How to hire an electrician: skills, licenses, tests and interview questions

Knowing how to hire an electrician comes down to three checks: the right license for the work, proof of the skills behind it, and a safe way of working. Employers who hire electricians for facilities, construction, manufacturing or field service do best with a short, repeatable process: define the license level, screen knowledge online, interview on safety and code, then run a hands-on trade test with a shortlist.

TL;DR / Key Takeaways

• Decide the setting first: residential, commercial, industrial or low-voltage.
• Levels run from apprentice to journeyman to master, plus a contractor license. Rules vary by state, so verify each one.
• Follow 7 steps: define the role, write the post, source, screen and test online, interview, run a trade test, then verify and offer.
• Check electrical theory, code, drawings, troubleshooting and safety, plus communication and teamwork.
• The US Bureau of Labor Statistics reports a median of $30.38 an hour, or $63,190 a year (May 2025).
• The guide includes 15 interview questions and a job description template you can copy.

What does an electrician do for your business?

An electrician installs, maintains, tests and repairs the electrical systems a business runs on: power distribution, lighting, controls, motors, fire alarm and data wiring, and the safety devices that protect them. Electricians read drawings, work to the electrical code your state has adopted, find and fix faults, and keep records of tests and inspections.

The job changes a lot by setting, so decide which one you are hiring for before you write a word of the job post:

• Residential and service electricians work in homes and small sites, often alone, and talk to customers every day.
• Commercial electricians wire offices, stores, hospitals and schools, usually as part of a crew on a project schedule.
• Industrial and maintenance electricians keep plants, warehouses and data centers running: motor controls, PLC-driven equipment, preventive maintenance and fast fault-finding to cut downtime.
• Low-voltage and specialty electricians handle fire alarm, security, data, solar or EV charging work, which some states license separately.

A maintenance electrician in a factory and a service electrician who visits homes need different skills and a different interview, even though both carry the same license.

What are the electrician license levels?

Electrician license levels in the US usually run from apprentice to journeyman to master, with a separate contractor license for the business. Names, hours and exams vary by state, and some cities license electricians too, so confirm the rules with the state or local licensing board for every location you hire in.

According to the Bureau of Labor Statistics Occupational Outlook Handbook, most electricians learn the trade in a 4 or 5 year apprenticeship, and most states require a licensing exam based on the National Electrical Code, with continuing education to keep the license. Indeed's hiring guide adds that some states do not license low-voltage work at all, while others license at city level.

Two points most hiring guides miss:

• A license is not the same as being qualified for live work: Under NFPA 70E, the employer decides who counts as a "qualified person" for energized work, based on safety training and shown skill on the specific equipment. A journeyman card alone does not make someone qualified on your switchgear, so plan for site-specific training after the hire.
• Code editions differ by state: The 2026 National Electrical Code is out, but each state adopts new editions on its own timetable, so some sites still work to the 2020 or 2023 edition. Washington, for example, has started rulemaking to adopt the 2026 NEC. Ask candidates which edition they work to and check it matches your sites.

How to hire an electrician: full-time employee or contractor?

How to hire an electrician depends first on how much electrical work you have. A full-time electrician fits when you have steady work every week: a plant, a hospital campus, a property portfolio or a service business. A licensed electrical contractor fits one-off projects, peaks in demand, or work that needs a master's permit you do not hold in-house.

• Hire full-time when downtime is costly, when people need to know your equipment well, or when you would otherwise pay contractor call-out rates several times a week.
• Use a contractor for new builds, upgrades that need permits and design sign-off, or specialist work such as high-voltage testing.
• Mix both when a small in-house team handles maintenance and a contractor takes the large projects.

Pro tip: If you hire full-time, decide the license level by the riskiest task the person will do alone, not by the average day. A maintenance role that includes 480V motor control work needs a journeyman at minimum.

How to hire an electrician in 7 steps?

Hiring an electrician works best as a seven-step funnel: define the role, write a clear job post, source widely, screen and test knowledge online, run a structured interview, hold a hands-on trade test for the shortlist, then verify and make the offer. Testing knowledge early means your senior electricians only give site time to candidates who already know the code.

1. Define the role: Setting (residential, commercial, industrial, maintenance), license level, shift pattern, on-call duty, travel and whether a driver's license is needed.
2. Write the job post: Lead with the work, the license required and the pay range. Many states now require pay ranges in job ads, and electricians compare offers on pay, overtime and tools provided.
3. Source widely: Apprenticeship programs, union halls, trade schools, referrals from your current electricians, and job boards. Details are in the sourcing section below.
4. Screen and test: Check the license number against the state board and send a short online test on electrical theory, code, troubleshooting and safety.
5. Interview: Use the same structured questions for every candidate: safety, code, troubleshooting scenarios and teamwork.
6. Trade test on site: Give the top 3 to 5 candidates a real task, such as wiring a control circuit or finding a planted fault, and score it with a rubric.
7. Verify and offer: Call references from supervisors, confirm insurance where relevant, run any driving record or background check your policy requires, then make the offer fast. Good electricians rarely stay on the market for long.

In my work with hiring teams that hire trades, the slowest part of the process is almost always the gap between the first call and the trade test, because a supervisor has to free up a morning. Moving the knowledge check online is the easiest way to close that gap.

What skills should you look for in an electrician?

Electrician skills fall into two groups: technical skills that keep the work safe and to code, and working skills that decide how well the person fits a crew or faces a customer. The BLS lists color vision, critical thinking, customer service, physical stamina and troubleshooting as the key qualities for the job.

Technical skills to check

• Electrical theory: Ohm's law, load calculations, single-phase and three-phase systems, voltage drop.
• Code knowledge: working to the NEC edition and local amendments your sites use, including grounding, bonding and conductor sizing.
• Reading drawings: blueprints, one-line diagrams, schematics and control ladder diagrams.
• Installation: conduit bending, cable pulling, terminations, panel and device installation.
• Troubleshooting: a logical, step-by-step method to isolate faults with a multimeter, clamp meter and insulation tester.
• Safety practice: lockout/tagout, testing for absence of voltage, arc flash boundaries and the right PPE.
• Setting-specific skills: motor controls, VFDs and PLCs for industrial roles; fire alarm or data cabling for low-voltage roles; EV chargers and solar for newer service work.

Working skills to check

• Communication: explaining a fault and a fix in plain words to a supervisor, a customer or another trade.
• Attention to detail: labeling, torque values, test records and clean terminations.
• Planning: ordering materials, sequencing work and finishing on schedule.
• Teamwork: working beside plumbers, HVAC techs and general contractors on a shared site.
• Willingness to learn: keeping up with code changes, new equipment and continuing education.

How do you test an electrician's skills before hiring?

Testing an electrician's skills works best in two layers: a short online test to screen knowledge for every applicant, then a hands-on trade test for the shortlist. The online layer is cheap and fast; the hands-on layer is expensive but shows how the person actually works with tools and live risk.

Testlify has ready-made tests you can send in the first layer:

• The Electrician Technical Knowledge test covers electrical theory and systems, troubleshooting and electrical safety in about 10 minutes.
• The Electrician (Intermediate) test checks wiring, troubleshooting, electrical code, equipment handling and blueprint reading.
• The Electrical Aptitude test suits apprentice and trainee hiring, where you are testing ability to learn rather than experience.
• The Maintenance Technician (Electrical) test fits plant and facilities roles.

You can add your own questions next to a ready-made test, for example a photo of a panel with a code violation to spot, a short video answer explaining a lockout/tagout sequence, or a file upload of a past test record. For more ideas, see how to hire top talent using an electrician test.

Score the second layer, the trade test, with a simple weighted scorecard so every assessor judges the same things:

Any candidate who skips a safety step fails the trade test, whatever the other scores say. We have seen teams adopt that single rule and find it settles most debates between assessors.

Where can you find qualified electricians?

Qualified electricians are easiest to find through the channels the trade already uses: apprenticeship programs, unions, trade schools and referrals, backed by job boards for reach. Demand is high, so treat sourcing as ongoing rather than a one-off post.

• Registered apprenticeship programs: Joint union and contractor programs and open-shop programs produce new journeymen every year, and you can sponsor apprentices yourself.
• Union halls: The IBEW local in your area can dispatch journeymen for union work.
• Trade schools and community colleges: career offices can share graduates of electrical programs.
• Referrals: Your current electricians know who is good. A referral bonus is often the cheapest hire you will make.
• Military transition programs: Veterans with electrical training in the forces often hold transferable skills and a strong safety habit.
• Job boards and social media: General job boards, trade groups and local Facebook groups reach active job seekers.
• Suppliers and contractors: Electrical supply house staff and general contractors meet many electricians each week.

How much does it cost to hire an electrician?

The cost to hire an electrician as an employee starts with pay: the BLS reports a median wage of $30.38 an hour, or $63,190 a year, for electricians in May 2025. Pay rises with license level, overtime, on-call duty, union rates and local demand, so check local wage data before you set a range.

Market pressure matters too. BLS projects electrician jobs to grow 9% from 2025 to 2035, with about 72,700 openings a year on average, many from people retiring. Associated Builders and Contractors figures reported by Distribution Strategy say construction must bring in 349,000 new workers in 2026, and about one-fifth of US electricians are older than 55. Data center building adds more demand.

Beyond pay, budget for:

• Tools, vans and PPE, including arc-rated clothing and test equipment.
• Training, such as NFPA 70E safety training and equipment-specific training.
• Licensing and continuing education fees, which many employers cover.
• The cost of a slow process: every week a role stays open means overtime for the rest of the crew or contractor call-out fees.

If you hire a contractor instead, you pay an hourly or fixed project rate that covers the contractor's overhead and insurance, so it will sit above the employee wage.

What interview questions should you ask an electrician?

Electrician interview questions should test safety habits, code knowledge, troubleshooting method and how the person works with others. Ask every candidate the same questions in the same order and score the answers against what a good answer shows.

Safety

1. Walk me through how you lock out and verify a circuit before you work on it. A good answer names each step, including testing the tester.
2. Tell me about a time you stopped a job because something was unsafe. Look for a real example and a calm, firm decision.
3. How do you decide what PPE you need for a task? Listen for arc flash labels, incident energy and approach boundaries.

Code and technical knowledge

1. Which edition of the NEC have you worked to, and what changed that affected your work? Shows how current the candidate is.
2. How do you size a conductor for a new 40-amp circuit with a long run? Look for ampacity, temperature rating and voltage drop.
3. What is the difference between grounding and bonding, and why do both matter? Checks core understanding.
4. How do you read a one-line diagram for a building you have never seen? Shows a method for drawings.

Troubleshooting

1. A breaker trips every afternoon but never in the morning. How do you find the cause? Look for load patterns, testing and ruling out causes in order.
2. A three-phase motor runs hot and loud. What do you check first? Shows industrial knowledge for maintenance roles.
3. Describe the hardest fault you have found and how you found it. Strong candidates explain their reasoning, not only the fix.

Teamwork and customers

1. How do you handle a disagreement with another trade over who works where on a site? Look for respect and a practical fix.
2. How do you explain a costly repair to a customer or a manager who is not technical? Plain words and options are a good sign.
3. How do you train or supervise an apprentice? Important for journeymen and masters.

Wrap-up

1. How do you keep up with code changes and new equipment such as EV chargers or solar? Shows willingness to learn.
2. What kind of work do you want more of in your next role? Helps you match the candidate to the right crew.

You can run these questions as a one-way video interview before the site visit, so supervisors watch answers when they have time instead of booking calls.
