Working Near Ausgrid Powerlines: Safe Approach Distances Explained Simply

If you've ever wondered why a painter refused to work near the powerline at the front of your house, or why a tree-trimming crew stopped and made a phone call before touching a branch, the answer sits in Ausgrid's Electrical Safety Rules. The current version (2026/1) sets minimum distances that different people must keep from live electrical equipment — and for most of us, those distances are bigger than you'd guess.

On, near, and in the vicinity

Ausgrid's rules divide the space around live equipment into zones. Work "on" equipment means touching it. "Near" means inside the tight safe working distance that applies to trained and authorised people. "In the vicinity" is the outer zone — and it's governed by the distance that applies to ordinary persons, which is the category almost everyone reading this falls into. An ordinary person is anyone without specific electrical authorisation and training: homeowners, painters, roofers, landscapers, most builders.

The three-metre rule

For an ordinary person, the minimum safe working distance from live exposed equipment on Ausgrid's network is 3.0 metres. That's not advisory — it's the boundary that defines whether you're allowed to be doing what you're doing at all. If a job at your place would put a person, a tool, a ladder or anything they're holding within three metres of the service line or street mains, it isn't a job for an ordinary person any more. It needs someone with the right authorisation, or it needs the line isolated first.

Machinery has its own rules

Cranes, excavators, elevated work platforms and other mobile plant get their own table in Ausgrid's rules, because a machine can close three metres of distance a lot faster than a person on a ladder. For an operator without specific training or authorisation, the minimum approach distance to live overhead lines is 3.0 metres for the distribution voltages you'll see in Sydney streets, rising to 6.0 metres and beyond for the big transmission lines. Trained and authorised operators can work closer, but only with a dedicated safety observer whose entire job is to watch the machine while it moves. If your builder says the crane can't lift over the powerline without Ausgrid involved, this table is why.

Even the professionals have limits

A detail that surprises people: the safe approach distances don't drop to zero for the professionals. Ausgrid's rules set absolute limits of approach that even trained workers must never cross while equipment is live — 0.4 metres for the common distribution voltages up to 33kV, increasing with voltage. Getting closer than that means the line has to be isolated and proven de-energised first, through Ausgrid's formal network access process. So when work at your property requires a planned outage, it's not over-caution; it's the only lawful way to do the job.

Fallen wires: the eight-metre rule

One more number worth memorising, because it can save a life after a storm: stay at least 8 metres away from any fallen or dangling wire, and treat it as live until Ausgrid confirms otherwise. Wires don't always spark or hum when they're energised, and the ground itself can be dangerous around a fallen conductor. Keep people and pets back, and call Ausgrid's emergency line on 13 13 88.

What to do when a job gets close to the lines

The practical takeaway for Sydney homeowners is simple. Before any work near your overhead service — painting the fascia, replacing gutters, putting up scaffolding, trimming a tree, lifting materials by crane — look up and measure honestly. If the work comes within three metres of live equipment, stop and get advice before anyone starts. Sometimes the answer is as simple as having the service line temporarily disconnected and reconnected by a Level 2 electrician, which is a routine, same-week kind of job. That's a far better outcome than a serious incident, and considerably cheaper than the consequences of getting it wrong.
