How to Get Licensed
Step 1: Enroll in a registered apprenticeship program
Find an approved electrical apprenticeship program through the Tennessee Department of Labor & Workforce Development or through a union local (IBEW) or independent training provider. Programs combine 4000 hours of on-the-job training with 576 classroom hours minimum over 4-5 years. Submit application with high school diploma/GED and pass any entrance exams required by the program.
Step 2: Complete apprenticeship requirements
Work under a licensed master or journeyman electrician for the required hours. Log all work hours meticulously—you'll need documented proof. Complete all classroom instruction in electrical theory, code, safety, and practical skills. Maintain records with your employer and training provider. This phase typically takes 4-5 years full-time.
Step 3: Apply for journeyman license exam
After completing 4000 documented hours and classroom requirements, contact the Tennessee Board of Licensing for Electricians. Submit application with proof of hours, apprenticeship completion certificate, and exam fee (approximately $100-150). PSI administers the exam. You'll have 90 days from approval to sit for the exam.
Step 4: Pass the journeyman exam
The Tennessee journeyman electrician exam covers the National Electrical Code, local codes, electrical theory, safety practices, and practical application. Exam is typically 100-120 questions, 4-hour time limit. Passing score is usually 70%. Schedule exam through PSI online or by phone. Results typically available within 5-10 business days.
Step 5: Receive journeyman license and work toward master
Upon passing, apply for your journeyman license through the Tennessee Board of Licensing for Electricians. License fee is approximately $250 for initial issuance. You can now work independently or supervise apprentices. To become a master electrician, accumulate an additional 4000 hours as a licensed journeyman (4-5 years), then repeat the exam and application process for master license.
Step 6: Maintain annual license renewal
Both journeyman and master licenses require annual renewal by July 31st. Renewal fee is approximately $250 per year. You must complete 4 continuing education hours per year in electrical code updates, safety, or related topics. Submit renewal application and proof of CE completion to the Tennessee Board of Licensing for Electricians. Failure to renew results in license suspension and inability to pull permits.

Frequently Asked Questions
What's the difference between a master electrician and a journeyman in Tennessee?
A journeyman electrician in Tennessee has 4000 documented hours of supervised work experience and can perform electrical work under a master electrician's supervision or with a master's license on file. A master electrician has 8000 hours of experience and can operate independently, pull permits, and supervise journeymen and apprentices. Both must pass state exams and renew annually. Masters earn approximately 15-20% more per hour on average (BLS data shows median electrician wage at $30.55/hr, with masters commanding $35-40/hr in Knoxville).
How long does it take to get licensed as an electrician in Tennessee?
Becoming a journeyman electrician typically takes 4-5 years through a registered apprenticeship program (combining 4000 hours of on-the-job training with classroom instruction). You can then test for your journeyman license. To become a master electrician requires an additional 4000 hours (4-5 years) as a licensed journeyman, then passing the master exam. Fast-tracking is possible if you have equivalent experience in another state—contact the Tennessee Board of Licensing for Electricians for reciprocity evaluation.
Do I need a permit for every electrical job in Knoxville?
In Knoxville, permits are required for new circuits, panel upgrades, permanent fixture installations, and any work over 20 amps in residential settings. Minor repairs and replacements of existing outlets at the same amperage may not require permits, but it's safer to check with the City of Knoxville Building & Code Enforcement Department first. Commercial work requires permits for nearly all electrical installations. Skipping permits can result in fines, failed home inspections, and voided insurance claims.
What's the current median wage for electricians in Tennessee?
The U.S. Bureau of Labor Statistics reports the median hourly wage for electricians in Tennessee at $30.55/hr, or approximately $63,544 annually. Knoxville wages typically track slightly above state average due to local demand and cost of living. Master electricians and those in commercial/industrial sectors earn 20-35% more. Experience, specialization in high-demand areas (solar, EV charging, industrial automation), and business ownership significantly impact earnings.
What insurance do I need to work as an electrician in Knoxville?
While Tennessee does not mandate specific insurance minimums by law, most commercial clients and permit offices expect contractors to carry general liability insurance of at least $1,000,000. Workers' compensation insurance is required if you have employees. Residential contractors should carry minimum $300,000 general liability. Errors & omissions (E&O) insurance of $500,000-$1,000,000 protects against costly mistakes and is standard in Knoxville's competitive market. Check specific client contracts—they often stipulate their own insurance requirements.
