NICET Electrical Power Testing (EPT) Level I
Certification Exam | Latest Verified Questions and
Detailed Answers
OVERVIEW DESCRIPTION:
This Comprehensive set of multiple choice questions is designed for the NICET Electrical
Power Testing (EPT) Level I exam, a computer-based assessment that evaluates entry-level
technicians on fundamental electrical safety and basic field testing practices under
supervision. Delivered through Pearson VUE testing centers or online proctoring, the exam
focuses on core topics including lockout/tagout and personal protective equipment,
identification and connection of basic test instruments, electrical theory and Ohm's law
calculations, and applicable industry standards from OSHA (29 CFR 1910 and 1926) and
NFPA 70E. The examination is administered by the National Institute for Certification in
Engineering Technologies (NICET).
QUESTION 1
What is the primary purpose of a lockout/tagout (LOTO) program?
A. To increase production efficiency
B. To prevent the unexpected energization or startup of equipment during service
C. To identify qualified electrical workers
D. To document daily work assignments
CORRECT ANSWER: B. To prevent the unexpected energization or startup of equipment
during service
EXPERT RATIONALE: LOTO ensures hazardous energy is controlled so that equipment
cannot be inadvertently powered on while being serviced, protecting personnel from
electrocution or injury.
QUESTION 2
According to OSHA, who is permitted to install a lockout device on energized electrical

equipment?
A. Any employee who feels it is necessary
B. Only a qualified person
C. Only an authorized employee
D. The site safety manager exclusively
CORRECT ANSWER: C. Only an authorized employee
EXPERT RATIONALE: Authorized employees are specifically trained and designated to
apply lockout/tagout devices, understanding the energy control procedures and
associated hazards.
QUESTION 3
What is the correct sequence for the fire extinguisher P-A-S-S method?
A. Pull, Aim, Squeeze, Sweep
B. Push, Aim, Squeeze, Sweep
C. Pull, Activate, Squeeze, Sweep
D. Pinch, Aim, Squeeze, Sweep
CORRECT ANSWER: A. Pull, Aim, Squeeze, Sweep
EXPERT RATIONALE: P-A-S-S stands for Pull the pin, Aim at the base of the fire, Squeeze
the handle, Sweep side to side; this is the standard technique for portable fire
extinguishers.
QUESTION 4
A Class C fire involves:
A. Ordinary combustibles like wood and paper
B. Flammable liquids
C. Energized electrical equipment
,3|Page
D. Combustible metals
CORRECT ANSWER: C. Energized electrical equipment
EXPERT RATIONALE: Class C fires involve live electrical circuits; using a non-conductive
extinguishing agent is critical to avoid shock hazards.
QUESTION 5
Which NFPA standard specifically addresses electrical safety in the workplace?
A. NFPA 70
B. NFPA 70E
C. NFPA 72
D. NFPA 101
CORRECT ANSWER: B. NFPA 70E
EXPERT RATIONALE: NFPA 70E is the Standard for Electrical Safety in the Workplace,
providing guidance on shock and arc flash hazard assessment and safe work practices.
QUESTION 6
What does an arc-rated faceshield protect against during electrical testing?
A. Falling objects
B. Chemical splashes
C. Arc flash thermal energy and flying debris
D. Inhalation of toxic gases
CORRECT ANSWER: C. Arc flash thermal energy and flying debris
EXPERT RATIONALE: Arc-rated face protection shields the face from intense heat and
molten metal spray produced by an arc flash event.
QUESTION 7
When using a multimeter to measure voltage, the test leads are connected in:
, 4|Page
A. Series with the circuit
B. Parallel with the component or circuit
C. Series with the power source only
D. Any connection configuration
CORRECT ANSWER: B. Parallel with the component or circuit
EXPERT RATIONALE: Voltmeters must be placed in parallel to measure the potential
difference across two points without significantly altering the circuit.
QUESTION 8
A technician needs to verify a circuit is de-energized before starting work. The most
reliable method is:
A. Using a non-contact voltage tester and then testing it on a known live source
B. Trusting the equipment disconnect switch position
C. Relying on a coworker’s verbal confirmation
D. Checking the breaker panel label only
CORRECT ANSWER: A. Using a non-contact voltage tester and then testing it on a
known live source
EXPERT RATIONALE: A live-dead-live check verifies the tester is functioning before and
after the measurement, ensuring no voltage is present.
QUESTION 9
In NFPA 70E, a qualified person is defined as one who:
A. Holds an engineering degree
B. Has skills and knowledge related to the construction and operation of electrical
equipment and has received safety training to recognize and avoid hazards
C. Has at least 10 years of experience
D. Is a licensed electrician
