1According to the NEC, what is the definition of a 'branch circuit'?

A.The circuit conductors between the service point and the main disconnecting means

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

C.Any circuit that supplies power to a motor

D.The conductors between the transformer and the first overcurrent device

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 the NEC organizes and regulates different parts of an electrical system.

2According to the current Tennessee Limited Licensed Electrician (LLE) candidate bulletin, which NEC edition is an authorized exam reference?

A.NEC 2014

B.NEC 2017

C.NEC 2020

D.NEC 2023

Explanation: The current Prov Tennessee contractor candidate bulletin lists the 2017 NEC Handbook as an authorized reference for the LLE exam. This is an exam-reference fact; it should not be confused with a claim about the code edition adopted for every Tennessee jurisdiction.

3Under the 2017 NEC 210.8(A)(6), which dwelling-unit receptacles require GFCI protection?

A.All 125-volt receptacles in living rooms

B.All 125-volt receptacles in bedrooms

C.125-volt, single-phase, 15- and 20-ampere receptacles serving kitchen countertop surfaces

D.All 125-volt receptacles in closets

Explanation: Under the 2017 NEC 210.8(A)(6), GFCI protection is required for 125-volt, single-phase, 15- and 20-ampere receptacles serving dwelling-unit kitchen countertop surfaces. The broader voltage and location scopes in later NEC editions do not apply to this 2017-reference exam.

4What is the minimum size equipment grounding conductor required for a 60-ampere circuit per NEC Table 250.122?

A.14 AWG copper

B.12 AWG copper

C.10 AWG copper

D.8 AWG copper

Explanation: Per NEC Table 250.122, a 60-ampere overcurrent device requires a minimum 10 AWG copper equipment grounding conductor. This table is based on the rating of the overcurrent device protecting the circuit, not the conductor ampacity.

5According to NEC 250.66, what is the minimum size grounding electrode conductor for a 2/0 AWG copper service conductor?

A.8 AWG copper

B.6 AWG copper

C.4 AWG copper

D.2 AWG copper

Explanation: Per NEC Table 250.66, for service conductors sized 2/0 AWG copper (or 4/0 AWG aluminum), the minimum grounding electrode conductor is 4 AWG copper or 2 AWG aluminum. This table correlates the size of the largest service-entrance conductor with the required grounding electrode conductor.

6What is the standard voltage drop recommendation for branch circuits per NEC 210.19(A) Informational Note No. 4?

A.2%

B.3%

C.5%

D.8%

Explanation: NEC 210.19(A) Informational Note No. 4 recommends that voltage drop on branch circuits should not exceed 3%, and the total voltage drop for feeders and branch circuits combined should not exceed 5%. While these are recommendations rather than requirements, they represent good practice.

7Per 2017 NEC Table 310.15(B)(16), what is the ampacity of a 6 AWG THWN-2 copper conductor using the 75°C column?

A.40 amperes

B.55 amperes

C.65 amperes

D.75 amperes

Explanation: Per 2017 NEC Table 310.15(B)(16), 6 AWG copper has an ampacity of 65 amperes in the 75°C column. Although THWN-2 insulation is rated 90°C, the allowable ampacity at a termination cannot exceed the applicable terminal temperature limitation.

8According to NEC 314.16(B), what is the volume allowance for each 12 AWG conductor in a box fill calculation?

A.2.00 cubic inches

B.2.25 cubic inches

C.2.50 cubic inches

D.3.00 cubic inches

Explanation: Per NEC Table 314.16(B), each 12 AWG conductor requires a volume allowance of 2.25 cubic inches in a box fill calculation. This includes equipment grounding conductors counted as one conductor, device yokes counted as two conductors, and clamps counted as one conductor.

9Under 2017 NEC Table 430.52, what initial maximum percentage applies to a dual-element time-delay fuse for motor branch-circuit short-circuit and ground-fault protection?

A.125% of motor FLC

B.150% of motor FLC

C.175% of motor FLC

D.250% of motor FLC

Explanation: Under 2017 NEC Table 430.52, the initial maximum rating for a dual-element time-delay fuse is 175% of motor full-load current. Section 430.52(C)(1) contains rules for a standard size and a further increase when the motor cannot start, so 175% should not be described as an exception-free absolute maximum.

10What is the minimum height above grade for service drop conductors over a residential driveway?

A.10 feet

B.12 feet

C.15 feet

D.18 feet

Explanation: Under 2017 NEC 230.24(B)(2), service-drop conductors must have 12 feet of vertical clearance over residential property and driveways, and over commercial areas not subject to truck traffic, where the voltage limitations in that provision are met.

About the TN Electrician Exam

The Tennessee Limited Licensed Electrician (LLE) exam is administered by Prov for the Tennessee Board for Licensing Contractors. The open-book exam uses the references listed in the current Prov bulletin and covers ten domains spanning general knowledge, installation, services and circuits, overcurrent protection, grounding, conductors, raceways, hazardous locations, low-voltage systems, lighting, and general-use equipment. The LLE license applies to electrical work where the total project cost is less than $25,000; Tennessee states that it is not comparable to a journeyman or master license.
