QUESTIONS WITH VERIFIED ANSWERS & DETAILED
RATIONALES (REVISED FOR NFPA 70E-2026 |
GUARANTEED PASS A+) - 150 Questions
Section 1: General (Questions 1-150)
1 A facility manager argues that because all electrical equipment is de-energized and locked out/tagged out, an
Electrically Safe Work Condition (ESWC) exists, and therefore no shock or arc flash risk assessment is required.
Which of the following best evaluates this claim under NFPA 70E-2026?
A) The claim is correct; de-energization eliminates all electrical hazards, so risk assessments are unnecessary.
B) The claim is incorrect because stored energy (e.g., capacitors) may still present a shock hazard even after
de-energization.
C) The claim is incorrect because the presence of test instruments or temporary grounds can introduce new
hazards requiring assessment.
D) The claim is partially correct; arc flash risk assessment is not needed, but shock risk assessment is still
required.
Answer: C
Rationale: NFPA 70E-2026 requires a risk assessment even when an ESWC is claimed, because the process of
verifying de-energization (e.g., using test instruments) or applying temporary grounding can introduce hazards.
Options A and B are incomplete; option D is false because both shock and arc flash risks must be assessed if any
hazard remains.
2 An electrical safety program requires that all employees who might be exposed to electrical hazards receive
training. Under NFPA 70E-2026, which of the following best defines the minimum training content for
'qualified persons'?
A) Training on the use of voltage testers and lockout/tagout procedures only.
B) Training on the skills and techniques necessary to distinguish exposed energized parts from other parts, and
on the use of precautionary techniques and PPE.
C) Training on emergency response procedures and first aid for electrical shock.
D) Training on the company's electrical safety program and the location of the NFPA 70E standard.
Answer: B
Rationale: NFPA 70E-2026 Section 110.2(A)(1) specifies that qualified persons must be trained to identify exposed
energized parts, understand the hazards, and know the safe work practices and PPE required. Option A is too
narrow; option C is important but not the primary definition; option D is insufficient for qualification.
3 During an arc flash risk assessment, the incident energy at a panel is calculated to be 12 cal/cm² at 18 inches.
The employer selects a PPE category method instead of the incident energy analysis. Which of the following is
a correct requirement under NFPA 70E-2026 for this scenario?
A) The employer may use the PPE category method only if the available fault current is less than 10 kA.
B) The employer must use the incident energy analysis because the calculated incident energy exceeds 8 cal/cm².
C) The employer may use the PPE category method, but must ensure that the PPE selected has an arc rating at
least equal to the calculated incident energy.
,D) The employer must use the PPE category method because the incident energy analysis is optional.
Answer: C
Rationale: NFPA 70E-2026 allows either the incident energy analysis or the PPE category method, but if the
category method is used, the selected PPE must have an arc rating at least equal to the calculated incident energy
(Table 130.5(G)). Option A is false; option B is false because the category method can still be used; option D is
false because the incident energy analysis is also permissible.
4 A risk assessment identifies a shock hazard with a voltage of 480 V and a limited approach boundary of 42
inches. A qualified worker needs to perform a task that involves crossing the restricted approach boundary.
Which of the following is required by NFPA 70E-2026?
A) The worker must wear voltage-rated gloves and have a written energized work permit.
B) The worker must be accompanied by a safety observer and use insulated tools.
C) The worker must wear arc-rated clothing and a face shield.
D) The worker must complete a job safety plan and obtain an energized work permit if the task is not justified by
the exception.
Answer: D
Rationale: NFPA 70E-2026 requires an energized electrical work permit when work is performed within the
restricted approach boundary, unless an exception applies (e.g., testing, troubleshooting that does not increase risk).
Option A is partially correct but the permit is required; option B is a good practice but not the primary requirement;
option C addresses arc flash, not shock.
5 An employer's electrical safety program includes a hierarchy of risk controls. Which of the following correctly
sequences the hierarchy from most effective to least effective as per NFPA 70E-2026?
A) Engineering controls, administrative controls, awareness, PPE
B) Elimination, substitution, engineering controls, administrative controls, PPE
C) PPE, administrative controls, engineering controls, elimination
D) Substitution, elimination, engineering controls, PPE, administrative controls
Answer: B
Rationale: NFPA 70E-2026 adopts the standard hierarchy of controls: elimination (e.g., de-energizing) is most
effective, followed by substitution (e.g., using lower voltage), engineering controls (e.g., guarding), administrative
controls (e.g., procedures), and PPE (least effective). Option A misses elimination and substitution; options C and
D reverse the order.
6 During an incident investigation, it is found that a worker received a shock because the voltage detector used did
not indicate presence of voltage. The investigation team must determine root causes. Which of the following is
the most appropriate next step under NFPA 70E-2026?
A) Replace the voltage detector with a newer model.
B) Retrain the worker on proper voltage testing procedures.
C) Evaluate the adequacy of the inspection and maintenance program for test instruments.
D) Update the lockout/tagout procedures to require a second test.
Answer: C
Rationale: NFPA 70E-2026 requires that test instruments be inspected and maintained according to manufacturer's
instructions. The root cause may be a defective instrument, so the investigation should evaluate the maintenance
program. Options A and B are reactive but do not address systemic issues; option D may be premature without
understanding why the detector failed.
,7 An electrical safety program mandates that all employees wear arc-rated clothing when exposed to an arc flash
hazard. However, a contractor argues that their employees are only performing a visual inspection and are not
approaching the equipment. Under NFPA 70E-2026, which of the following is correct?
A) The contractor's employees must wear arc-rated clothing because they are in the arc flash boundary.
B) The contractor's employees are not required to wear arc-rated clothing if they remain outside the limited
approach boundary.
C) The contractor's employees must wear arc-rated clothing only if the incident energy exceeds 1.2 cal/cm².
D) The contractor's employees need not wear arc-rated clothing if the visual inspection is performed from outside
the arc flash boundary.
Answer: D
Rationale: NFPA 70E-2026 requires arc-rated clothing only when there is a risk of arc flash exposure. If the visual
inspection is performed from outside the arc flash boundary (as determined by the risk assessment), no arc-rated
clothing is needed. Option A is false because the arc flash boundary must be crossed; option B confuses shock
boundaries; option C is false because the boundary is based on incident energy, but if outside, no PPE is required.
8 A qualified person is using a hot stick to operate a disconnect switch. The task is considered 'normal operation'
of equipment that is in good condition. Which of the following correctly describes the shock protection
requirements under NFPA 70E-2026?
A) No shock hazard exists because the hot stick provides insulation.
B) The worker must wear voltage-rated gloves because the restricted approach boundary is crossed.
C) The worker is not required to wear voltage-rated gloves if the equipment is properly maintained and the hot
stick is rated for the voltage.
D) The worker must wear voltage-rated gloves and a face shield because the arc flash boundary may be crossed.
Answer: C
Rationale: NFPA 70E-2026 allows 'normal operation' of equipment in good condition without additional PPE if the
equipment is properly maintained and the worker uses appropriate tools (e.g., hot stick). The hot stick provides
insulation, so crossing the restricted approach boundary with an insulated tool does not require voltage-rated
gloves. Option A is partially correct but not complete; option B is false because the hot stick eliminates the need
for gloves; option D addresses arc flash, not shock.
9 An electrical safety program includes a policy that all electrical incidents must be reported within 24 hours.
During an investigation of a near-miss event, the team discovers that a worker bypassed a safety interlock to
troubleshoot a machine. Which of the following is the most critical finding for preventing recurrence?
A) The worker did not have the required training on interlock bypass procedures.
B) The worker was under time pressure to restore production.
C) The safety interlock was not designed to be easily bypassed without tools.
D) The worker failed to use the appropriate lockout/tagout procedure.
Answer: A
Rationale: NFPA 70E-2026 emphasizes that only qualified persons may bypass safety interlocks after a risk
assessment. The root cause is likely lack of training on the specific procedure. Option B is a contributing factor but
not the most critical; option C is a design issue but may not be the primary cause; option D is a symptom of the
bypass, but the training deficiency is more fundamental.
10 An employer's risk assessment for a task involving exposure to 277 V determines that the shock risk is 'low'
due to the use of insulated tools and rubber matting. Under NFPA 70E-2026, which of the following is true
regarding the requirement for an energized electrical work permit?
A) A permit is required because the voltage exceeds 120 V.
, B) A permit is required because the task involves crossing the limited approach boundary.
C) A permit is required only if the task is not considered 'normal operation' of the equipment.
D) A permit is not required because the risk is low and the task is justified.
Answer: B
Rationale: NFPA 70E-2026 requires an energized electrical work permit when work is performed within the limited
approach boundary, regardless of the risk level, unless an exception applies (e.g., testing, troubleshooting that does
not increase risk). Option A is false because voltage alone does not determine permit need; option C is false
because 'normal operation' is an exception only if the equipment is in good condition; option D is false because low
risk does not eliminate the permit requirement.
11 A facility's electrical safety program requires an annual review of all energized electrical work permits
(EEWPs). During the review, the safety manager notes that several permits were issued for tasks where the
nominal system voltage was 120V AC and the available fault current was 10 kA. According to NFPA
70E-2026, which of the following is the primary criterion for determining whether an EEWP is required for a
task?
A) The voltage level alone, with any voltage above 50V requiring an EEWP
B) The presence of an electrical hazard, regardless of voltage or energy level
C) The task being performed on equipment with exposed energized parts operating at 50V or more
D) The estimated incident energy exceeding 1.2 cal/cm² at the working distance
Answer: C
Rationale: NFPA 70E-2026 requires an energized electrical work permit for work on exposed energized electrical
conductors or circuit parts operating at 50 volts or more. Voltage alone is not the only factor; the permit is tied to
exposure to energized parts. Option A is incorrect because 50V is the threshold, not 120V. Option D is incorrect
because the permit is required before incident energy analysis, not based on its result. Option B is too vague.
12 In a facility with a 480V, 3-phase system, a qualified electrical worker is tasked with replacing a circuit breaker
in a panelboard. The worker uses a voltage tester rated for 1000V and verifies the absence of voltage at the line
terminals. However, the worker does not test phase-to-phase or phase-to-ground on all conductors. Which
NFPA 70E-2026 requirement has been violated?
A) The voltage tester must be rated for the maximum system voltage, which is 480V, so 1000V is acceptable
B) The absence of voltage verification must be performed on each phase conductor and phase-to-phase and
phase-to-ground
C) The verification must be performed using a contact-type tester only; non-contact testers are prohibited
D) The worker must also verify the tester functions properly on a known voltage source before and after testing
Answer: B
Rationale: NFPA 70E-2026 Section 120.5 requires that absence of voltage be verified on each phase conductor and
phase-to-phase and phase-to-ground. The worker only tested line terminals, not all combinations. Option A is
irrelevant; tester rating is not the issue. Option C is false; non-contact testers are allowed if they meet requirements.
Option D is a requirement but not the violation described.
13 During an arc flash risk assessment for a 208V panel, the incident energy is calculated to be 0.8 cal/cm² at the
working distance. The panel is fed from a transformer with a 5% impedance. According to NFPA 70E-2026,
which of the following is the minimum arc flash PPE category required for working on this panel with exposed
energized parts?
A) Category 0 (N/A) - no PPE required because incident energy is below 1.2 cal/cm²
B) Category 1 - because the voltage is above 50V and work is on energized parts
C) Category 0 (N/A) - but the worker must still wear non-arc-rated clothing

RATIONALES (REVISED FOR NFPA 70E-2026 |
GUARANTEED PASS A+) - 150 Questions
Section 1: General (Questions 1-150)
1 A facility manager argues that because all electrical equipment is de-energized and locked out/tagged out, an
Electrically Safe Work Condition (ESWC) exists, and therefore no shock or arc flash risk assessment is required.
Which of the following best evaluates this claim under NFPA 70E-2026?
A) The claim is correct; de-energization eliminates all electrical hazards, so risk assessments are unnecessary.
B) The claim is incorrect because stored energy (e.g., capacitors) may still present a shock hazard even after
de-energization.
C) The claim is incorrect because the presence of test instruments or temporary grounds can introduce new
hazards requiring assessment.
D) The claim is partially correct; arc flash risk assessment is not needed, but shock risk assessment is still
required.
Answer: C
Rationale: NFPA 70E-2026 requires a risk assessment even when an ESWC is claimed, because the process of
verifying de-energization (e.g., using test instruments) or applying temporary grounding can introduce hazards.
Options A and B are incomplete; option D is false because both shock and arc flash risks must be assessed if any
hazard remains.
2 An electrical safety program requires that all employees who might be exposed to electrical hazards receive

energized parts, understand the hazards, and know the safe work practices and PPE required. Option A is too
narrow; option C is important but not the primary definition; option D is insufficient for qualification.
3 During an arc flash risk assessment, the incident energy at a panel is calculated to be 12 cal/cm² at 18 inches.
The employer selects a PPE category method instead of the incident energy analysis. Which of the following is
a correct requirement under NFPA 70E-2026 for this scenario?
A) The employer may use the PPE category method only if the available fault current is less than 10 kA.
B) The employer must use the incident energy analysis because the calculated incident energy exceeds 8 cal/cm².
C) The employer may use the PPE category method, but must ensure that the PPE selected has an arc rating at
least equal to the calculated incident energy.
,D) The employer must use the PPE category method because the incident energy analysis is optional.
Answer: C
Rationale: NFPA 70E-2026 allows either the incident energy analysis or the PPE category method, but if the
category method is used, the selected PPE must have an arc rating at least equal to the calculated incident energy
(Table 130.5(G)). Option A is false; option B is false because the category method can still be used; option D is
false because the incident energy analysis is also permissible.
4 A risk assessment identifies a shock hazard with a voltage of 480 V and a limited approach boundary of 42
inches. A qualified worker needs to perform a task that involves crossing the restricted approach boundary.
Which of the following is required by NFPA 70E-2026?
A) The worker must wear voltage-rated gloves and have a written energized work permit.
B) The worker must be accompanied by a safety observer and use insulated tools.
C) The worker must wear arc-rated clothing and a face shield.
D) The worker must complete a job safety plan and obtain an energized work permit if the task is not justified by
the exception.
Answer: D
Rationale: NFPA 70E-2026 requires an energized electrical work permit when work is performed within the
restricted approach boundary, unless an exception applies (e.g., testing, troubleshooting that does not increase risk).
Option A is partially correct but the permit is required; option B is a good practice but not the primary requirement;
option C addresses arc flash, not shock.
5 An employer's electrical safety program includes a hierarchy of risk controls. Which of the following correctly
sequences the hierarchy from most effective to least effective as per NFPA 70E-2026?
A) Engineering controls, administrative controls, awareness, PPE
B) Elimination, substitution, engineering controls, administrative controls, PPE
C) PPE, administrative controls, engineering controls, elimination
D) Substitution, elimination, engineering controls, PPE, administrative controls
Answer: B
Rationale: NFPA 70E-2026 adopts the standard hierarchy of controls: elimination (e.g., de-energizing) is most
effective, followed by substitution (e.g., using lower voltage), engineering controls (e.g., guarding), administrative
controls (e.g., procedures), and PPE (least effective). Option A misses elimination and substitution; options C and
D reverse the order.
6 During an incident investigation, it is found that a worker received a shock because the voltage detector used did
not indicate presence of voltage. The investigation team must determine root causes. Which of the following is
the most appropriate next step under NFPA 70E-2026?
A) Replace the voltage detector with a newer model.
B) Retrain the worker on proper voltage testing procedures.
C) Evaluate the adequacy of the inspection and maintenance program for test instruments.
D) Update the lockout/tagout procedures to require a second test.
Answer: C
Rationale: NFPA 70E-2026 requires that test instruments be inspected and maintained according to manufacturer's
instructions. The root cause may be a defective instrument, so the investigation should evaluate the maintenance
program. Options A and B are reactive but do not address systemic issues; option D may be premature without
understanding why the detector failed.
,7 An electrical safety program mandates that all employees wear arc-rated clothing when exposed to an arc flash
hazard. However, a contractor argues that their employees are only performing a visual inspection and are not
approaching the equipment. Under NFPA 70E-2026, which of the following is correct?
A) The contractor's employees must wear arc-rated clothing because they are in the arc flash boundary.
B) The contractor's employees are not required to wear arc-rated clothing if they remain outside the limited
approach boundary.
C) The contractor's employees must wear arc-rated clothing only if the incident energy exceeds 1.2 cal/cm².
D) The contractor's employees need not wear arc-rated clothing if the visual inspection is performed from outside
the arc flash boundary.
Answer: D
Rationale: NFPA 70E-2026 requires arc-rated clothing only when there is a risk of arc flash exposure. If the visual
inspection is performed from outside the arc flash boundary (as determined by the risk assessment), no arc-rated
clothing is needed. Option A is false because the arc flash boundary must be crossed; option B confuses shock
boundaries; option C is false because the boundary is based on incident energy, but if outside, no PPE is required.
8 A qualified person is using a hot stick to operate a disconnect switch. The task is considered 'normal operation'
of equipment that is in good condition. Which of the following correctly describes the shock protection
requirements under NFPA 70E-2026?
A) No shock hazard exists because the hot stick provides insulation.
B) The worker must wear voltage-rated gloves because the restricted approach boundary is crossed.
C) The worker is not required to wear voltage-rated gloves if the equipment is properly maintained and the hot
stick is rated for the voltage.
D) The worker must wear voltage-rated gloves and a face shield because the arc flash boundary may be crossed.
Answer: C
Rationale: NFPA 70E-2026 allows 'normal operation' of equipment in good condition without additional PPE if the
equipment is properly maintained and the worker uses appropriate tools (e.g., hot stick). The hot stick provides
insulation, so crossing the restricted approach boundary with an insulated tool does not require voltage-rated
gloves. Option A is partially correct but not complete; option B is false because the hot stick eliminates the need
for gloves; option D addresses arc flash, not shock.
9 An electrical safety program includes a policy that all electrical incidents must be reported within 24 hours.
During an investigation of a near-miss event, the team discovers that a worker bypassed a safety interlock to
troubleshoot a machine. Which of the following is the most critical finding for preventing recurrence?
A) The worker did not have the required training on interlock bypass procedures.
B) The worker was under time pressure to restore production.
C) The safety interlock was not designed to be easily bypassed without tools.
D) The worker failed to use the appropriate lockout/tagout procedure.
Answer: A
Rationale: NFPA 70E-2026 emphasizes that only qualified persons may bypass safety interlocks after a risk
assessment. The root cause is likely lack of training on the specific procedure. Option B is a contributing factor but
not the most critical; option C is a design issue but may not be the primary cause; option D is a symptom of the
bypass, but the training deficiency is more fundamental.
10 An employer's risk assessment for a task involving exposure to 277 V determines that the shock risk is 'low'
due to the use of insulated tools and rubber matting. Under NFPA 70E-2026, which of the following is true
regarding the requirement for an energized electrical work permit?
A) A permit is required because the voltage exceeds 120 V.
, B) A permit is required because the task involves crossing the limited approach boundary.
C) A permit is required only if the task is not considered 'normal operation' of the equipment.
D) A permit is not required because the risk is low and the task is justified.
Answer: B
Rationale: NFPA 70E-2026 requires an energized electrical work permit when work is performed within the limited
approach boundary, regardless of the risk level, unless an exception applies (e.g., testing, troubleshooting that does
not increase risk). Option A is false because voltage alone does not determine permit need; option C is false
because 'normal operation' is an exception only if the equipment is in good condition; option D is false because low
risk does not eliminate the permit requirement.
11 A facility's electrical safety program requires an annual review of all energized electrical work permits
(EEWPs). During the review, the safety manager notes that several permits were issued for tasks where the
nominal system voltage was 120V AC and the available fault current was 10 kA. According to NFPA
70E-2026, which of the following is the primary criterion for determining whether an EEWP is required for a
task?
A) The voltage level alone, with any voltage above 50V requiring an EEWP
B) The presence of an electrical hazard, regardless of voltage or energy level
C) The task being performed on equipment with exposed energized parts operating at 50V or more
D) The estimated incident energy exceeding 1.2 cal/cm² at the working distance
Answer: C
Rationale: NFPA 70E-2026 requires an energized electrical work permit for work on exposed energized electrical
conductors or circuit parts operating at 50 volts or more. Voltage alone is not the only factor; the permit is tied to
exposure to energized parts. Option A is incorrect because 50V is the threshold, not 120V. Option D is incorrect
because the permit is required before incident energy analysis, not based on its result. Option B is too vague.
12 In a facility with a 480V, 3-phase system, a qualified electrical worker is tasked with replacing a circuit breaker
in a panelboard. The worker uses a voltage tester rated for 1000V and verifies the absence of voltage at the line
terminals. However, the worker does not test phase-to-phase or phase-to-ground on all conductors. Which
NFPA 70E-2026 requirement has been violated?
A) The voltage tester must be rated for the maximum system voltage, which is 480V, so 1000V is acceptable
B) The absence of voltage verification must be performed on each phase conductor and phase-to-phase and
phase-to-ground
C) The verification must be performed using a contact-type tester only; non-contact testers are prohibited
D) The worker must also verify the tester functions properly on a known voltage source before and after testing
Answer: B
Rationale: NFPA 70E-2026 Section 120.5 requires that absence of voltage be verified on each phase conductor and
phase-to-phase and phase-to-ground. The worker only tested line terminals, not all combinations. Option A is
irrelevant; tester rating is not the issue. Option C is false; non-contact testers are allowed if they meet requirements.
Option D is a requirement but not the violation described.
13 During an arc flash risk assessment for a 208V panel, the incident energy is calculated to be 0.8 cal/cm² at the
working distance. The panel is fed from a transformer with a 5% impedance. According to NFPA 70E-2026,
which of the following is the minimum arc flash PPE category required for working on this panel with exposed
energized parts?
A) Category 0 (N/A) - no PPE required because incident energy is below 1.2 cal/cm²
B) Category 1 - because the voltage is above 50V and work is on energized parts
C) Category 0 (N/A) - but the worker must still wear non-arc-rated clothing
