The Tennessee Limited Licensed Electrician (LLE) credential is issued by the Tennessee Department of Commerce and Insurance (TDCI) and permits holders to perform residential and light commercial electrical work under the supervision of a licensed master electrician. The exam is administered by PSI Exams and tests your knowledge of the National Electrical Code (NEC) as adopted and amended by Tennessee, along with practical wiring calculations and safety principles.
Our free Tennessee LLE practice test PDF gives you a printable question set you can review anywhere — at a job site, on a break, or at home. Work through the questions, check your answers against the included key, and focus your NEC study time on the areas where you need the most improvement.
The PSI Tennessee LLE exam is open book, meaning you may use a tabbed and highlighted copy of the NEC during the test. However, speed and familiarity matter — candidates who know where to find answers quickly outperform those who rely entirely on the book. Understanding the code deeply, not just locating it, is the key to passing under time pressure.
Every electrical exam begins with definitions because misunderstanding a term leads to wrong answers throughout the test. Article 100 defines critical concepts such as "ampacity," "branch circuit," "feeder," "service," "dwelling unit," "grounded conductor," "grounding electrode conductor," and dozens more. You need to distinguish between similar terms — for example, "grounded" versus "grounding," or "identified" versus "listed" — and apply them correctly in code questions.
Articles 200 through 225 govern general wiring methods and branch circuit requirements. Key topics include minimum conductor sizes for branch circuits, required receptacle spacing in dwelling units (NEC 210.52), AFCI and GFCI protection requirements, small appliance and bathroom circuits, multi-wire branch circuits, and outside branch circuit and feeder rules. Residential wiring calculation questions frequently appear, testing your ability to compute the minimum number of circuits required for a given floor plan.
Articles 230 and 215 cover electrical services and feeders respectively. Exam questions test service entrance conductor sizing, service disconnecting means requirements, clearance rules for service drops, feeder conductor sizing with demand factors, and subpanel installation rules. You should also understand the rules for service equipment location, the maximum number of service disconnects, and working clearance requirements around electrical equipment under Article 110.
Article 250 is one of the most heavily tested and most complex sections of the NEC. The exam will challenge your understanding of the difference between grounding (connecting to earth) and bonding (connecting metal parts together to equalize potential). You must know electrode conductor sizing, the grounding electrode system requirements, equipment grounding conductor sizing from Table 250.122, and bonding requirements for service equipment, gas piping, and swimming pools.
Articles 300 through 399 cover wiring methods. The LLE exam tests when you may use NM cable (Romex), when you need conduit (EMT, IMC, RMC, PVC), and the installation requirements for each. Key topics include conduit fill calculations using Chapter 9 tables, support spacing for various wiring methods, wet and damp location restrictions, and underground installation depths from Table 300.5.
Article 240 governs overcurrent protection, including breaker and fuse sizing, tap conductor rules, and the standard ampere ratings for overcurrent devices. Articles 410 and 406 cover luminaires (lighting fixtures) and receptacles — installation clearances, tamper-resistant requirements, wet location ratings, and box fill calculations. GFCI (Article 210.8) and AFCI (Article 210.12) protection requirements have expanded significantly in recent NEC editions and are guaranteed to appear on the exam.
Tennessee adopts the NEC with state-specific amendments. The TDCI publishes current amendment documents that candidates should review before the exam. Common state amendments address inspection procedures, permit requirements, and specific installation rules that differ from the base NEC. Knowing these amendments distinguishes candidates who have studied Tennessee-specific material from those who only reviewed the national code.
The LLE is the entry-level electrical license in Tennessee. LLE holders may perform electrical work only under the direct supervision of a licensed master electrician and are limited in the scope of work they can independently perform. The Journeyman Electrician license requires additional experience hours and a more comprehensive exam, allowing broader unsupervised work. The Master Electrician license is the highest tier, permitting holders to pull permits and supervise other electricians. Understanding these distinctions may appear in exam questions about scope of work and supervision requirements.
