Electrician interview questions: 23 questions and a scorecard for interviewers
The short answer
Good electrician interview questions test installation and troubleshooting skill, reading drawings, working to code and passing inspection, electrical safety including lockout/tagout, and working alongside other trades. Ask for real jobs, such as a hard fault they traced or an inspection correction they fixed, and listen for a clear method, the tests they ran and who they told. Before any interview, verify the license with the body that issued it: in the US, licensing depends on the state, such as TDLR in Texas, and for domestic work in England, check whether the candidate or their firm is registered with a competent person scheme. Score every candidate against the same five criteria so the decision rests on evidence.

When to use these questions
Electrical work done badly can injure people or start fires, so an interview needs to show how someone installs, tests and troubleshoots, and how they keep themselves and others safe, not only which jobs they have been on. The strongest evidence comes from specific installations and faults, described step by step, including what they tested and what they recorded.
For agency and contract placements, check the practical must-haves before the technical interview: a license or certification that is valid where the work is, the type of work the client needs, such as residential, commercial or industrial, the physical tasks of the role, the schedule and the start date. In general industry, OSHA requires live parts an employee may be exposed to be deenergized before work on or near them, with limited exceptions, so ask every candidate how they make a circuit safe and prove it dead before touching it.
23 electrician interview questions
Grouped by what they test. Pick the questions that match the role, ask every candidate the same ones in the same order, and score each answer against the scorecard below.
Installation and troubleshooting
Ask for real jobs. Good electricians explain their method and their checks, not only the result.
Question 1: Walk me through the last circuit or installation you completed, from layout to energizing it.
- Why ask it:
- Shows hands-on process and the checks built into it.
- A strong answer shows:
- Clear steps, such as checking the drawings and load, routing and terminating correctly, testing before energizing and labeling the work.
- Follow-up:
- What did you test before you energized it, and with which instruments?
Question 2: Tell me about a hard fault you traced, such as a nuisance trip or an intermittent dead circuit. How did you find it?
- Why ask it:
- Tests systematic troubleshooting.
- A strong answer shows:
- A logical sequence from symptoms to isolating sections and testing, rather than swapping parts until something works.
Question 3: Which test instruments do you use regularly, and how do you make sure a tester is working before you rely on it?
- Why ask it:
- Checks competence with tools and a safe testing habit.
- A strong answer shows:
- Named instruments, such as multimeters, voltage testers and insulation resistance testers, and checking the tester on a known source before and after use.
Question 4: Which kinds of work have you done most in the last two years, such as residential, commercial, industrial or service calls? Give me examples.
- Why ask it:
- Matches recent experience to the client’s work.
- A strong answer shows:
- Recent, specific projects, such as service upgrades, conduit runs, motor controls or fire alarm work, that match the role.
Question 5: Tell me about a time you found existing wiring that was unsafe or not to code. What did you do?
- Why ask it:
- Tests integrity when the job uncovers someone else’s problem.
- A strong answer shows:
- Making it safe, telling the supervisor or customer, documenting it, and not covering it up or working around it.
Drawings, codes and inspections
Electrical work has to pass inspection. Look for comfort with drawings and with the code where the candidate works.
Question 6: How do you use electrical drawings and specifications to plan your work? Walk me through a recent example.
- Why ask it:
- Tests the ability to work from plans.
- A strong answer shows:
- Reading the legend, panel schedules, one-line diagrams and specifications, and flagging conflicts before starting.
Question 7: Tell me about a time the drawings didn’t match conditions on site. What did you do?
- Why ask it:
- Tests problem-solving and communication.
- A strong answer shows:
- Stopping to verify, raising it with the foreman or through the project’s request process, and recording the change instead of improvising.
- Follow-up:
- Who did you tell, and how was the change recorded?
Question 8: Which electrical code do you work to, such as the National Electrical Code (NFPA 70) or, in the UK, BS 7671, and how do you check a code question you are unsure about?
- Why ask it:
- Shows whether they know the rules that apply where they work and check rather than guess.
- A strong answer shows:
- The code and edition used where they work, and a habit of checking the code book, the foreman or the inspector when unsure.
Question 9: Tell me about an inspection that raised corrections on your work. What happened, and what did you change?
- Why ask it:
- Tests ownership and learning.
- A strong answer shows:
- Owning the issue, fixing it promptly and changing a habit, without blaming the inspector.
Question 10: How do you prepare for a rough-in or final inspection?
- Why ask it:
- Shows organization and quality habits.
- A strong answer shows:
- Self-checking against the drawings and code, labeling, making sure the work is accessible and having any paperwork ready.
Electrical safety and lockout/tagout
Ask for exact routines. In general industry, OSHA’s lockout/tagout standard is 29 CFR 1910.147; construction electrical work falls under 29 CFR 1926 Subpart K.
Question 11: Walk me through how you make a circuit safe before you work on it.
- Why ask it:
- Tests the core safety routine every electrician needs.
- A strong answer shows:
- Identifying the source, switching off and isolating, applying their own lock and tag, and testing for absence of voltage with a proven tester before touching anything.
- Follow-up:
- What would you do if you couldn’t lock out the source?
Question 12: Have you been asked to work on something live to save time? What did you do?
- Why ask it:
- In general industry, OSHA requires live parts to be deenergized before work on or near them, with limited exceptions, such as when the employer can show that deenergizing creates additional hazards or is infeasible.
- A strong answer shows:
- Pushing back and escalating, and only working energized when it is justified, authorized and done with the right procedures and protective equipment.
Question 13: What electrical safety training have you had, such as NFPA 70E or arc flash training, and how do you choose protective equipment for a task?
- Why ask it:
- NFPA 70E is the Standard for Electrical Safety in the Workplace, so recent training on it is a useful sign of safety awareness.
- A strong answer shows:
- Recent training and a clear method for choosing protective equipment based on the task and the employer’s hazard assessment.
Question 14: How do you lock out when several trades are working on the same equipment, or when the job carries over to the next shift?
- Why ask it:
- In general industry, OSHA’s lockout/tagout standard requires group procedures that protect each worker as well as a personal lock would, and specific procedures at shift changes.
- A strong answer shows:
- Each worker’s own lock on a group device or lockbox, and a handover that keeps protection in place throughout.
Question 15: Tell me about a near miss or electric shock you were involved in or saw. What happened afterwards?
- Why ask it:
- Tests honesty and a reporting culture.
- A strong answer shows:
- Prompt reporting, no blame-shifting and a specific change in how the work was done afterwards.
Working with other trades and customers
Electricians rarely work alone. Look for early coordination, clear communication and respect for other people on site.
Question 16: Tell me about a clash with another trade, such as ductwork or plumbing in your conduit route. How was it resolved?
- Why ask it:
- Tests coordination on shared jobsites.
- A strong answer shows:
- Talking to the other trade and the foreman early, agreeing a solution and recording any change.
Question 17: How do you work with apprentices or helpers on your crew?
- Why ask it:
- Shows supervision and teaching, which matter most for journeyman and lead roles.
- A strong answer shows:
- Clear instructions, checking their work and keeping them within what they are trained and allowed to do.
Question 18: Tell me about a time you had to explain a problem or extra cost to a customer or general contractor.
- Why ask it:
- Tests communication and honesty.
- A strong answer shows:
- A plain explanation of the issue and the options, without pressure, and agreement before doing extra work.
Question 19: How do you leave your work area at the end of the day on an occupied site?
- Why ask it:
- Checks safety and respect for the people who use the building.
- A strong answer shows:
- Making circuits safe, covering open boxes and panels, clearing trip hazards and telling the right person what is live or isolated.
Must-haves and logistics
Ask these of every candidate before the technical interview, and verify the answers.
Question 20: Which electrical licenses or certifications do you hold, in which states, at what level, and when do they expire? (In the UK: are you, or the firm you work for, registered with a competent person scheme for domestic electrical work?)
- Why ask it:
- Licensing depends on where the work is: Texas requires anyone doing non-exempt electrical work to be licensed by TDLR, and California requires electricians who work for C-10 contractors to be certified.
- A strong answer shows:
- License or certification numbers, levels such as journeyman or master, and states, which you then check with the issuing body before submitting the candidate.
Question 21: The role involves [climbing ladders and working at height, lifting up to [weight], working in tight spaces such as crawl spaces and ceilings, and working outdoors in [conditions]]. Can you do these tasks, with or without adjustments?
- Why ask it:

Red flags, and questions not to ask
- Treats working live as routine, or calls lockout a waste of time.
- Cannot describe how they test for absence of voltage before touching a conductor.
- Claims a license level, state or type of work they can’t back up, or license details that don’t match the issuing body’s records.
- Blames inspectors, the drawings or other trades for every problem.
- Describes covering up or working around unsafe existing wiring instead of reporting it.
- Age, marital or family status, pregnancy or plans for children, religion, ethnicity or national origin, sexual orientation or gender identity. These are protected characteristics under the UK Equality Act 2010 and US federal law, and they say nothing about whether someone can do the job.
- Health, sickness absence or disability before an offer. You can ask whether the candidate needs any adjustments for the interview, and whether they can do the essential tasks of the job.

Electrician interview questions: frequently asked questions
Still deciding?
Bring a live vacancy and we’ll walk through where automation ends and recruiter review begins.
Ask for real examples that test installation and troubleshooting, reading drawings, working to code, electrical safety including lockout/tagout, and coordination with other trades, such as a hard fault they traced or a clash they resolved. Add must-have questions about licenses, the physical tasks of the role, the schedule and the start date, and ask every candidate the same questions in the same order.
Check with the body that issued it, in the state where the work is. In Texas, use TDLR’s license search; in California, the Department of Industrial Relations publishes lists of certified electricians and electrician trainees on data.ca.gov and offers a search using the certification number on the card. For domestic work in England, check whether the electrician or their firm is on the Electrical Competent Person Register, which GOV.UK points householders to when looking for an electrician to work on their home.
Yes, so check the rules where the work is. In Texas, anyone who performs or offers to perform non-exempt electrical work must be licensed and do that work through a licensed electrical contractor, and TDLR issues licenses including apprentice, journeyman, master and residential wireman. In California, electricians who work for C-10 licensed contractors must be certified in a category such as general electrician or residential electrician, trainees may work only under the constant supervision of a certified electrician, and certified electricians renew every three years, with 32 hours of continuing education.
Part P of the Building Regulations covers electrical safety in dwellings in England. Under Approved Document P, notifiable work, such as a new circuit, a replacement consumer unit, or changes to circuits in a special location like the space around a bath or shower, must be certified by a registered competent person, a registered third-party certifier or a building control body. Electricians registered with a competent person scheme can self-certify their work, so for domestic roles ask whether the candidate or their firm is registered; Scotland and Northern Ireland have different rules.
