TN LLE content outline and where to practise each area

The content areas below are copied from the official TN LLE content outline published by Tennessee Board for Licensing Contractors. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through TN LLE questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: According to Tennessee licensing requirements, can a Limited Licensed Electrician install a central air conditioning system in a new commercial building?

1. Yes, without restrictions
2. Yes, if the system is under 200 amperes
3. No, this typically requires a full electrical contractor license
4. Yes, but only in buildings under 5,000 square feet

Answer: C. No, this typically requires a full electrical contractor license

Explanation:

The correct answer is that a Limited Licensed Electrician typically cannot install a central air conditioning system in a new commercial building, because that work generally calls for a full electrical contractor license. The limited license is aimed at residential and small commercial work.

"Yes, without restrictions" is wrong because the license does have limits. "Yes, if the system is under 200 amperes" and "Yes, but only in buildings under 5,000 square feet" are wrong because they invent a tidy threshold that is not how scope is defined. Scope is set by the license class and the type of work, not by one convenient cutoff.

The rule to remember: before taking on a job, check it against the scope of your license class, and when the work is large or commercial, confirm with the Board rather than assuming.

Example 2

Question: What is the minimum gauge of wire typically used for 20-amp circuits in residential wiring?

1. 10-gauge
2. 12-gauge
3. 14-gauge
4. 16-gauge

Answer: B. 12-gauge

Explanation:

The correct answer is 12-gauge. A 20-amp circuit needs a conductor thick enough to carry that current without overheating, and 12-gauge copper is the size typically used in residential wiring for that rating.

14-gauge and 16-gauge are wrong because they are thinner. A thinner wire has more resistance and heats up sooner, so it would be a fire hazard behind a 20-amp breaker. 10-gauge is thicker than needed for this circuit. It would be safe electrically, but it is not the minimum, and the question asks for the minimum.

The rule to remember: a lower gauge number means a thicker wire, and the wire must be sized to suit the breaker that protects it. Always check the current table for your installation conditions.

Example 3

Question: What is the correct procedure if an electrical tool or cord is found to be damaged on a job site?

1. Wrap it with electrical tape and continue working
2. Remove it from service immediately and tag it as defective
3. Use it only for light-duty tasks
4. Report it at the end of the work day

Answer: B. Remove it from service immediately and tag it as defective

Explanation:

The correct answer is to remove the damaged tool or cord from service immediately and tag it as defective. That stops anyone else from picking it up and getting shocked or burned.

Wrapping it with electrical tape is wrong because tape hides damage without restoring the insulation or the strain relief. Using it only for light-duty tasks is wrong because even a light task can expose a worker to live parts or a faulty ground. Reporting it at the end of the work day is wrong because the hazard stays in use for the rest of the shift.

The rule to remember: if equipment is unsafe, take it out of use right away, label it clearly, and report it. Repair or replacement is done by a qualified person afterward, not on the spot.

How to use these practice tests

Start by reading the official exam information on the Prov page so you know the format, the fee, and what you are allowed to bring. Then take a short practice set in each content area to see where you stand. Do not worry about the scores at this stage. Note which areas feel slow or unfamiliar.

Spend most of your time on those weaker areas. For each question you miss, open your code book and find the exact article and table that answers it, then write down where it was. Because the real exam is open book, being able to locate a rule quickly is worth as much as remembering it. Tab your book and practise using the index.

For calculation topics such as load calculations, box fill, and service and feeder sizing, write out every step by hand instead of jumping to the answer. Redo any question you got wrong a few days later without looking at the explanation.

Closer to test day, work through mixed sets under a timer, using the same time limit as the real exam. Keep in mind that our questions are written with AI tools and are not real exam questions, so use them to build habits and find gaps, and rely on your code book for the final answer.

• Topics: Time Management
• Questions: All Sections

You must answer at least 29 questions correctly to achieve the required 73% passing score.

• Topics: All Categories
• Questions: Minimum 29

Since the TN LLE is open book, your ability to quickly find codes in the NEC index is more valuable than memorization. Practice locating TN LLE topics like grounding, ampacity, and box fill.

Expect to spend around $200-$300 total for your exam, license, and basic study materials. This small investment can lead to a career as a Nashville electrician earning over $50k/year.

Sample TN LLE - Tennessee Limited Licensed Electrician Practice Questions

Try these questions from our free TN LLE - Tennessee Limited Licensed Electrician practice tests. The correct answer and an explanation follow each question.

1. An electrician is wiring a livestock confinement area in an agricultural building, which is subject to a corrosive atmosphere from animal waste. According to NEC Article 547, which of the following wiring methods is generally permitted?

   • A. Type NMC (nonmetallic-sheathed cable).
   • B. Standard Type NM-B (nonmetallic-sheathed cable).
   • C. Electrical Metallic Tubing (EMT).
   • D. Flexible Metal Conduit (FMC).

Answer: A. Type NMC (nonmetallic-sheathed cable).

NEC 547.5 specifies permitted wiring methods for agricultural buildings, especially in areas with dust, moisture, and corrosive atmospheres. Type NMC cable, which has a corrosion-resistant outer jacket, is listed as a suitable method. Standard Type NM-B, EMT, and FMC are generally not suitable for such corrosive environments without additional protection.

Answer: C. 10 AWG

NEC Table 250.122, 'Minimum Size Equipment Grounding Conductors for Grounding Raceway and Equipment,' dictates the size of the EGC based on the rating of the overcurrent protective device. For a circuit with a rating of 60 amps, the table requires a minimum of a 10 AWG copper equipment grounding conductor.

Answer: C. 10% of the feeder overcurrent device rating.

According to the 10-foot tap rule in NEC 240.21(B)(1), if the tap conductors leave the enclosure, their ampacity must be at least 10% of the rating of the overcurrent device protecting the feeder. In this case, 10% of 200A is 20A. The tap conductors must also have an ampacity not less than the calculated load and the rating of the device they terminate on.

Answer: C. The conductor must be wrapped in a clockwise direction around the screw.

NEC 110.14(A) requires that terminals be used according to the manufacturer's instructions. Standard practice, enforced by inspectors and integral to proper workmanship, dictates that conductors be wrapped clockwise around a screw terminal. This ensures that tightening the screw also tightens the wire loop, creating a secure connection. Wrapping counter-clockwise would cause the loop to open and loosen as the screw is tightened.
