Production schedule pressure
D) Infeasibility due to equipment design
Correct answer: C
Rationale: NFPA 70E 130.2(A) lists infeasibility,
troubleshooting, and testing as permissible
justifications. Production loss or schedule pressure
is not an acceptable justification. (Source: NFPA 70E
130.2(A))
3. What is the primary purpose of the
“Live‑Dead‑Live” test?
A) To determine the capacity of a battery
B) To measure the resistance of a ground rod
C) To verify that a circuit is de‑energized
D) To calculate the phase rotation
Correct answer: C
Rationale: NFPA 70E 120.5(7) requires the test
instrument to be verified on a known live source,
,then tested on the de‑energized part, and then
re‑tested on the live source (Live‑Dead‑Live) to
confirm the circuit is de‑energized. (Source: NFPA
70E 120.5(7))
4. A Level I Electrical Power Testing technician is
required to work under what level of supervision?
A) No supervision
B) General supervision
C) Direct supervision
D) Remote supervision only
Correct answer: C
Rationale: The NICET EPT Level I technician works
under the direct supervision of a higher‑level
technician. (Source: NICET Electrical Power Testing
Content Outline, Level I)
5. Which instrument is primarily used to measure
insulation resistance in megohms?
A) Digital multimeter
B) Low‑resistance ohmmeter (DLRO)
C) Megger (insulation resistance tester)
, D) Voltage detector pen
Correct answer: C
Rationale: A Megger applies a high DC voltage and
measures the resulting resistance in megohms to
evaluate insulation condition. (Source: NICET EPT
Level I Ultimate Exam)
6. A Level II Electrical Power Testing technician is
expected to work under what level of supervision?
A) Direct supervision only
B) General supervision
C) No supervision
D) Remote supervision only
Correct answer: B
Rationale: The Level II technician isolates and
grounds power equipment, connects test
equipment, and performs standard tests under
general supervision. (Source: NICET Electrical
