Ceramic fuses
Rewireable fuses are still found in some Miranda homes and offer less protection than circuit breakers.
Switchboard Upgrades
Switchboard upgrade in Miranda
A switchboard upgrade replaces an ageing board with modern circuit breakers and safety switches. In Miranda, many post-war and 1960s brick homes still run on boards installed when households used far less electricity.

01 / Signs You Need This
When to arrange switchboard upgrade.
A switchboard can work for years without obvious trouble, then show its age once more load is added.
Missing safety switches
Some circuits, often lighting or older power circuits, may have no safety switch protection at all.
Frequent tripping
Breakers that trip under normal use can point to overload or a board that no longer suits the home.
No room for new circuits
A full board makes it difficult to add air conditioning, an EV charger or a new kitchen.
02 / What's Included
A considered scope, based on the property.
A switchboard upgrade covers the board itself and the checks that make it safe to connect.
New enclosure and circuit breakers
Individually protected circuits, clearly labelled.
Safety switch protection
Safety switches arranged across the home's circuits to current requirements.
Circuit testing
Each circuit tested as it is reconnected, so existing faults are identified.
Allowance for future loads
Space planned for what you intend to add.
03 / How the Job Works
From the first conversation to certification.
Most upgrades follow the same four stages.
Enquiry and site assessment
You tell us what is happening or what you want added. We look at the switchboard, the circuits involved and the property before recommending anything.
Written quote
You receive a written quote describing the board, the protection and any wiring issues found.
Installation or repair
The power is isolated, the old board removed and the new board installed and connected.
Testing and certification
The work is tested before we leave, and a Certificate of Compliance for Electrical Work (CCEW) is issued where the work requires one.
04 / Safety & Compliance
Electrical work completed properly in NSW.
In NSW, switchboard work must be carried out by a licensed electrician and tested to the Australian wiring rules (AS/NZS 3000).
Where the work requires it, we lodge a Certificate of Compliance for Electrical Work (CCEW), which records what was done and confirms it has been tested.
05 / Exclusions & Limitations
What the service does not automatically include.
Some related work sits outside a standard board upgrade.
Network-side work
Changes to the service mains or meter are coordinated with our accredited Level 2 partners.
Faulty existing wiring
Faults found during testing are explained and quoted separately.
06 / Local Knowledge
Sutherland Shire and St George homes are not all wired alike.
Miranda's residential streets around Westfield and the station include original brick homes, renovated houses and villa developments. Each has a different board arrangement, so we assess on site.
Units and villas may have boards in a shared meter room, which affects access and planning.

Switchboard upgrade questions, answered.
How do I know if my Miranda home needs a switchboard upgrade?
Ceramic fuses, missing safety switches, regular tripping or no space for new circuits are the common signs.
Will the power be off during the upgrade?
Yes, for part of the day while the board is replaced. We explain the timing before we start.
Do villas and units need a different approach?
Often the board or meter is in a shared area, so we plan access with the owner or strata manager.
Can a new board be sized for an EV charger later?
Yes. We can allow space for future circuits.
Is a CCEW provided?
Yes, where the work requires one.
