1According to the NEC as adopted by Alabama, what is the definition of a 'branch circuit'?

A.The circuit conductors between the final overcurrent device and the outlet(s)

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

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

D.The circuit conductors between two panelboards

Explanation: Per NEC Article 100, a branch circuit is defined as the circuit conductors between the final overcurrent device protecting the circuit and the outlet(s). This definition is fundamental to understanding how electrical systems are divided and protected.

2Under Alabama's adoption of the NEC 2023, what is the minimum size copper grounding electrode conductor required for a 200-ampere service?

A.4 AWG copper

B.6 AWG copper

C.2 AWG copper

D.1/0 AWG copper

Explanation: Per NEC Table 250.66, a 200-ampere service with copper service-entrance conductors sized at 2/0 AWG or 3/0 AWG requires a minimum 4 AWG copper grounding electrode conductor. This table correlates the size of the largest service-entrance conductor to the grounding electrode conductor size.

3Per the NEC 2023 as enforced by the Alabama Electrical Contractors Board, what is the maximum voltage allowed for a Class 2 circuit?

A.30 volts

B.42.4 volts peak

C.150 volts

D.100 volts

Explanation: Per NEC Article 725 and Chapter 9 Table 11(A), Class 2 circuits are limited to 150 volts maximum, with current limitations based on the voltage level. Class 2 power sources must be listed and comply with the power limitations specified in the tables.

4In Alabama, what is the minimum number of 20-ampere small-appliance branch circuits required for the kitchen and dining areas of 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 all wall and floor receptacle outlets in the kitchen, pantry, breakfast room, dining room, and similar areas. These circuits must serve only receptacle outlets in these areas.

5According to the NEC 2023 as adopted in Alabama, what is the ampacity of a 6 AWG copper THWN-2 conductor at 75°C column?

A.55 amperes

B.65 amperes

C.75 amperes

D.85 amperes

Explanation: Per NEC Table 310.16, a 6 AWG copper conductor with THWN-2 insulation rated at 75°C has an ampacity of 65 amperes. While THWN-2 is rated for 90°C, Section 310.15(B)(2) generally requires using the 75°C column for termination purposes unless equipment is rated and listed for higher temperatures.

6Under Alabama's NEC adoption, what is the maximum percentage of conduit fill allowed for three or more conductors in a raceway?

A.31%

B.40%

C.53%

D.60%

Explanation: Per NEC Chapter 9, Table 1, when three or more conductors are installed in a raceway, the maximum fill is 40% of the conduit's total cross-sectional area. This allows adequate space for heat dissipation and ease of pulling conductors.

7Per NEC 2023 in Alabama, what is the minimum burial depth for rigid metal conduit (RMC) containing circuit conductors under a residential driveway?

A.6 inches

B.12 inches

C.18 inches

D.24 inches

Explanation: Per NEC Table 300.5, rigid metal conduit (RMC) under a residential driveway requires a minimum burial depth of 6 inches. RMC provides significant mechanical protection, which is why the NEC allows the shallowest burial depth for this raceway type.

8In Alabama, according to NEC Article 430, what is the maximum rating of a branch-circuit short-circuit and ground-fault protective device for a motor with a full-load current of 40 amperes using an inverse-time circuit breaker?

A.80 amperes

B.100 amperes

C.125 amperes

D.150 amperes

Explanation: Per NEC Table 430.52, an inverse-time circuit breaker used for motor branch-circuit short-circuit and ground-fault protection is permitted at a maximum of 250% of the motor full-load current. For a 40-ampere motor: 40 × 2.50 = 100 amperes. This provides adequate protection while allowing motor starting current.

9Under the NEC 2023 adopted by the AECB, what is the general lighting load in volt-amperes per square foot for a dwelling unit?

A.2 VA per square foot

B.3 VA per square foot

C.3.5 VA per square foot

D.5 VA per square foot

Explanation: Per NEC Table 220.12, the general lighting load for dwelling units is calculated at 3 volt-amperes per square foot of habitable space. This value is used for load calculations to determine the minimum number of branch circuits and service sizing.

10Per NEC 2023 as adopted in Alabama, what is the minimum height above finished grade for service drop conductors over a residential driveway?

A.10 feet

B.12 feet

C.15 feet

D.18 feet

Explanation: NEC Section 230.24(B)(1) requires service drop conductors to maintain a minimum clearance of 12 feet above finished grade over residential driveways and commercial areas not subject to truck traffic. This clearance ensures vehicles can pass safely underneath.
