Switchboard Upgrades in Berowra
Ceramic fuses or breakers that trip without warning point to the same problem: a tired board.
It's one of the most common jobs on our books in Berowra.

Inside a Typical Switchboard Upgrades Job
Swapping a tired board for a modern one is a bigger job than it looks from the outside. This is what a full upgrade generally involves.
Board replacement. The old enclosure, ceramic fuses included, comes out and a new one goes in.
RCBOs and safety switches. Combined breaker-and-safety-switch units protect each circuit on its own, instead of one shared switch covering the whole house.
Circuit labelling. Clear labels so the next person to open the board, tradesperson or otherwise, knows exactly what feeds what.
Fuse-to-breaker conversion. Out go the ceramic fuses, in come breakers you reset with a flick instead of a run to the hardware shop.
Rectification as we go. Anything non-compliant behind the old board, from unearthed circuits to degraded cable, gets picked up and dealt with on the day.
There's no guessing once we lift the old cover away. A board that's ticked over quietly for decades still has to be opened up properly to reveal what's really behind it.
How to Tell You Need Switchboard Upgrades
A board can run for years past its use-by date before it actually fails. Watch for these instead of waiting for that:
- Ceramic fuses rather than modern circuit breakers
- No safety switch listed anywhere on the board, or just one covering everything
- Breakers tripping regularly, especially with more than one appliance running
- Scorch marks, a burning smell, or warmth around the board itself
- A renovation on the way that will need extra circuits
- A faint buzz or hum coming from the board when things are quiet
A breaker that keeps resetting, or a burnt smell drifting off the board, both trace straight back here.
What Affects the Cost of Switchboard Upgrades
The written quote is fixed once agreed, but a few things shape what that number ends up being.
- How many circuits the new board needs to carry
- Access to where the board is mounted
- The condition of the cable feeding into it
- Whether it's a straightforward fuse-to-breaker swap or a full enclosure replacement
- Any defects found once the old board comes off the wall
We look at the board in person before pricing anything, so the quote reflects the actual job, not a guess.
A board that's already been partly modernised, with a mix of old fuses and newer breakers, often costs less than a full original setup, since some of the groundwork is already done.
Why Berowra Properties Call For This
Original boards are still common on the ridge streets around The Gully Road, where houses have stood since the suburb's 1960s and 1970s expansion. Ceramic fuses were standard then, and plenty never got upgraded when circuit breakers took over.
Add a reverse-cycle unit or an EV charger to the mix and a household is drawing well past what that board was designed to carry.
Owners here tend to notice the pattern the same way: fuses blowing more often each year, or a board that turns out to have no safety switch at all once someone finally checks.
It's rarely one dramatic failure. Usually it's a slow build of small warning signs that finally tip someone into making the call.
Standards and Paperwork, Explained Simply
A switchboard upgrade sits under AS/NZS 3000, the national wiring standard that governs how circuits are built and protected. The modern baseline is an RCD guarding each circuit, not a single one covering the whole house.
Since the job is notifiable, the paperwork gets lodged with the regulator once testing wraps up and the certificate reaches you. Keep it filed; it matters for insurance and for a future sale.
Insurers increasingly ask about board age and safety switches when a claim is lodged. An upgrade with proper paperwork answers that question before it's even raised.
This isn't work to attempt yourself. Switchboards carry live, high-current circuits, and DIY electrical work is illegal in NSW for good reason.
How it works
The Process, and What It Typically Takes
On-Site Look
We check the existing board, note what's original and what's been added since, and talk through what's actually needed.
Written Quote
The number goes on paper before anything gets touched, so there's nothing to negotiate once work starts.
Board Swapped Over
Power is turned off at the point of supply while the new enclosure is fitted and every circuit reconnected in turn.
Signed Off
We hand over the compliance paperwork and walk you through the new labelling before we leave.
A standard swap is usually wrapped inside a single visit. Anything more involved, like a board with tangled or undocumented wiring behind it, gets flagged at quote stage rather than discovered halfway through.
Why This Is a Job for Our Team
Of everywhere in a house, the switchboard is where a cut corner turns genuinely dangerous, so the standard holds no matter the job size.
If our work is the cause of a fault years down the track, we come back and fix it, no labour charge either way.
That cover matters more here than on most jobs. A board sits shut behind its cover for years at a stretch, so what's done inside it on day one is what you're living with long after.
Servicing Nearby Homes Too
We fit switchboards across Berowra and out into Mount Colah, Hornsby, Asquith and Normanhurst.
A board upgrade often uncovers the case for house rewiring, and it clears the way for extra outlets once the old capacity limit is gone. See power points for that side of things.

Common questions
Your Switchboard Upgrades FAQs
Is a permit or notification needed for switchboard upgrades in NSW?
Yes, upgrading a board counts as notifiable work, so a Certificate of Compliance follows once testing wraps up.
What are the signs I need a switchboard upgrade?
A board still running ceramic fuses, breakers that keep tripping, no RCD anywhere in sight, or a renovation on the horizon that will outgrow what's currently installed.
How long does a switchboard upgrade take?
Most domestic jobs are finished within the one visit. Where the wiring behind the board is tangled or undocumented, that gets flagged when we quote, before any work starts.
What warranty comes with a switchboard upgrade?
Labour is guaranteed for life, and the board and breakers themselves carry twelve months of cover on top of what the manufacturer already offers.
Do you handle strata or apartment switchboard upgrades in Berowra?
Houses dominate here, but board work for a small strata title or unit block does come up, and we work directly with owners corporations when it does.
Do you supply the materials or can I buy my own?
Boards and breakers come included in the job, chosen for reliability rather than whatever happens to be cheapest that week.
