Switchboard Upgrades & Fuse Box Replacement
If your board still has ceramic fuses, no RCDs, or circuits labelled in someone's handwriting from 1983 — it's time. I upgrade boards to current WA standards so your home is safe, your insurance is valid, and your modern kit doesn't trip every time you put the kettle on.
Why switchboard work is the biggest job on this side of town
Midland, Midvale, Bellevue, Greenmount, Swan View — a huge chunk of the housing stock east of the river is 60s, 70s and 80s brick veneer. Most of those boards were built for an era when a house had a fridge, a TV, a hot water system and maybe an electric stove. Not a modern household with an induction cooktop, two split systems, a ducted reverse-cycle, a pool pump, EV charging, and solar feeding back in.
You know you need an upgrade when:
- Half your switchboard is ceramic fuses with bits of fuse wire
- There are no RCDs, or only one RCD on a single circuit
- Your main switch has tripped three times this year and a sparkie told you "you need a bigger board"
- You can smell warm plastic when the electric oven's been running for an hour
- Circuits are unlabelled or labelled wrong
- You've added solar, an EV charger, a new kitchen, or a split system and it's been "worked in" to an already-full board
- You're selling or leasing the property and the inspector has flagged RCD non-compliance
- The board is outdoors, unweatherproofed, and hasn't been touched since the house was built
What a proper upgrade looks like
I don't "patch" old boards. When the whole board needs replacing, the whole board gets replaced. When it's one RCD swap on a compliant modern board, that's what you pay for.
A full upgrade typically includes:
New enclosure
Weatherproofed properly if external, correctly sized for the circuit count plus future growth
Two RCDs minimum
To current WA standard (most homes end up with three or four for proper circuit separation)
Main switch and incomer
Checked, replaced if marginal
Circuit protection
Modern MCBs, correctly sized for the cable and the load
Neutral bar and earth bar
Properly terminated, no doubled-up neutrals
Every circuit labelled
In printed labels, not pencil
Meter box tidied
Old tape, disconnected cables, cobwebs and ancient wasp nests gone
Test and tag
On the finished board — insulation resistance, loop impedance, RCD trip time on every circuit
Certificate of Compliance
The paperwork for your insurer, your conveyancer, or your bank
How long it takes
- Straightforward domestic changeover: usually a one-day job, power off mid-morning, back on by mid-afternoon
- Hills acreage with sub-boards: 1-2 days depending on the sub-board work
- Swan Valley cellar door or winery with three-phase: site visit needed before anyone quotes a timeline
WA RCD and smoke alarm rules — what you actually need to know
WA law has required a minimum of two RCDs on every residential property sold or leased since 2009. Every property transfer is a compliance check. If you're selling or leasing and the inspector flags it, you'll need certified RCDs installed and a Certificate of Compliance before settlement or the tenancy signs.
Same applies to hardwired interconnected smoke alarms — mandatory on property transfer since 2009, on all rentals since 2014, and every alarm has a 10-year life from the date printed on the casing.
I sort both at the same time when you book a switchboard upgrade. One site visit, one invoice, all the paperwork your conveyancer needs.
Special cases east of the river
Three-phase supply
More common on this side of town than any other Perth metro fleet. Swan Valley wineries, Helena Valley acreage, hills properties with workshops. Three-phase upgrades are different work to single-phase and need to be quoted on site.
Solar-driven upgrades
A lot of 2014-2018 hills and Swan Valley solar installs are now out of warranty and the retailer's closed. If your system's under-performing or the inverter's tripping, it's often a board issue, not a panel issue. Happy to take a look before you spend money replacing panels unnecessarily.
EV charger installs
Most Midland and hills homes need a board review before a wall-mounted EV charger goes in. A 32A or 40A dedicated circuit for a Tesla wall connector will trip the main switch on an older board if the existing load is already close to capacity.
Generator changeover panels
Hills properties with standby generators need a proper interlocked changeover panel so you don't back-feed the grid during a bushfire-season outage. It's not optional and it's not safe to DIY.
What it costs
Straight answer: it depends on what's there and what's needed. A 4-circuit RCD retrofit on a compliant modern board is not the same job as a full ceramic-fuse board replacement with smoke alarms and a meter box tidy.
