Alaska issues a 'Certificate of Fitness' rather than a traditional license for journeyman electricians. The exam is based on the NEC 2020, has 80 questions with a 4-hour time limit, and requires 70% to pass. The exam fee is approximately $75 paid to PSI. Alaska's cold climate affects conductor ampacity calculations and installation practices.

1According to the NEC 2020 as adopted by Alaska, what is the definition of a 'feeder'?

A.The circuit conductors between the service point and the main disconnect

B.All circuit conductors between the service equipment and the final branch-circuit overcurrent device

C.The circuit conductors between the transformer and the service entrance

D.The circuit conductors between the final overcurrent device and the outlet

Explanation: Per NEC Article 100, a feeder is defined as all circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device. This is distinct from both service conductors and branch circuits.

2Under Alaska's adoption of the NEC 2020, what is the minimum burial depth for PVC conduit under a public road or highway?

A.18 inches

B.24 inches

C.30 inches

D.36 inches

Explanation: Per NEC Table 300.5, PVC conduit installed under a public road or highway requires a minimum burial depth of 24 inches. This provides adequate protection from road construction activities and heavy vehicle loads.

3In Alaska, electricians receive a 'Certificate of Fitness' rather than a traditional license. Under the NEC 2020, what is the minimum size equipment grounding conductor for a 200-ampere circuit?

A.4 AWG copper

B.6 AWG copper

C.8 AWG copper

D.2 AWG copper

Explanation: Per NEC Table 250.122, the minimum equipment grounding conductor for a circuit protected by a 200-ampere overcurrent device is 6 AWG copper. Alaska issues a Certificate of Fitness for journeyman electricians through the Department of Labor and Workforce Development.

4Per the NEC 2020 as adopted by Alaska, what is the maximum distance between receptacle outlets in a hallway of a dwelling unit?

A.6 feet

B.10 feet

C.12 feet

D.No receptacle is required unless the hallway is 10 feet or longer

Explanation: Per NEC Section 210.52(H), hallways of 10 feet or more in length require at least one receptacle outlet. Hallways shorter than 10 feet do not require a receptacle. The standard wall spacing rule of 12 feet between outlets does not apply to hallways under this section.

5According to the NEC 2020 as enforced in Alaska, what is the ampacity of a 1/0 AWG copper THWN conductor at 75°C?

A.125 amperes

B.150 amperes

C.170 amperes

D.195 amperes

Explanation: Per NEC Table 310.16, a 1/0 AWG copper conductor at the 75°C column has an ampacity of 150 amperes. This is a frequently referenced value for sizing feeders and subfeeders in residential and light commercial applications.

6Per the NEC 2020 adopted in Alaska, what is the minimum size grounding electrode conductor for a service with 3/0 AWG copper service-entrance conductors?

A.8 AWG copper

B.6 AWG copper

C.4 AWG copper

D.2 AWG copper

Explanation: Per NEC Table 250.66, for service-entrance conductors sized at 3/0 AWG copper, the minimum grounding electrode conductor is 4 AWG copper. This table correlates service-entrance conductor size to the required GEC size.

7In Alaska, given the extreme cold temperatures, which NEC article addresses the installation of electrical equipment in locations where the ambient temperature may affect conductor ampacity?

A.Article 110

B.Article 310

C.Article 300

D.Article 240

Explanation: NEC Article 310 and Table 310.15(B)(1) address conductor ampacity corrections for ambient temperature. In Alaska's cold climate, conductors may actually have increased ampacity when ambient temperatures are below 30°C (86°F), as the correction factors exceed 1.00.

8Per the NEC 2020 adopted by Alaska, what is the maximum continuous load on a 30-ampere circuit breaker?

A.20 amperes

B.24 amperes

C.25 amperes

D.30 amperes

Explanation: Per NEC Section 210.20(A), continuous loads must not exceed 80% of the branch circuit overcurrent device rating. For a 30-ampere breaker: 30 × 0.80 = 24 amperes maximum continuous load.

9Under Alaska's NEC 2020 adoption, what is the standard demand factor for the first 10 kVA of general lighting in a commercial building?

A.50%

B.75%

C.100%

D.125%

Explanation: Per NEC Table 220.42, the first 10 kVA of general lighting load is calculated at 100% demand. Only the portion exceeding 10 kVA may be reduced to 50%. This ensures adequate capacity for the initial lighting load.

10Per NEC 2020 as adopted in Alaska, what is the minimum number of 20-ampere small-appliance branch circuits required in a dwelling unit?

A.One

B.Two

C.Three

D.Four

Explanation: NEC Section 210.11(C)(1) requires a minimum of two 20-ampere small-appliance branch circuits to serve receptacle outlets in the kitchen, pantry, breakfast room, dining room, and similar areas. These circuits are dedicated to small-appliance loads.

Frequently Asked Questions

What NEC edition does Alaska use for the electrician exam?

Alaska currently uses the NEC 2020 edition for the journeyman electrician Certificate of Fitness exam. Check with the Alaska Department of Labor and Workforce Development for any updates to the adopted code edition.

What is a Certificate of Fitness in Alaska?

Alaska issues a Certificate of Fitness rather than a traditional journeyman electrician license. It certifies that the holder has demonstrated competency in electrical work per the NEC and Alaska-specific requirements.

Is the Alaska electrician exam open book?

Most PSI-administered electrical exams allow a bound copy of the adopted NEC edition. No loose papers, handwritten notes, or removable tabs are permitted. Confirm current exam policies with PSI before your test date.

How does Alaska's climate affect the electrician exam?

Alaska's cold climate means conductor ampacity correction factors often result in increased ampacity (correction factors above 1.00). Questions may address cold-weather installation practices and temperature considerations.
