0433 462 902 Book Online

Total power loss in a Sydney home is caused by an Ausgrid or Endeavour Energy network outage, or a fault in your consumer mains, point of attachment, or service fuse. Exposed consumer mains or a failed service fuse is a shock and fire hazard — book a Level 2 ASP electrician or call 0433 462 902 for immediate response. If your neighbours have power and you don’t, the fault is on your side of the meter and requires a Level 2 ASP licensed electrician, not your energy retailer. Sydney Electrical Service is dispatched 24/7 across every metropolitan suburb. If the whole street is out, call Ausgrid on 13 13 88 first.

What This Fault Means

The supply path to your home moves through several discrete stages. A break at any one of them means no power:

Network supply — Ausgrid (most of Sydney) or Endeavour Energy (Western Sydney, Blue Mountains, Illawarra)
Point of attachment — where overhead service mains attach to your roof or wall
Service fuse — the network-owned fuse in or near your meter box
Consumer mains — the cables from the service fuse to your main switch (your responsibility)
Main switch — the master isolator inside your switchboard
Main neutral — the return path; a broken main neutral causes severe voltage problems
Distribution board — the busbar feeding individual circuit breakers and RCDs

The first four stages are network or Level 2 ASP territory. The last three are inside your switchboard. The investigation order matters: start at the meter and work inward.

Common Causes

A network outage affecting your street or feeder — confirm via Ausgrid or Endeavour Energy outage map
A blown service fuse caused by an overload or short-circuit on the consumer mains
A damaged or detached point of attachment after wind, branches, or vehicle impact
A failed main switch in your switchboard
Corroded or burnt main switch terminals — common in coastal Eastern Suburbs and Northern Beaches homes
A broken main neutral (very dangerous — see below)
Aged consumer mains with cracked PVC insulation
Storm damage to overhead lines or service cabling
Possum or bat damage to overhead leads (more common than people realise in tree-heavy suburbs)
A burnt-out smart meter or meter terminal
Water ingress into the meter box after horizontal rain
Solar PV inverter trip-out cascading through a poorly designed switchboard

Is It Dangerous?

A house with no power is not in itself dangerous — but several of the underlying causes are extremely so. Watch for:

Red flags — call immediately if you see any of these:

**A broken main neutral** — symptoms include partial power, lights dimming when appliances run, electronics buzzing or behaving erratically, and shocks from metalwork. Stop using the installation.
A burning, plastic, or "hot wire" smell anywhere near the meter box
Smoke or scorching at the meter or switchboard
A buzzing or humming meter
Hot tingles from any tap, sink, or appliance — points to a neutral or earthing fault
Visible damage to overhead consumer mains (sagging, broken, or contacting trees)
Sparks at the point of attachment

What to Do Right Now

Check whether the outage is local or network-wide. Look at your neighbours' lights or check the Ausgrid (13 13 88) or Endeavour Energy outage map online.
If it's a network outage, wait. Crews will restore power. We cannot help with network-side faults.
If your neighbours have power, the fault is on your installation.
Open the switchboard. Check whether the main switch is in the OFF or middle (tripped) position.
Try to reset the main switch once. If it holds, leave it alone and monitor for returning faults.
If it won't hold, do not force it. Leave the main switch OFF and call us.
Check the meter box for visible damage — burning, smoke, water, exposed cables, blackening.
Photograph anything visible so we can dispatch with the right parts.
If you smell burning or see smoke, evacuate and call 000 followed by us on 0433 462 902.

When You Must Call a Licensed Electrician

Call Sydney Electrical Service on 0433 462 902 if:

The outage is your house only (neighbours have power)
The main switch will not stay reset
You can smell burning or see scorching at the meter or switchboard
Overhead consumer mains are visibly damaged
The point of attachment has been hit by a tree, branch, or vehicle
You have unusual symptoms — partial power, flickering, lights brightening or dimming randomly
You feel a shock or tingle from any metalwork (a serious main-neutral warning)
Your meter box shows water, soot, or burn marks
Storm damage has affected your supply

We are licensed Level 2 ASP contractors. We can attend, isolate, and repair point-of-attachment, service-fuse, and consumer-mains faults — work most general electricians cannot legally undertake — in a single visit, including reconnection coordination with Ausgrid where required.

Why DIY Is Dangerous and Illegal in NSW

Work on the consumer mains, service fuse, point of attachment, or main switchboard is reserved for licensed electrical contractors and Level 2 ASPs under NSW law. The reasons are not bureaucratic:

The supply side carries un-fused current direct from the network
Service fuses can deliver tens of thousands of amps into a fault before they blow
An arc flash at the meter can deliver lethal energy in milliseconds
A broken main neutral can leave consumer-side metalwork at full mains voltage relative to true earth
Overhead lines may be live even when the main switch is off

The *Service and Installation Rules of NSW* set out exactly which work falls under Level 2 ASP authority — and a homeowner attempting any of it is committing an offence under the *Gas and Electricity (Consumer Safety) Act 2017*. Insurance for fire or fatality will be void. Conveyancing inspections will identify and report the work.

Frequently Asked Questions

How do I know if it's a network outage or my problem?

Look at your neighbours and the streetlights. If they have power and you don't, the fault is on your installation. If everyone is out, it's a network outage — call Ausgrid (13 13 88) or Endeavour Energy.

What's a service fuse and where is it?

The service fuse is the network-owned fuse usually located in your meter box, typically marked "ENERGEX" or "Ausgrid" or simply "MAIN" with a porcelain body. It protects the supply cable into your home. Replacing it requires a Level 2 ASP — this is not homeowner work.

What's a "broken main neutral" and why is it dangerous?

The neutral conductor returns current to the network. When it breaks, voltage relative to earth becomes unstable — appliances may receive 0 V or up to 415 V, lights flicker, electronics fail, and metalwork can become live. It is one of the most dangerous faults in domestic electrical work.

Why might the main switch trip with nothing obvious going on?

A blown breaker downstream, a major fault in any subcircuit, water in the switchboard, or a failed main switch itself can cause this. The main switch is rarely the actual fault — it is usually responding to something else.

Should I call Ausgrid or an electrician?

Call Ausgrid if neighbours are out (network) or if there is visible damage to network-owned infrastructure. Call us if your house alone is out, the meter box shows damage, or your main switch won't reset. We can liaise with Ausgrid as part of the job.

Can a storm cause total power loss?

Yes — wind brings down overhead lines, rain forces water into compromised seals, and lightning damages service equipment. Sydney's east-coast lows during October–March are responsible for hundreds of outage callouts every year. See No Power After Storm.

Could solar cause my power loss?

A failed inverter or DC isolator typically affects only the solar circuit, not the whole house. A poorly installed solar system can occasionally cascade a fault back through the main switchboard — we see this in older 2010-era installs in particular.

How quickly can you get to me?

We dispatch 24/7 across all Sydney suburbs. Typical emergency response is 30–90 minutes; during major storms it can stretch to 2–4 hours. Call 0433 462 902 for a real-time ETA.

Is it safe to stay in my house while I wait for an electrician to arrive?

In most cases it is safe to remain at home, but keep your meter box closed and do not attempt to touch any wiring or service equipment. Avoid using candles as a substitute for lighting — the risk of fire without working smoke alarms is real — and keep your fridge and freezer shut to preserve food during the outage.

Can I replace the service fuse or fix the consumer mains myself to get the power back on?

No — it is illegal in NSW for anyone other than a Level 2 ASP licensed electrician to work on service fuses, consumer mains, or anything on the network side of your meter. Attempting it yourself risks a fatal electric shock and can void your home insurance.

What's the difference between a Level 2 ASP electrician and a regular electrician?

A Level 2 Accredited Service Provider holds an additional licence issued under NSW energy network rules that permits work between the street supply and your meter — consumer mains, service fuses, and the point of attachment. A standard electrician's licence does not cover this work, which is why Ausgrid and Endeavour Energy will not attend a fault on the customer side of the meter.

How much does it cost to repair consumer mains or replace a service fuse in Sydney?

The price varies depending on the extent of damage, access difficulty, and materials required, so there is no single fixed figure. Call 0433 462 902 and Sydney Electrical Service will assess the fault and provide a firm, fixed-price quote before any work begins.

Should I worry if only half my house has power — some lights work but others don't?

Yes, treat this as urgent — partial power loss where some circuits work and others don't is a classic sign of an open or broken neutral in your consumer mains, which can push dangerously high voltages onto appliances still running. Switch off sensitive equipment at the powerpoint and call a Level 2 ASP electrician immediately rather than waiting to see if it resolves on its own.
