Electrician job description and duties

Updated 16 September 2026 · 2 min read

An electrician makes sure buildings and equipment have safe, reliable electrical power. Depending on the employer, the role may focus on new installations, on maintaining existing systems, or on both. The duties below are common to most electrician posts, whether with a contractor, the utility, a factory or the maintenance team of a public institution.

How this guide was made

Written for this site with AI assistance, then checked automatically before publishing. The topic table, sample questions, worked examples and study plan are generated from this site’s question bank: each worked example is recalculated by separate code, and each sample answer says where it came from.

The guide deliberately states no salaries, grades, pass marks or exam dates. Those change, and they could not be checked here, so take them from the advert itself.

Purpose of the role

The role exists to deliver electrical installations that work and harm nobody, and to keep them in that condition. Every task, from wiring a socket to replacing a distribution board, is judged by two questions: does it do what it should, and is it safe for the people who will use it?

Installation duties

Read drawings and specifications, and plan the work.
Install containment, cables, accessories, distribution boards and protective devices.
Connect lighting, sockets, motors and other equipment.
Install earthing and bonding.
Label circuits and equipment clearly.
Leave the work area safe and tidy at the end of each day.

Maintenance and repair duties

Maintenance electricians carry out planned inspections, test protective devices, tighten connections, replace worn components and respond to breakdowns. They diagnose faults such as tripping breakers, dead circuits and overheating equipment, repair them safely and record what they found. In larger organisations they follow a maintenance schedule and work orders from a maintenance management system.

Testing and certification

Before new or altered work is energised, the electrician carries out the required tests and records the results. Test records show the work is safe and give a baseline for future maintenance. Some posts also include periodic inspection of existing installations and reports on their condition.

Safety responsibilities

Electricians follow safe isolation procedures every time, use the correct protective equipment, assess risks before starting and stop work when conditions are unsafe. They also protect other people: cordoning off work areas, warning occupants about interruptions and never leaving exposed live parts unattended.

Working relationships

On construction sites, electricians work with site managers, engineers and other trades. In maintenance roles, they work with facility managers, the people who use the building and suppliers. Electricians usually report to an electrical supervisor, a maintenance manager or an electrical engineer.

How performance is judged

Electricians are judged on the quality and safety of their work, whether installations pass inspection and testing first time, how quickly and reliably faults are fixed, the accuracy of their records and their safety record. Punctuality and good relations with customers and colleagues count as well.

Common questions

What is the difference between an electrician and an electrical technician?

The roles overlap. An electrician focuses on installing and maintaining wiring and equipment, while an electrical technician often supports engineers with testing, commissioning and technical documentation. Titles vary between employers.

Do electricians work outdoors?

Often. Site work, external lighting, supply connections and utility work all happen outdoors, sometimes at height, so weather and safe access are part of planning each job.
