If you have a shed situated on acreage and you're tired of managing extension leads from your house, it’s high time to have it properly wired. Whether you own a simple storage shed that requires a light and a power point, or a comprehensive workshop equipped with welders and compressors, there's a correct procedure to follow. In NSW, the only legal approach to achieve this is through a licensed electrician.
This guide outlines the steps involved in supplying power to your shed, detailing what your electrician will need to install, and providing an estimate of the likely costs on the Mid North Coast.
Understanding Your Shed's Power Supply: The Importance of Cable Run
The primary consideration in any shed wiring task is effectively transferring power from your main switchboard to the shed. On larger properties, this distance can extend to 30, 50, or even over 100 metres. The greater the distance, the larger the cable diameter required to manage voltage drop.
When it comes to cable runs, you have two viable options:
- Underground cable run — This is the most prevalent and aesthetically pleasing choice. Your electrician will lay heavy-duty cable through orange conduit buried at least 500mm deep, or deeper if heavy vehicles traverse the area. This method protects the cable from weather damage, animals, and falling branches, making it the preferred option for most acreage properties.
- Overhead cable run — While less common, this option may be necessary if the ground is solid rock or the terrain complicates trenching. Overhead runs require adherence to proper clearance heights and support poles, which can increase costs.
For the majority of properties in and around Bellingen, Coffs Harbour, and the Mid North Coast, an underground cable run is the recommended method. Your electrician in Bellingen can evaluate your site and suggest the optimal route for the installation.
Establishing Your Shed's Power Supply: The Necessity of a Dedicated Sub-Board
It’s inadequate to merely run a single cable to the shed and plug in appliances. Any shed receiving a proper power supply necessitates a dedicated sub-board, often referred to as a distribution board. This functions as a mini switchboard located within the shed to manage all circuits effectively.
Your sub-board will typically include the following:
- Main switch — This enables you to isolate all power to the shed independently from the main house.
- RCDs (safety switches) — These devices are mandated by NSW electrical regulations. They provide rapid power cut-off in milliseconds in the event of a fault, which is crucial for safety in a shed environment where moisture, dust, and damaged leads are prevalent.
- Circuit breakers — These offer individual protection for each circuit within the shed, including lighting, general power, and dedicated tool circuits.
If your house's switchboard is older, your electrician might also recommend upgrading the main board to accommodate the extra load heading to the shed.
What Essential Features Should Be Installed Inside Your Shed?
The specific installations your electrician makes inside the shed will depend entirely on its intended use. Here’s a breakdown of common setups.
Creating an Efficient Basic Storage Shed
If your shed is primarily for storing tools, a ride-on mower, or assorted gear, consider this setup:
- LED batten lights — One or two ceiling-mounted LED batten lights will adequately illuminate the entire space. Your electrician can provide advice on the optimal lighting arrangement based on the shed's dimensions.
- Two to four general power points — These will be sufficient for plugging in a charger, a radio, or a drop saw when needed. Expect standard power points and switches on a single circuit.
- External light — A weatherproof LED light above the door ensures visibility, preventing you from fumbling in the dark.
Setting Up a Fully Equipped Powered Workshop Shed
If you regularly utilise power tools such as drop saws, bench grinders, and dust extractors, you'll require a more advanced wiring setup:
- Multiple circuits — Separate circuits for lighting, general power, and dedicated tool outlets help to avoid flickering lights whenever a tool is activated.
- Higher-rated power points — Providing 15-amp or 20-amp outlets is essential for accommodating heavier tools.
- Additional power points, strategically placed — Install points at bench height rather than merely at skirting level. Consider the actual locations of your workbenches.
- Dedicated lighting — Ensure brighter, more focused lighting is installed over work areas, perhaps utilising LED high-bays for larger sheds.
For comprehensive guidance on configuring dedicated circuits for heavy tools, refer to our article, Powering a Rural Workshop — Dedicated Circuits for Heavy Tools and Equipment.
Establishing a Comprehensive Workshop With Three-Phase Power
If you plan to run heavy-duty machinery, such as large compressors, lathes, MIG welders, or commercial-grade equipment, single-phase power may not suffice. In this case, you should consider three-phase power.
Three-phase power provides more consistent and higher-capacity energy. Your electrician will need to:
- Arrange for a three-phase supply from your energy distributor, which can take several weeks on the Mid North Coast.
- Install a three-phase sub-board in the shed, complete with appropriate breakers and RCDs.
- Run heavier cabling — be advised that three-phase cable runs tend to be more expensive, especially over extended distances.
- Install three-phase outlets — These industrial-style sockets must be rated for the equipment being operated.
If you are unsure whether three-phase power is necessary for your needs, read our article, Do I Need Three-Phase Power on My Property? This resource explains when it's beneficial and when a well-designed single-phase setup will suffice. We also offer complete three-phase switchboard installations should you choose that route.
The Importance of Surge Protection for Your Shed
Properties on acreage in the Mid North Coast often face intense lightning storms. A direct or nearby strike can wreak havoc on everything within your shed, damaging tools, chargers, fridges, and any equipment connected to power.
Installing a quality surge protection device within the sub-board serves as affordable insurance. This device absorbs voltage spikes before they can reach your valuable equipment. For sheds housing expensive tools or a workshop setup, surge protection is an absolute necessity.
If your property utilises a generator for backup power, your electrician can also install a generator changeover switch, allowing the shed (and the house) to transition to generator power safely during outages.
What Regulations Surround Council Approval and Compliance?
There are several important regulations to consider:
- All electrical work in NSW must be performed by a licensed electrician. There are no exceptions to this rule. While you can dig the trench yourself to save on labour costs, all electrical work—cabling, connections, sub-board installation, and everything else—must be completed by a licensed contractor who will issue a Certificate of Compliance (CCEW).
- Depth requirements for underground cables must comply with AS/NZS 3000 (the Wiring Rules). Your electrician will manage this aspect of the installation.
- If the shed is a new construction, development approval may be necessary depending on your council and the shed's dimensions. While the electrical work itself does not require a separate permit, the overall building project might.

Estimating the Costs of Shed Wiring on Acreage
Each shed presents its own unique challenges—distance from the house, whether you need single-phase or three-phase, the number of circuits required, and soil conditions for trenching all factor into the costs. Here’s an approximate guide for the Mid North Coast:
- Basic shed wiring (light + a few power points, short cable run) — Starting from $2,500
- Powered workshop shed with sub-board and multiple circuits — Starting from $4,500
- Full workshop setup with three-phase, dedicated circuits, and surge protection — Starting from $8,000+
Longer cable runs (50m+), rocky terrain necessitating a rock saw, or three-phase supply upgrades will all increase the overall cost. The most reliable way to receive an accurate estimate is to have your electrician conduct a site visit, assess the cable route, and understand the intended use of the shed.

Addressing Your Frequently Asked Questions
Can I Wire My Shed Myself In NSW?
No, all electrical work in NSW must be conducted by a licensed electrician. This encompasses running cables to the shed, installing the sub-board, power points, lighting, and everything else. Engaging in DIY electrical work is both illegal and hazardous. Your electrician will provide a Certificate of Compliance upon completion of the work.
How Deep Does Underground Cable Need To Be Buried?
According to the Australian Wiring Rules (AS/NZS 3000), underground cables within conduit must be buried at a minimum of 500mm deep under standard conditions. If vehicles are likely to drive over the run, the depth must be increased typically to 600mm or more. Your electrician will determine the correct depth for your property.
Do I Need A Separate Meter For My Shed?
In most instances, no. Your shed's sub-board connects back to your main house switchboard and draws power from the same meter. A separate meter is only necessary if the shed is utilised as a separate dwelling or commercial premises, which involves a different discussion with your council and energy distributor.
How Long Does It Take To Wire A Shed On Acreage?
A standard shed wiring project—encompassing trenching, cable installation, sub-board setup, lights, and power points—typically requires one to two days to complete once the trench is prepared. If you're digging the trench yourself, your electrician can provide you with the precise route and depth prior to commencing. Three-phase installations usually take longer as the supply connection must first be arranged with the distributor.
Can I Run Power From The Shed To Other Buildings?
Yes, it is possible, but each additional building will require its own appropriately rated cable run and may need its own sub-board depending on the electrical load. Your electrician can plan the entire layout across multiple buildings, ensuring that the cabling and switchboard capacity are adequate from the outset, rather than making subsequent additions that could lead to complications.
