Endeavour Energy network, acreage & Level 2

Hills District Electrician

Out here the enemy is heat rather than salt, the blocks are measured in acres rather than metres, and you are not on the Ausgrid network. Three differences that change almost everything about the job.

Worth knowing first

You are not on the Ausgrid network out here

Most Sydney electricians spend their working lives on the Ausgrid network. Cross the line into Greater Western Sydney and you are dealing with Endeavour Energy instead, and the Hills District sits squarely inside it.

The wiring rules themselves do not change. AS/NZS 3000 is national and a circuit is a circuit. What changes is everything that touches the network side of the job: the connection application, the forms, the metering arrangements, the notice periods, the inspection process and who you talk to when something needs approving. It is not harder, it is just different, and different is where delays come from when somebody is learning it on your job.

It matters most on the work that is worth the most to you. A supply upgrade, a new connection on a vacant block, a meter relocation, a private pole replacement or a defect notice are all network-side jobs. Get the distributor wrong at the quoting stage and you find out weeks later, usually while the concrete is waiting.

The scale is worth understanding too. Endeavour covers 24,800 square kilometres and 2.8 million homes and businesses, from Greater Western Sydney out to the Blue Mountains, the Southern Highlands, the Illawarra and the South Coast. It runs around 300,000 poles of its own, and there are roughly another 100,000 privately owned poles on customers' land inside that network. On acreage in the Hills, a good number of those are in somebody's paddock, and most owners have no idea they own them.

So the first question we ask about a Hills job is often not what you want done. It is whether any of it touches the network, because that decides the process, the timeline and who has to be involved.

Heat

On the coast the problem is salt. Out here it is load

The Hills sits between Parramatta and Richmond, and that position on the map is the single biggest influence on what fails and when.

Scroll to see the full chart →

What it means: coastal Sydney averaged about 4.4 days a year over 35 degrees in the decade to 2017. The western Sydney average across five measuring sites was 15.4 for the same decade, roughly three and a half times as many, and higher than every one of those sites' long-term averages. The Hills is not itself one of the measured sites and sits geographically between Parramatta and Richmond, so read it as somewhere in that band. In January 2018 Penrith reached 47.3 degrees on a day Observatory Hill managed 35.

None of that is a weather report. It is a load profile. On a 40 degree afternoon every air conditioner in the street runs continuously for hours, pool pumps run, and everything upstream of them, the consumer mains, the main switch, the busbar and every termination in the board, carries that current and heats up while doing it.

Heat is what turns a marginal connection into a failed one. A slightly loose termination has a small resistance, a small resistance under high current makes heat, heat makes the joint worse, and the worse joint makes more heat. That loop runs slowly for years and then finishes quickly on the hottest week of the year, which is exactly when you cannot get anyone out and exactly when you least want to be without air conditioning.

It is also why we are blunt about thermal inspection and switchboard condition out here in a way we would not be for a shaded terrace in the inner west. The same board with the same faults simply has an easier life closer to the water.

Local conditions

Six things about the Hills that change the job

Every one of these turns up in a normal working week out here, and none of them is true of the suburbs closer to the harbour.

Summer is when things break

A hot week is a stress test that the whole installation sits through at once. Ducted air conditioning runs for hours rather than minutes, the pool pump runs, and every termination between the pole and the appliance carries that current continuously.

Faults that would stay dormant in a cooler suburb come to the surface here. Discoloured terminations, a main switch that is warm to the touch, breakers tripping in the afternoon and not the morning. All of it is worth looking at in spring rather than discovering in February.

Private poles, and a lot of them

Endeavour has around 100,000 privately owned poles sitting on customer land across its network, and acreage at Dural, Kenthurst, Glenorie, Annangrove and Maraylya is exactly where they live. If the pole is past the connection point it is yours, along with the wires and the job of keeping vegetation three metres clear.

Endeavour recommends inspecting before bushfire season and after major storms. If they find a defect you get a Report of Inspection with a timeframe, supply can be disconnected if it is not rectified, and in bushfire areas they may do the work and recover the cost from you.

Distance changes the cable, not just the price

A run out to a shed, studio, stables, pump or gate on an acre block is a voltage drop problem before it is a current problem. Size it on load alone and the cable will pass every calculation and still arrive with too little voltage left to start a compressor properly.

Motors are the ones that suffer, because a motor starting on low voltage draws more current, runs hotter and dies early. We size these from the actual measured distance and the actual load, which is slower to quote and considerably cheaper to own.

The supply was sized for a smaller life

A common single-phase supply gives the whole property about 14.5 kW. A single-phase car charger at 32 amps takes roughly 7.4 kW of that by itself, and a second one would take essentially all of it. Add ducted air conditioning, a pool, electric hot water and an induction cooktop and the sums stop working.

Three phase is often the answer and usually runs $3,000 to $8,000 depending on how far the supply has to come and what the board needs. Sometimes it is not the answer yet, and load management is cheaper. Worth calculating rather than assuming in either direction.

The rural north is bushfire country

Glenorie, Maroota, Wisemans Ferry, Kenthurst and Annangrove back onto bush, and where land is mapped as bush fire prone, new work and substantial alterations bring AS 3959 and Planning for Bush Fire Protection into the design, with requirements following from the Bush Fire Attack Level.

There is a practical side beyond paperwork. A house on tank water with an electric pump has no water when the power goes off, which on a bad day is precisely when it matters. It is a conversation worth having before the season rather than during it.

Three completely different housing stocks

The Hills is not one vintage. There is the 1970s and 1980s brick through Baulkham Hills, Castle Hill, Winston Hills and West Pennant Hills, much of it now on its second or third round of additions. There are the estates from Kellyville north, built for a household that has since grown.

And there is the rural north, where houses were often owner-built, extended over decades, and carry a mixture of everything. Each of the three needs a different first question, and quoting them the same way is how people get surprised.

By area

What the houses are, and what usually goes wrong

Broad strokes, with exceptions in every street, but this is the pattern.

Where	Typical housing	Lot size	What we get called for
Baulkham Hills, Winston Hills, North Rocks	1970s and 1980s brick, heavily added to	Suburban	Switchboard upgrades, ageing consumer mains, air conditioning circuits, renovation rewires
Castle Hill, West Pennant Hills, Cherrybrook	Larger 1980s onward brick, established gardens	Suburban to generous	Ducted air conditioning supply, pools, outdoor areas, supply capacity for additions
Bella Vista, Norwest, Beaumont Hills	Newer executive housing near the business park	Suburban	Car chargers, home offices, data and cameras, three-phase upgrades
Kellyville, North Kellyville, Rouse Hill, Box Hill, Gables	Recent estates, dense and still building	Compact	Adding what the build left out. Chargers, pools, second air conditioners, switchboard capacity
Dural, Kenthurst, Glenhaven, Annangrove	Acreage. Houses, sheds, studios, stables	Acres	Private poles, long underground and overhead runs, shed and pump supply, gates
Glenorie, Maroota, Maraylya, Cattai	Semi-rural and rural, often owner-built and extended	Large acreage	Everything on the acreage list, plus bushfire zone work and supply reliability
Wisemans Ferry, Sackville North, Lower Portland	Riverside and rural, genuinely remote	Very large	Long runs, standby arrangements, pumps, and jobs planned in one visit rather than three

The pattern worth noticing is that the two ends of the Shire fail for opposite reasons. In the older suburbs the installation is tired and the household has grown into it. In the new estates the installation is perfectly sound and was simply specified for the house as it was handed over, before the pool, the charger and the second air conditioner arrived.

Neither is a fault as such. Both end up at the same place, which is a switchboard and a supply that need to be looked at as a whole rather than asked to absorb one more circuit.

Acreage

When the job is measured in hundreds of metres

Working on acreage is a different trade from working in a suburb, and the difference is not really the size of the house. It is that the electrical installation stops being a thing inside a building and becomes a thing spread across a property.

There is usually a private pole or several, with overhead lines crossing a paddock or a driveway that are yours to maintain. There is a shed, and the shed has its own board, and that board was probably fed by whatever cable was on the roll at the time. There is a pump, on a bore or a tank or a dam, which is a motor doing hard work a long way from the source. There may be stables, a studio, a workshop with a welder, a gate at the road with its own supply, and lighting along a driveway that is longer than most streets.

Each of those is a voltage drop calculation, a protection decision and an earthing question in its own right. Get any of the three wrong and the symptom is not a dead circuit. It is a pump that runs hot, a welder that will not strike properly, a gate that works in winter and not in summer, or an earthing arrangement that is fine until the day it matters.

It also changes how a visit should be run. Driving out to Maraylya to change one fitting is not sensible for either of us. We would rather walk the property once, list everything, and do it in one go.

How it got here

A short history that still shows up in your switchboard

The Hills went from orchards to outer suburb to metro corridor in about a century, and each wave left a different installation behind it.

1923

The railway reaches Castle Hill

A line from Parramatta opens to Castle Hill in 1923 and is extended to Rogans Hill the following year. The decision to convert it from a tramway had been taken in 1919 specifically to encourage estates to be subdivided for housing, which tells you what the district was expected to become long before it did.
1932

And loses it again

The line closes on 31 January 1932. Stations were awkwardly spaced and passengers preferred the new motor buses, which went where people actually wanted to go. The Hills spends the next eighty-odd years as car country, which is why the road pattern and the lot sizes look the way they do.
1970s

Brick and tile arrive in bulk

Baulkham Hills, Castle Hill, Winston Hills and West Pennant Hills fill in with the brick housing that still makes up much of the middle of the Shire. Sound construction, sensible for its day, and specified for a household with one car, no pool and a single wall-mounted air conditioner if any.
2015

The boundary moves

A boundary review transfers several southern suburbs from The Hills Shire to the City of Parramatta, taking the Shire from about 401 to 386 square kilometres. Worth knowing when a search result tells you a suburb is or is not in the Hills, because plenty of published information still uses the old line.
2019

The metro opens

Sydney Metro Northwest starts carrying passengers on 26 May 2019, with eight stations through the Hills at Tallawong, Rouse Hill, Kellyville, Bella Vista, Norwest, Hills Showground, Castle Hill and Cherrybrook. Density arrives around the stations, and a district built entirely around cars starts building apartments.
2021

191,876 people, and still growing north

The census counts 191,876 residents across 386 square kilometres, with the growth concentrated in the newest estates at North Kellyville, Box Hill and Gables while the rural north stays rural. One Shire, two entirely different electrical worlds, and both of them ours.

What we do here

The jobs the phone rings about in the Hills

Not a generic service list. This is what actually comes in from this part of Sydney.

Private poles and supply upgrades

Defect notices, pole replacements and consumer mains that were sized for a smaller house. Network-side work on the Endeavour system, which is Level 2, so it does not have to wait for a second trade.

Consumer mains & Level 2

Switchboards that run hot

Summer finds every weak termination in the board. Replacing tired protection with RCBOs gets you proper shock and fault protection, and gives a charger, surge protection or a new circuit somewhere sensible to live.

Switchboard upgrades

Hot water and controlled load

Big houses, big tanks and a tariff decision most people never revisit. Whether the system suits the supply, and whether the controlled load wiring still matches how the household actually uses hot water.

Hot water installation

Pool and spa compliance

Zones, equipotential bonding and RCD protection, plus the pump circuit itself, which on a hot week is running at the same time as everything else in the house. Very common through Castle Hill and the acreage belt.

Pool electrician

Rewiring and renovation

The 1970s and 1980s stock through the middle of the Shire is now on its second or third renovation, and the wiring is usually the part nobody budgeted for. We stage it so you are not living on a building site.

Electrical rewiring

Data cabling and cameras

Big footprints and thick walls make Wi-Fi struggle, and a driveway camera at the road is a long run. Registered cabling, done properly, with access points fed by cable rather than hoping.

Compliance

Licensed, accredited and certified

Licence 387609C Level 2 accredited & insured

Work is done to AS/NZS 3000 and certified. We lodge a Certificate of Compliance for Electrical Work within 7 days of testing, which since 1 July 2026 goes through the BCNSW eCert portal.

Level 2 accreditation is what allows work at the point of supply, and in the Hills that covers a lot: private pole replacements, service line work, supply upgrades, metering changes and new connections. It applies on the Endeavour network the same as anywhere else, and it is the difference between one contractor and a queue.

Where a property is mapped as bush fire prone, which takes in much of the rural north of the Shire, AS 3959 and Planning for Bush Fire Protection may apply to new work and substantial alterations depending on the Bush Fire Attack Level assessed. We raise it before quoting, because it changes a design rather than a price.

Good to know

Hills District electrical questions

Is the Hills District on the Ausgrid network?

No, and this is the thing that trips up electricians who normally work east of Parramatta. Greater Western Sydney, including the Hills, sits on the Endeavour Energy network rather than Ausgrid. It is a different distributor with its own connection process, its own forms, its own metering arrangements and its own inspectors. The wiring rules are national and do not change, but everything that touches the network side does. If you are getting a supply upgrade, a new connection, a meter change or a private pole replaced, you want somebody who deals with Endeavour regularly rather than somebody learning on your job.

Why does everything electrical seem to struggle in summer out here?

Because it is genuinely hotter, and by a wide margin. Coastal Sydney averaged about 4.4 days a year above 35 degrees over the decade to 2017. The western Sydney average for the same decade was 15.4, which is roughly three and a half times as many. On those days every air conditioner in the street runs at once, for hours, and everything upstream of them runs hot too. A switchboard with a marginal connection, an undersized consumer main or a tired main switch will get through a mild summer and fail in a hot one. It is not bad luck, it is the load finally finding the weak point.

Do I need three-phase power?

Sometimes, and it is worth working out before you commit rather than after. A common single phase supply is around 14.5 kW for the entire property. A single-phase EV charger at 32 amps takes about 7.4 kW of that on its own, and a second one would put you at roughly 14.8 kW, which is the whole supply. Add ducted air conditioning, a pool, an electric hot water system and an induction cooktop and the arithmetic stops working. Three phase typically runs $3,000 to $8,000 depending on how far the supply has to come and what the switchboard needs. We would rather calculate it properly than guess, because sometimes the honest answer is that you do not need it yet.

Who owns the power pole on my acreage?

You do, along with the wires from it, if it is a private pole, and there are a great many out here. Endeavour Energy has roughly 300,000 poles of its own and around another 100,000 in private ownership across its network. Everything past the connection point on your land is yours to maintain, including keeping vegetation at least three metres clear of the lines. Endeavour recommends inspecting before bushfire season and after major storms. If a defect is found you get a Report of Inspection and a timeframe, supply can be disconnected if it is not put right, and in bushfire areas they may do the work themselves and recover the cost.

Can you run power to a shed, studio or stables?

Yes, and on acreage it is one of the most common jobs we do. The distance is what makes it interesting. A long run has to be sized for voltage drop rather than just for current, because a cable that is fine on load calculations can arrive at the shed with too little voltage left to run a compressor or a pump properly. It also needs its own protection, correct earthing at the far end and the right depth and mechanical protection if it is going underground. We work out the cable size from the actual distance and the actual load, not from what fitted last time.

Is bushfire risk something an electrician deals with?

In the rural north of the Shire, yes. Properties around Glenorie, Maroota, Wisemans Ferry, Annangrove and Kenthurst back onto bush, and where land is mapped as bush fire prone, new work and substantial alterations bring AS 3959 and Planning for Bush Fire Protection into the design with requirements flowing from the Bush Fire Attack Level. Beyond the paperwork, there is the practical side: keeping your own poles and lines clear of vegetation, and thinking about what happens to a house on tank water with an electric pump when the power goes off on a bad day.

Our estate is only a few years old. Surely there is nothing to fix?

New does not mean generous. A newer house is usually well built and correctly certified, and it is also usually specified to the load it had on the day it was finished. Then a pool goes in, the garage gets a car charger, someone adds a second air conditioner and the study becomes an office. The house is fine. The supply and the switchboard were sized for a different household. The good news is that this is much cheaper to fix on a modern installation than on a 1980s one, because the board is usually already sensible and there is normally room to grow into.

How does your pricing work?

Attending your job is a chargeable callout. We confirm what it costs when you book, and the price for the work itself is agreed before we start, so there are no surprises on the invoice.
