Strata Main Switchboard and Consumer Mains Sydney
Upgrading and maintaining the main switchboard and consumer mains that serve every lot in your strata scheme — common property work done right, compliant and documented.
In a strata building, the main switchboard and the consumer mains running to each lot's meter are common property, which makes them the owners corporation's responsibility to maintain.
High Demand Electrical carries out condition assessments, upgrades and defect rectification on strata main switchboards and consumer mains across Sydney, working with strata managers, building managers and owners corporations to keep the building compliant without disrupting residents any more than it has to.

AS/NZS 3000 and the Owners Corporation’s Maintenance Duty
All switchboard and consumer mains work is carried out to AS/NZS 3000, the wiring rules that set the standard for cable sizing, protection and switchboard construction in NSW. Separately, the Strata Schemes Management Act 2015 places a duty on the owners corporation to properly maintain common property, which is the legal basis for budgeting and approving this kind of work rather than leaving it until a defect notice or an insurance claim forces the issue.
If a defect notice has already been issued against the building's main switchboard or consumer mains, our defect notice rectification page covers how that process is cleared.

Why Strata Switchboards and Consumer Mains Need Attention
Many Sydney strata buildings are running switchboards and consumer mains that were never designed for the loads a modern building actually places on them.
1
Ageing switchboard gear
Older boards can have deteriorated components, undersized protection or fittings that no longer meet current standards.
2
Rising per-lot demand
EV chargers, air conditioning and modern appliances push consumer mains sized decades ago well past comfortable capacity.
3
Corroded consumer mains
Mains run through risers and subfloors for decades can corrode or degrade well before it's obvious from outside.
4
Insurance & compliance pressure
Building insurers and strata inspection reports increasingly flag ageing switchboards as a risk item.
None of this means a scheme has done anything wrong — most buildings simply haven't needed this work until now. A proper condition assessment is what turns "the report flagged it" into an actual scope and price the OC can act on.

How High Demand Electrical Assesses and Upgrades Strata Boards
Condition Assessment
A physical inspection of the main switchboard and accessible consumer mains, including thermal imaging where useful, to identify actual defects rather than guess from age alone.
Scope & Quote for OC Approval
A written report and fixed-price quote your strata manager or committee can table and approve, setting out exactly what needs doing and why.
Staged Works Around Residents
Where possible, consumer mains are transferred lot by lot or in small groups so the whole building isn't without power for the length of the job.
Testing & Certification
Full testing once the work is complete, with a Certificate of Compliance for Electrical Work and documentation the OC can keep on file.

Common Property vs Your Lot: Where the Boundary Sits
Common Property
Owners Corporation
The main switchboard and the consumer mains up to and including each lot's meter.
- Main switchboard & incoming supply
- Riser and subfloor consumer mains
- Common area lighting & circuits
Lot Owner
Inside the Lot
Generally from the meter or the lot's own switchboard inward.
- The lot's individual switchboard
- Wiring, outlets and fittings inside the lot
- Any equipment the lot owner has installed
This split can be varied by a scheme's registered by-laws, so it's always worth checking the specific by-laws for your building rather than assuming the general rule applies exactly as written. We can point to the relevant clause during a condition assessment if it's unclear.

Frequently Asked Questions
FAQs
Who is responsible for the main switchboard in a strata building?
The main switchboard and the consumer mains that run from it are common property, so under the Strata Schemes Management Act the owners corporation is responsible for maintaining and repairing them, not individual lot owners.
Where does common property electrical end and my lot begin?
As a general rule, the main switchboard and consumer mains up to and including each lot's meter are common property. From the meter or the lot's own switchboard inward is generally the lot owner's responsibility, though this can be varied by a scheme's registered by-laws.
Does an old strata switchboard need to be replaced, or just repaired?
It depends on the condition. A condition assessment will identify whether individual defects can be rectified or whether the board has reached the point where a full replacement is the safer, more cost-effective option long-term.
Can strata switchboard work be staged to avoid a full power outage?
In most buildings, yes. Consumer mains can usually be transferred lot by lot or in small groups, so the whole building isn't without power for the length of the job.
How much does a strata main switchboard upgrade cost?
Cost depends on the number of lots, the switchboard's current condition, and whether consumer mains need replacing as well. Every strata quote follows a proper condition assessment rather than a phone estimate.
