,Question 1
A maintenance electrician needs to open a 480V motor control center (MCC) bucket to replace a
starter. The available fault current is 65 kA, and the clearing time is 0.1 seconds. Using the 2025
NFPA 70E Table 130.5(C) (Arc Flash Risk Assessment), which approach is required to determine if
an arc flash hazard exists?
A) Conduct an incident energy analysis per 130.5(H) using the IEEE 1584 formulas.
B) Use the arc flash PPE category method from Table 130.7(C)(15)(a) based on equipment type and
parameters.
C) Assume an arc flash hazard exists for all equipment operating at 50V or more.
D) Perform a shock risk assessment only, as arc flash is not a concern for MCCs at 480V.
Answer: A) Conduct an incident energy analysis per 130.5(H) using the IEEE 1584 formulas.
Explanation: Table 130.5(C) provides conditions for when an arc flash hazard exists but does not
eliminate the need for an incident energy analysis. For equipment with available fault
current "e 40 kA and clearing time "e 0.1 s, an incident energy analysis is required per
130.5(H). Option B is incorrect because the table method is for equipment not
exceeding certain parameters; here fault current exceeds typical thresholds. Option C is
too broad; the standard requires a documented risk assessment. Option D ignores arc
flash hazards.
Question 2
An electrical safety program requires that all employees exposed to electrical hazards be trained.
Per NFPA 70E 2025, Section 110.2, which of the following training elements must be documented
and retrained at intervals not to exceed three years?
A) First aid and CPR training
B) Emergency response procedures for electrical incidents
C) Risk assessment procedures and use of the hierarchy of controls
D) All of the above
Answer: C) Risk assessment procedures and use of the hierarchy of controls
Explanation: Section 110.2(D)(2) requires retraining on risk assessment and hazard identification at
least every three years. First aid/CPR (A) and emergency response (B) are important but
not specifically required to be retrained at three-year intervals under this section; they
may have separate requirements. Option D is too broad. The core requirement is
documented training on risk assessment procedures.

,Question 3
A facility has a 13.8 kV switchgear lineup. Per Table 130.4(D)(a) of the 2025 NFPA 70E, what is the
limited approach boundary (with an exposed fixed circuit part) for a qualified person if the system
voltage is 13.8 kV?
A) 0.1 m (4 in.)
B) 0.2 m (8 in.)
C) 0.7 m (2 ft 4 in.)
D) 1.2 m (4 ft 0 in.)
Answer: C) 0.7 m (2 ft 4 in.)
Explanation: Table 130.4(D)(a) gives the limited approach boundary for exposed fixed circuit parts
for nominal voltage 13.8 kV (range 7.2–15 kV) as 0.7 m (2 ft 4 in.). Option A is for
50–300 V. Option B is for 301–750 V. Option D is for 15.1–36 kV. The correct
boundary is based on voltage and whether the part is fixed or movable.
Question 4
An arc flash risk assessment determined that a specific panel has an incident energy of 12 cal/cm².
Per Table 130.7(C)(15)(c) (Arc Flash PPE Categories), what is the minimum arc rating (ATPV or
EBT) required for the outer layer of clothing?
A) 4 cal/cm²
B) 8 cal/cm²
C) 12 cal/cm²
D) 25 cal/cm²
Answer: C) 12 cal/cm²
Explanation: When incident energy is known, the required arc rating of clothing must be at least the
incident energy level. For 12 cal/cm², the clothing must have an arc rating "e 12 cal/cm².
Option A and B are lower than the incident energy. Option D is higher than necessary
but acceptable; however, the minimum is the incident energy value. The standard
requires that PPE be selected based on incident energy analysis or the category method.

, Question 5
An energized electrical work permit is required per Section 130.2(B) of NFPA 70E 2025. Which of
the following conditions would allow an exception to the permit requirement?
A) Work is performed on equipment operating at less than 50V.
B) The task is performed by a qualified person using appropriate PPE.
C) Work involves only testing, troubleshooting, and voltage measurement.
D) The equipment is in an electrically safe work condition.
Answer: C) Work involves only testing, troubleshooting, and voltage measurement.
Explanation: Section 130.2(B)(1) lists exceptions: testing, troubleshooting, and voltage measurement
do not require an energized work permit, provided other safety measures are in place.
Option A is not a blanket exception; voltage alone does not eliminate hazards. Option B
is incorrect because qualified persons still need a permit unless an exception applies.
Option D describes a de-energized state, which is not energized work.
Question 6
Per Section 205.3 of NFPA 70E 2025, which of the following is a required element of an electrical
safety program's risk assessment procedure?
A) Job safety planning and briefing before each task
B) Use of the hierarchy of risk control methods (elimination, substitution, engineering controls, etc.)
C) A written procedure for each electrical task performed
D) Annual inspection of all electrical PPE
Answer: B) Use of the hierarchy of risk control methods (elimination, substitution, engineering
controls, etc.)
Explanation: Section 205.3 requires that the risk assessment procedure incorporate the hierarchy of
risk control methods. Option A is a separate requirement (job briefing, Section 110.4).
Option C is not required for every task; only high-risk tasks may need written
procedures. Option D is an equipment maintenance requirement, not a risk assessment
procedure element.
