CFESA ELECTRICAL PRACTICE TEST 2026 200 PRACTICE QUESTIONS | VERIFIED
ANSWERS & DETAILED RATIONALES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• This comprehensive practice test contains 200 expertly crafted questions
designed to assess your mastery of electrical safety protocols, hazard recognition,
and compliance standards essential for CFESA certification.
• Study strategically by reviewing detailed rationales for each answer, focusing on
areas of weakness, and revisiting questions to reinforce critical safety concepts
before your certification exam.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Question 1: What is the primary purpose of lockout/tagout (LOTO) procedures
in electrical work?
A) To reduce paperwork and documentation requirements
B) To prevent accidental startup of equipment during maintenance or repair
C) To speed up the repair process
D) To reduce training costs for employees
E) To comply with local utility company preferences
✓ CORRECT ANSWER: B) To prevent accidental startup of equipment during
maintenance or repair
RATIONALE: LOTO procedures are critical safety protocols designed to isolate and
render inoperative electrical and mechanical equipment to prevent unexpected
startup that could cause serious injury or death. This is a foundational principle of
electrical safety and a requirement under OSHA 1910.147. Options A, C, D, and E do
,not represent the actual purpose of LOTO—while compliance and documentation
may result, the primary purpose is worker protection.

Question 2: Which NFPA standard is most directly applicable to electrical
worker safety?
A) NFPA 30
B) NFPA 54
C) NFPA 70E
D) NFPA 99
E) NFPA 110
✓ CORRECT ANSWER: C) NFPA 70E
RATIONALE: NFPA 70E is the Standard for Electrical Safety in the Workplace and is
the primary reference for electrical worker safety practices. It covers electrical
safety principles, hazard analysis, work practices, PPE requirements, and safe work
procedures. While other NFPA standards address specific equipment or
applications, 70E is the overarching standard for worker protection in electrical
environments.

Question 3: Arc flash hazard analysis must be performed on electrical
equipment that operates at what minimum voltage?
A) 50 volts
B) 110 volts
C) 208 volts
D) 600 volts
E) 1000 volts
,✓ CORRECT ANSWER: A) 50 volts
RATIONALE: According to NFPA 70E, arc flash hazard analysis is required for all
electrical equipment that operates at 50 volts or higher. This includes both single-
phase and three-phase systems. The hazard analysis helps determine arc flash
boundaries and required PPE. Ignoring equipment below this threshold would miss
significant hazards.

Question 4: What is the maximum approach distance an unqualified person
can maintain from live electrical equipment at 480 volts AC?
A) 1 foot
B) 3 feet
C) 5 feet
D) 10 feet
E) Unqualified persons are not permitted near any live electrical equipment
✓ CORRECT ANSWER: E) Unqualified persons are not permitted near any live
electrical equipment
RATIONALE: OSHA and NFPA 70E strictly prohibit unqualified persons from working
on or approaching energized electrical equipment. Only qualified individuals with
proper training, certification, and equipment are permitted to work near or on live
electrical systems. The approach distances specified in safety standards apply only
to qualified workers wearing appropriate PPE.

Question 5: What must be done before attempting to rescue an electrical
shock victim?
A) Immediately move the victim to a safe location
, B) Ensure the victim is no longer in contact with the electrical source and that you
are protected from electrical hazards
C) Begin CPR immediately
D) Call for an ambulance only
E) Check the victim's pulse first
✓ CORRECT ANSWER: B) Ensure the victim is no longer in contact with the
electrical source and that you are protected from electrical hazards
RATIONALE: The first priority in electrical rescue is to ensure your own safety while
removing the victim from the electrical hazard. This may involve de-energizing the
circuit, using a non-conductive object to move the victim, or positioning yourself
safely. Only after the victim is safely removed and you are protected should rescue
breathing or CPR be initiated. Attempting rescue while still in contact with the
electrical source will create additional victims.

Question 6: Which type of personal protective equipment is most critical
when working on energized equipment?
A) Hard hats
B) Electrical PPE rated for the voltage and arc flash hazard
C) Work gloves
D) Safety glasses
E) Steel-toed boots
✓ CORRECT ANSWER: B) Electrical PPE rated for the voltage and arc flash
hazard
RATIONALE: When working on energized electrical equipment, the most critical PPE
includes voltage-rated gloves, insulated tools, and arc-rated clothing (jacket, pants,
face shield, and hood). This PPE must be rated for the specific voltage and arc flash
