Electricians are highly skilled professionals who repair and install wiring appliances and components for electrical systems, such as lighting, heating, ventilation and air conditioning (HVAC), security and computer network systems. While many electricians work alone, large businesses employ several of these professionals to lead helpers and apprentices. Experienced electricians usually work together with building engineers, construction specialists and architects to assist in the installation or maintenance of electric and power systems. In this article, we discuss key electrician interview questions and look at answers to some of these questions.

Electrician Interview Questions With Sample Answers

Most interviewers look for a combination of hard skills, behavioural skills and soft skills in an ideal candidate. Here are some electrician interview questions with their objectives and answers to help you prepare for your interviews:

Why did you decide to become an electrician?

Interviewers can often try to measure your passion for the profession, gain a better understanding of your background and education and how they pertain to the job for which you are applying. These basic electrician interview questions can take many forms and gauge your willingness to speak about your education, your interest in the job and your personal experiences in the field.

Sample answer: "I always knew I wanted to be a professional in this field. My father, whom I admired when I was little, was an electrician. Dealing with electricity can be tricky. With my on-the-job training, I think I possess the skills such as a thorough understanding of practical installation, electrical schematics, health and safety this job demands."

Can you describe some of your recent projects?

This question is to assure the interviewer of your understanding of how electrical systems work. You can focus on sharing your work experiences that align with the job description for which you are interviewing.

Sample answer: "I have dealt with three-phase corner grounding delta power cables, used by my former company for cost-effectiveness. I made the use of a service cable with two insulated conductors deviating from the standard three used in a three-phase service entrance. I have also worked with insulation fault problems and fixed a grounding phase for a building in my last project as a residential electrician."

According to you, what are the three qualities that make for a competent electrician?

Questions like these test whether the candidate is a right fit for the organisation. A good prospect can answer this question based on their experience and skills.

Sample answer: "A good electrician has to have an innate sense of mechanics to be comfortable and safe around electrical components and machinery. Diagnosing and repairing electrical defects covers a large part of an electrician's work; having strong problem-solving skills is also necessary to investigate and come up with alternate solutions. Alongside that, excellent customer service skills can help electricians to communicate with individuals at residences and companies and make them understand the situation and consequences."

What are your specific areas of expertise in electricity?

This question aims at understanding the candidate's education, experience and expertise. Your answer can help interviewers judge and assess if your experience matches the company needs and aspects of the job role.

Sample answer: "I have worked as an industrial electrician during most of my career. I diagnose and fix defects with wiring and components in industrial electrical systems. I have experience in training apprentices and handling large tools and equipment. I can attribute my experience to working on new construction and maintaining electrical systems."

What safety procedures do you follow at work?

Working with electricity is not always easy, as it exposes electricians to daily job hazards. This question shows the willingness of the candidate to follow safety protocols at work alongside their preparedness.

Sample answer: "I have been following the occupational health and safety guidelines early on, which helps me keep safe and ensure others' safety as well. I wear reliable gear and use flame-retardant equipment at work. I have attended on-the-job training sessions, which instilled in me the importance of safety practices like using a multimeter to test the strength of the current in electrical components."

What techniques do you use for time management, and why do you think this is important?

Your interviewer is interested in your efficiency in completing your tasks, which can have implications for other tasks as well. A qualified electrician may coordinate schedules with other crews, including plumbers, painters and carpenters on site. Time management is one of the skills most recruiters look for in a competent candidate.

Sample answer: "I focus on measurable and actionable results by implementing a standardised approach. That involves preparing detailed drawings to keep a count of size conduits, routing and cables and setting up a communication protocol for other stakeholders to finish the work on time."

How can you prevent the failure of high voltage electrical systems?

This is a general question where the interviewer expects specific and concise answers. They also place equal importance on theoretical knowledge, technical skills and communication skills.

Sample answer: "The maintenance of high-voltage electrical systems requires frequent inspections and safe operational procedures. It is important to ensure that the circuitry is not overloaded and that everything connected to the system has the proper voltage and current. Alongside, we inspect the system for worn or damaged components on the system."

Can you describe the difference between a breaker and a fuse for me?

Interviewers often ask electricians questions that are technical or operational in nature. The best way to approach them is to be brief and concise.

Sample answer: "Breakers and fuses are both designed to interrupt the flow of electrical current. The difference is that a fuse can only operate once as it breaks down when it interrupts current, whereas breakers are similar to switches and can be reset. Fuses are no longer used in buildings and are mostly present in electrical appliances or vehicles."
