Free practice test — 12 questions with full explanations
Original CraftPATH practice questions. These are not real exam questions. Every answer includes the reasoning, why each wrong option fails, the code area it comes from, and the misconception it targets.
Question 1. To perform electrical work for compensation as a business in Arizona, the state requires:
Arizona Statutes and Rules · Medium · Objective: Understand Arizona's licensing structure.
- A. A statewide journeyman electrician license
- B. An ROC contractor license in the appropriate classification, with a listed qualifying party (correct)
- C. A master electrician certificate from each county
- D. No license, only a city business permit
Correct answer: B. An ROC contractor license in the appropriate classification, with a listed qualifying party
Why this is right: Arizona regulates contracting rather than individual electricians. The Registrar of Contractors issues the license to the entity, and a qualifying party who passed the examinations must be listed with it.
Why the other options are wrong:
- A. A statewide journeyman electrician license — Arizona does not issue statewide journeyman electrician licenses.
- C. A master electrician certificate from each county — Counties do not issue master electrician certificates in place of ROC licensure.
- D. No license, only a city business permit — Contracting without a license is a violation under Title 32.
Where this shows up on the job: Workers moving from a journeyman-license state are often surprised there is no individual card to transfer.
Code reference: A.R.S. Title 32, Chapter 10
Common misconception: Looking for an Arizona journeyman license that does not exist.
Question 2. If the qualifying party leaves a licensed Arizona contracting business, the business must:
Arizona Statutes and Rules · Medium · Objective: Understand the qualifying party requirement.
- A. Continue operating indefinitely under the existing license
- B. Replace the qualifying party within the period allowed by the ROC or the license is suspended (correct)
- C. Reapply as a brand-new company
- D. Transfer the license to the departing individual
Correct answer: B. Replace the qualifying party within the period allowed by the ROC or the license is suspended
Why this is right: The license depends on a listed qualifying party. The ROC allows a limited window to name and qualify a replacement, after which the license is suspended and the company cannot lawfully contract.
Why the other options are wrong:
- A. Continue operating indefinitely under the existing license — The license does not survive indefinitely without a qualifying party.
- C. Reapply as a brand-new company — A replacement qualifying party is normally sufficient without starting over.
- D. Transfer the license to the departing individual — The license belongs to the entity, not the individual.
Where this shows up on the job: Growing shops keep a second qualified person examined in advance so a resignation never suspends the license.
Code reference: A.R.S. Title 32, Chapter 10; A.A.C. Title 4 Chapter 9
Common misconception: Believing the qualifying party is a formality after the license is issued.
Question 3. Which National Electrical Code edition governs an electrical installation in Arizona?
General Requirements and Code Navigation · Medium · Objective: Identify which code edition applies.
- A. The newest NEC published, everywhere in the state
- B. The edition adopted by the city or county where the work is performed (correct)
- C. The 2008 NEC statewide, permanently
- D. Whichever edition the contractor prefers
Correct answer: B. The edition adopted by the city or county where the work is performed
Why this is right: Arizona has no statewide electrical code adoption, so each municipality or county adopts its own NEC edition with local amendments, and the adopting jurisdiction's edition is what inspectors enforce.
Why the other options are wrong:
- A. The newest NEC published, everywhere in the state — Local jurisdictions frequently lag the newest published edition.
- C. The 2008 NEC statewide, permanently — There is no permanent statewide edition.
- D. Whichever edition the contractor prefers — Code edition is not the contractor's choice.
Where this shows up on the job: A company working Phoenix, Mesa and unincorporated Maricopa County can face three different adopted editions in one week.
Code reference: Arizona local jurisdiction code adoptions; NFPA 70
Common misconception: Assuming a single statewide electrical code exists in Arizona.
Question 4. Conductors run in a rooftop raceway in Phoenix where the ambient temperature far exceeds 30 degrees Celsius must have their ampacity:
Conductors, Ampacity and Overcurrent Protection · Hard · Objective: Apply ambient temperature correction.
- A. Increased, because heat improves conductivity
- B. Corrected downward using the ambient temperature correction factors (correct)
- C. Left unchanged, because the table already accounts for climate
- D. Corrected only if more than nine conductors are present
Correct answer: B. Corrected downward using the ambient temperature correction factors
Why this is right: Table ampacities assume a 30 degree Celsius ambient. Higher ambient temperatures reduce the conductor's ability to shed heat, so the correction factors reduce usable ampacity, and rooftop runs face additional temperature adder considerations.
Why the other options are wrong:
- A. Increased, because heat improves conductivity — Heat increases resistance and reduces safe ampacity.
- C. Left unchanged, because the table already accounts for climate — The base table does not account for local climate.
- D. Corrected only if more than nine conductors are present — Conductor count triggers adjustment, which is a separate factor from ambient correction.
Where this shows up on the job: Rooftop conduit in the Arizona sun is the single most common place undersized conductors get installed.
Code reference: NEC 310.15 ambient correction and 310.15(A)(2) rooftop provisions
Common misconception: Confusing conductor-count adjustment with ambient temperature correction.
Question 5. When seven current-carrying conductors share a raceway longer than 24 inches, the allowable ampacity must be adjusted to:
Conductors, Ampacity and Overcurrent Protection · Hard · Objective: Apply conduit fill adjustment.
- A. 80 percent
- B. 70 percent (correct)
- C. 60 percent
- D. 50 percent
Correct answer: B. 70 percent
Why this is right: The adjustment table applies 80 percent for four to six conductors, 70 percent for seven to nine, 50 percent for ten to twenty, and lower factors above that. Bundled conductors cannot dissipate heat independently.
Why the other options are wrong:
- A. 80 percent — 80 percent covers four through six current-carrying conductors.
- C. 60 percent — 60 percent is not a step in this table.
- D. 50 percent — 50 percent begins at ten conductors.
Where this shows up on the job: Neutrals on multiwire branch circuits with nonlinear loads count as current-carrying and push you into the next bracket.
Code reference: NEC Table 310.15(C)(1)
Common misconception: Counting equipment grounding conductors as current-carrying.
Question 6. A continuous load requires the branch circuit overcurrent device and conductors to be sized at not less than:
Branch Circuits, Feeders and Load Calculations · Hard · Objective: Apply continuous load sizing.
- A. 100 percent of the continuous load
- B. 125 percent of the continuous load plus 100 percent of the noncontinuous load (correct)
- C. 80 percent of the total load
- D. 150 percent of the continuous load
Correct answer: B. 125 percent of the continuous load plus 100 percent of the noncontinuous load
Why this is right: A continuous load runs three hours or more, so the 125 percent multiplier keeps the overcurrent device and terminations from operating at their thermal limit for extended periods.
Why the other options are wrong:
- A. 100 percent of the continuous load — 100 percent ignores the sustained heating effect.
- C. 80 percent of the total load — The 80 percent rule is the same requirement stated from the device side, not a substitute calculation.
- D. 150 percent of the continuous load — 150 percent is not the code multiplier.
Where this shows up on the job: Continuous lighting and commercial HVAC loads in Arizona strip malls are the typical exam scenario for this rule.
Code reference: NEC 210.19(A) and 210.20(A)
Common misconception: Applying 125 percent to noncontinuous loads as well.
Question 7. The general lighting load for a dwelling unit is calculated at:
Branch Circuits, Feeders and Load Calculations · Hard · Objective: Apply dwelling general lighting load.
- A. 1 volt-ampere per square foot
- B. 3 volt-amperes per square foot (correct)
- C. 5 volt-amperes per square foot
- D. 10 volt-amperes per square foot
Correct answer: B. 3 volt-amperes per square foot
Why this is right: The general lighting and general-use receptacle load for dwellings is computed at 3 volt-amperes per square foot of habitable floor area, measured from outside dimensions and excluding unfinished space not adaptable for use.
Why the other options are wrong:
- A. 1 volt-ampere per square foot — 1 volt-ampere per square foot applies to certain storage occupancies.
- C. 5 volt-amperes per square foot — 5 volt-amperes per square foot is not the dwelling value.
- D. 10 volt-amperes per square foot — 10 volt-amperes per square foot is far above the dwelling value.
Where this shows up on the job: Including an unconditioned garage in the square footage inflates the service size and fails the calculation question.
Code reference: NEC 220.41 general lighting load
Common misconception: Using gross building area instead of habitable area.
Question 8. In a detached garage subpanel fed by a four-wire feeder, the neutral conductors must be:
Grounding, Bonding and Services · Hard · Objective: Apply neutral and ground separation.
- A. Bonded to the subpanel enclosure
- B. Isolated from the enclosure and kept separate from the equipment grounding conductors (correct)
- C. Connected only to a driven ground rod
- D. Landed on the same bar as the grounds
Correct answer: B. Isolated from the enclosure and kept separate from the equipment grounding conductors
Why this is right: The neutral is bonded to ground only at the service disconnect. Bonding downstream places normal neutral current on equipment grounding conductors and metal parts, creating parallel paths and shock hazard, though the detached structure still needs its own grounding electrode.
Why the other options are wrong:
- A. Bonded to the subpanel enclosure — That is the exact violation being tested.
- C. Connected only to a driven ground rod — A ground rod does not replace the equipment grounding conductor.
- D. Landed on the same bar as the grounds — Sharing a bar bonds neutral to ground.
Where this shows up on the job: Older three-wire feeders to detached structures are no longer permitted for new work and are a common correction.
Code reference: NEC 250.24, 250.32 and 250.142
Common misconception: Treating a detached building panel like a service.
Question 9. A concrete-encased electrode, where present in a new building foundation, must be:
Grounding, Bonding and Services · Medium · Objective: Apply grounding electrode requirements.
- A. Ignored if a ground rod is installed
- B. Used as part of the grounding electrode system (correct)
- C. Installed only in commercial buildings
- D. Bonded only if the soil resistivity is high
Correct answer: B. Used as part of the grounding electrode system
Why this is right: All electrodes present at a building must be bonded together into a grounding electrode system, and a concrete-encased electrode is required to be used where it exists at a new structure because of its low, stable resistance.
Why the other options are wrong:
- A. Ignored if a ground rod is installed — A ground rod does not excuse omitting a present electrode.
- C. Installed only in commercial buildings — The requirement is not limited to commercial construction.
- D. Bonded only if the soil resistivity is high — Soil resistivity does not make the electrode optional.
Where this shows up on the job: Missing the rebar stub-up before the slab pour is an expensive, common coordination failure.
Code reference: NEC 250.50 and 250.52(A)(3)
Common misconception: Believing any single electrode satisfies the requirement.
Question 10. Branch circuit conductors for a single continuous-duty motor must have an ampacity of at least:
Motors, HVAC, Solar and Special Systems · Hard · Objective: Apply motor conductor sizing.
- A. 100 percent of the nameplate full-load amperes
- B. 125 percent of the full-load current value from the applicable NEC table (correct)
- C. 125 percent of the nameplate amperes
- D. 80 percent of the locked rotor current
Correct answer: B. 125 percent of the full-load current value from the applicable NEC table
Why this is right: Conductor sizing uses the table full-load current value, not the nameplate, multiplied by 125 percent. The nameplate value is used for overload protection sizing, which is a different calculation.
Why the other options are wrong:
- A. 100 percent of the nameplate full-load amperes — That omits the 125 percent factor and uses the wrong current basis.
- C. 125 percent of the nameplate amperes — Nameplate current belongs in the overload calculation.
- D. 80 percent of the locked rotor current — Locked rotor current is used for short-circuit and disconnect considerations.
Where this shows up on the job: Getting the table-versus-nameplate distinction wrong is the single most reliable way to miss motor questions.
Code reference: NEC 430.6(A), 430.22 and 430.32
Common misconception: Using one current value for every motor calculation.
Question 11. Rapid shutdown requirements for a rooftop PV system exist primarily to:
Motors, HVAC, Solar and Special Systems · Hard · Objective: Apply photovoltaic rapid shutdown concepts.
- A. Improve array energy production
- B. Reduce shock hazard to firefighters by limiting energized conductors outside the array boundary (correct)
- C. Prevent inverter overheating
- D. Satisfy utility interconnection metering
Correct answer: B. Reduce shock hazard to firefighters by limiting energized conductors outside the array boundary
Why this is right: Rapid shutdown limits the voltage on conductors leaving the array boundary within a set time after initiation so emergency responders can work on a roof without energized DC conductors running through the building.
Why the other options are wrong:
- A. Improve array energy production — It has no production benefit.
- C. Prevent inverter overheating — Inverter thermal protection is a separate function.
- D. Satisfy utility interconnection metering — Metering and interconnection are utility requirements, not the basis for this rule.
Where this shows up on the job: Arizona's high PV density makes this one of the most frequently inspected provisions in the state.
Code reference: NEC 690.12
Common misconception: Treating rapid shutdown as equivalent to an AC disconnect.
Question 12. The disconnecting means for an outdoor air conditioning condensing unit must be:
Motors, HVAC, Solar and Special Systems · Medium · Objective: Apply HVAC disconnect location rules.
- A. Located inside the building at the panel only
- B. Within sight from and readily accessible from the equipment (correct)
- C. Anywhere on the property if labeled
- D. Omitted when the breaker is lockable
Correct answer: B. Within sight from and readily accessible from the equipment
Why this is right: The disconnect must be within sight from and readily accessible from the air conditioning or refrigerating equipment so a technician can verify the equipment is de-energized before servicing it.
Why the other options are wrong:
- A. Located inside the building at the panel only — A panel inside the house is not within sight of the condenser.
- C. Anywhere on the property if labeled — Labeling does not substitute for the within-sight requirement here.
- D. Omitted when the breaker is lockable — A lockable breaker does not satisfy this specific requirement for this equipment.
Where this shows up on the job: Condensers placed behind walls or landscaping with no local disconnect are a routine correction on Arizona residential inspections.
Code reference: NEC 440.14
Common misconception: Assuming within sight means somewhere on the same wall regardless of visibility.
How to study for the Arizona electrical contractor exam
Confirm the adopted code edition for your jurisdiction
Arizona has no statewide electrical code adoption. Before you buy a code book, confirm which NEC edition the ROC's examination provider references and which edition the cities you work in have adopted, because article numbering and requirements move between cycles.
Treat statutes and rules as a separate exam
The statutes-and-rules exam covers classifications and scope, the qualifying party, bonding and the recovery fund, contract and advertising requirements, and the complaint process. These are memorization points with no calculation, which makes them the cheapest points on the whole licensing path.
Drill ampacity math in Arizona conditions
Ambient correction and conductor-count adjustment are applied together, not as alternatives, and rooftop raceway questions are common. Work problems until you can run correction, adjustment and the termination temperature limit in sequence without hesitating.
Own the grounding topics
Electrode systems and electrode conductor sizing, equipment grounding conductor sizing, neutral-to-ground bonding only at the service disconnect, and detached structure feeders. These recur every cycle and are the most commonly corrected items in the field.
Run a six-week plan
Week one: statutes, rules and definitions. Week two: branch circuits, feeders and load calculations. Week three: conductors, ampacity and overcurrent protection. Week four: grounding, bonding and services. Week five: motors, HVAC, solar and special systems. Week six: full-length timed sets under exam conditions.
Frequently asked questions
Does Arizona issue a journeyman electrician license?
No. Arizona regulates contracting through the Registrar of Contractors rather than licensing individual electricians statewide. Some cities have their own requirements, so check locally.
What exams do I have to pass?
Generally a statutes-and-rules examination on Arizona contracting law plus a trade examination for your classification. Confirm the current requirements for your classification with the ROC.
Who is the qualifying party?
The person listed with the license who passed the required examinations. If that person leaves, the business must name and qualify a replacement within the period the ROC allows or the license is suspended.
Which NEC edition should I study?
The edition referenced by the examination provider, which may differ from the edition your city has adopted for inspections. Verify both before buying a code book.
How much experience do I need?
The ROC sets the practical or management experience requirement by classification. We leave the figure pending here rather than estimating it.
Are these real Arizona exam questions?
No. Every question here is original CraftPATH material written to the same subject areas the exam covers. We do not reproduce live examination content.
How long should I study?
Experienced electricians typically need six to ten weeks, weighted toward load calculations, ampacity math with ambient correction, grounding, and the Arizona statutes and rules material.
