A Beginner’s Guide to Electrical Supply Industry Roles

The electrical supply industry (ESI) plays a critical role in powering homes, businesses, and also infrastructure across New South Wales. Behind every connection point and powerline is a team of trained professionals who keep the system running safely and reliably. If you’re considering a career in this industry or perhaps trying to understand the different pathways available, it helps to know how each role contributes to the bigger picture.

In this guide, we’ll break down the key ESI roles in NSW, what they involve, and the training required to get started.

ASP Level 1 – Network construction and asset installation

Accredited Service Providers (ASPs) are licensed to work on or near the electrical distribution network. ASP Level 1 workers are responsible for constructing the actual infrastructure that carries power — such as power poles, overhead lines, substations and underground cables.

These workers are usually employed by civil or electrical contractors and complete large-scale works under network authority instructions. Their work is essential in new subdivisions, infrastructure upgrades, and network extensions.

To become an ASP Level 1 worker, you’ll need to complete accredited training and obtain authorisation from the NSW Department of Planning and Environment.

ASP Level 2 – Service connections and metering

ASP Level 2 electricians perform work that connects private properties to the electricity network. This includes disconnecting and reconnecting power, upgrading service lines, installing meters and energising installations.

This is a high-risk role that requires specific technical skills and strict compliance with safety procedures. ASP Level 2 work is further divided into classes:

• Class 2A: Disconnect and reconnect at the point of attachment
• Class 2B: Underground service work
• Class 2C: Overhead service work
• Class 2D: Metering

To work in this space, you must hold a current electrical licence and complete nationally recognised ASP Level 2 training, followed by formal authorisation.

Lineworkers and cable jointers

Lineworkers focus on the construction and maintenance of overhead powerlines, while cable jointers handle underground electrical cables. These are physically demanding roles that often involve working at height or in confined spaces.

Both require a high level of technical skill and a strong understanding of electrical safety. Lineworkers and jointers usually work for network providers or major contractors and must complete specific ESI training, including high-voltage rescue and pole-top rescue.

Crane and plant operators working near live assets

While not electricians, crane and plant operators are essential to many ESI worksites — especially when their equipment operates near live powerlines. These workers must understand safe approach distances, exclusion zones, and emergency procedures.

IAC’s crane and plant training equips operators with the safety knowledge required to work in proximity to overhead electrical assets.

Non-electrical workers in the ESI

Many other workers play a role on ESI sites — including spotters, civil contractors, and also machine operators. Even though they’re not carrying out electrical tasks, they still need to understand the risks of working near live infrastructure.

Overhead powerlines training and low voltage rescue training are mandatory for many non-electrical roles in the industry. These units help ensure that everyone on site can recognise electrical hazards and respond appropriately.

Starting your pathway in the ESI

If you’re new to the industry, start by identifying what kind of work interests you. From there, you can explore the required licences, qualifications and safety training.
