What & Why
What Are Consumer Mains?
Your consumer mains are the cables that carry electricity from the point of attachment — where the network supply physically connects to your property — all the way to your main switchboard. Depending on the age and style of your home, they’re either running overhead from a power pole down to the eaves, or underground from a pit in the footpath up into the building.
They’re the bottleneck of your entire electrical system. Switchboard, wiring and appliances can all be perfectly modern, but if the consumer mains are undersized, you’ll get voltage drop, nuisance tripping, premature appliance wear, and an installer telling you they can’t commission your new solar inverter or EV charger.
Most homes in Bondi, Randwick, Paddington and across the older parts of the Eastern Suburbs were originally fitted with 4mm² or 6mm² consumer mains — fine for a 1970s household with a TV, a fridge and an electric kettle. Today, the same house might have ducted air-con, an induction cooktop, instantaneous hot water, a pool pump, an EV charger and a 6.6kW solar inverter. The cables simply weren’t designed for it. A consumer mains upgrade replaces them with cable correctly sized to AS/NZS 3008 for your actual load.
Warning Signs
Six Signs You Need a Consumer Mains Upgrade
Some of these are inconvenient. Some will block your next major install. A couple are genuine safety risks.
Lights dimming under load
When the air-con starts, the oven cycles, or the pool pump kicks in, you see the lights briefly dim. That’s voltage drop — the classic signature of consumer mains that are too small for the load.
Solar install rejected or limited
Your solar installer says you can’t put a 10kW system on this property, or your inverter keeps tripping on over-voltage. Often the consumer mains need upgrading before the system will work to spec.
Planning an EV charger
Single-phase 7kW chargers and any three-phase 11–22kW charger will likely max out older 4mm² or 6mm² consumer mains. Most EV installers will mandate an upgrade before commissioning.
Defect notice from Ausgrid
Ausgrid issues defect notices for consumer mains that are damaged, undersized, deteriorated, or attached unsafely. You usually have 21 days to rectify. We handle defect repairs end-to-end.
Visible cable damage or aging
Cracked outer sheath, exposed conductors, sun-damaged insulation, rusted attachments at the eaves, or old rubber-insulated cable that’s decades past its design life. All require replacement, not patching.
Renovating or extending
Major renovations almost always increase electrical load — new kitchen circuits, en-suites, study lighting, granny flat. Upgrading the consumer mains during the reno is far cheaper than retrofitting later.

What’s Included
A Complete Mains Upgrade
A consumer mains upgrade isn’t just running a new cable and calling it a day. It’s a coordinated job that often involves your switchboard, the point of attachment, Ausgrid, and (if going underground) trenching across your property.
Every consumer mains upgrade we deliver includes:
- Free on-site assessmentWe come out, inspect your existing mains, measure the run, calculate the correct cable size for your present and future loads, and provide a fixed-price quote.
- Load calculation to AS/NZS 3008Cable sizing isn’t guesswork — we calculate the required cross-sectional area based on your maximum demand, run length, installation method and voltage drop allowance.
- Ausgrid coordinationIf the upgrade requires a network shutdown or change to the point of attachment, we lodge the paperwork and book the outage with Ausgrid on your behalf.
- Overhead or underground installationReplacement run completed as overhead (faster, cheaper) or underground (cleaner, more durable). We discuss the trade-offs and let you choose.
- Trenching and ducting (underground installs)Excavation, conduit installation, cable pulling, backfill and site reinstatement. We restore the surface as close to original as possible.
- Point of attachment upgradeIf your eave attachment or pit termination is failing, deteriorated, or non-compliant, we replace it as part of the same job.
- Connection to switchboardTermination at the main switch with correct-sized lugs and torque-verified connections. Switchboard tails replaced if they’re also undersized.
- Full testing & verificationInsulation resistance, polarity, earth continuity, voltage drop under load — the complete test sequence before energising.
- CCEW & network paperworkCertificate of Compliance Electrical Work plus any required network operator notifications lodged and copies provided.
Our Process
How a Consumer Mains Upgrade Runs
Five clear steps from your first call to power back on with the new cable.
Call & book site visit
Tell us about your home, what’s prompting the upgrade (solar, EV, defect, renos), and your suburb. We book the free on-site quote.
On-site quote
We measure the run, inspect the existing cable and point of attachment, calculate the correct new size, discuss overhead vs underground, and leave a fixed-price quote.
Schedule & Ausgrid liaison
Job booked. If a network shutdown is required, we coordinate with Ausgrid for the outage window — typically 1–2 weeks ahead.
Install the new mains
New cable installed (overhead or underground), point of attachment renewed if needed, terminated at both ends. Power off for a few hours on the day.
Test, energise, certify
Full test sequence, energise, verify voltage and load. CCEW emailed the same day.

FAQs
Consumer Mains Questions, Answered
The questions Eastern Suburbs homeowners ask us most often before booking a mains upgrade.
Where exactly do consumer mains start and end?
They start at the point of attachment — the bracket or termination where the network supply physically meets your property (the eave for overhead, the pit for underground). They end at the main switch in your switchboard. Everything from the street to the point of attachment is Ausgrid’s responsibility; everything from the point of attachment inward is yours.
Why would my consumer mains need upgrading?
The four most common triggers: (1) you’re installing solar, an EV charger or three-phase ducted air-con and the existing cable can’t handle the load; (2) you’ve received an Ausgrid defect notice; (3) you’re experiencing voltage drop, dimming lights or appliance issues; (4) the existing cable is physically damaged, deteriorated, or simply too old.
How is the correct cable size decided?
We calculate it to AS/NZS 3008 based on your maximum demand (present and future), the run length, the installation method (overhead, underground, in conduit), ambient temperature, and the maximum permitted voltage drop. Typical residential outcomes: 16mm² for an average home, 25mm² or 35mm² for larger or EV-ready installations, often three-phase for future-proofing.
Do I need to be home for the work?
Someone needs to be on-site at the start to confirm the scope and let us access the meter and switchboard. After that you’re welcome to leave — we send updates by phone or text and let you know when power is back on.
Will my driveway need to be dug up?
Only if you choose an underground installation and the cable run crosses a hard surface. We discuss overhead vs underground options during the quote so you know exactly what’s involved. Where trenching across paving or concrete is required, we reinstate the surface as close to original as possible, or coordinate with a tiler/concreter if you want a premium finish.
Does Ausgrid need to be involved?
Often yes — if the upgrade requires a network shutdown, a change to your point of attachment, or a phase change (single to three phase), Ausgrid needs to coordinate. As Level 2 ASPs we lodge the paperwork and book the outage on your behalf, typically 1–2 weeks ahead. You don’t need to call them yourself.
Is this covered by my home insurance?
If the upgrade is the result of damage — storm, lightning, fire, vehicle impact — your insurance often covers it. We provide detailed photos, reports and itemised invoices to support your claim. For voluntary upgrades (solar, EV, renovation-driven), it’s typically an out-of-pocket cost.
Can I do the consumer mains upgrade together with a switchboard upgrade?
Yes — and we recommend it where both are needed. Doing them in one visit saves you the cost of a separate power outage, a separate Ausgrid booking, and a separate compliance process. Combined jobs are typically 15–20% cheaper than the same scope done separately.
