The most common hazard we find in Mountains homes
Ceramic fuses, no safety switches, and a board that hasn't been touched since the house was wired. It's the single most common thing we see up here, and it's the one that matters most — a modern board detects a fault in milliseconds and cuts the power before it becomes a fire or a shock. Older homes are also running far more than they were ever wired for, so we look at the supply feeding the board as well as the board itself.

What an upgrade involves
Ceramic fuse replacement
Rewirable fuses swapped for modern circuit breakers that trip reliably every time.
RCBO protection
Combined overload and earth-leakage protection on every circuit, not just a couple of them.
Consumer mains upgrade
Heavier mains from the point of attachment to the board where the existing ones can't carry the load.
Single to three phase
Applied for through Endeavour Energy, metering coordinated, and the board built to suit.
Surge protection
Whole-of-home surge diverters — worth having anywhere that gets the storms we do.
Board relocation
Boards moved out of wardrobes, roof spaces and other places they should never have been.
Labelling and schedule
Every circuit identified and a printed schedule left in the board. No more guessing.
Compliance certificate
Tested and issued with a Certificate of Compliance for Electrical Work.
How it works
A look at your board
On site, with the cover off. We can usually tell you straight away whether it needs attention.
A written quote
Fixed price for the board, the protection and the make-good, with options if there are any worth having.
Upgrade day
Most boards are a day with the power off for part of it. We'll tell you exactly how long before you book.
Labelled, tested, certified
Every circuit tested and labelled, schedule in the board, certificate issued.

How do I know if my switchboard needs upgrading?
If you have ceramic fuses with fuse wire, no safety switches, or a board that's full with no room to add a circuit, it needs attention. Book a free inspection and we'll tell you.
What's the difference between a safety switch and an RCBO?
A safety switch (RCD) protects against electric shock. A circuit breaker protects the wiring from overload. An RCBO does both, on an individual circuit — so a fault in one circuit doesn't take out the whole house.
How long does a switchboard upgrade take?
Most domestic boards are a single day, with the power off for part of it. We'll give you the timing before you book so you can plan around it.
Do I need to be home?
For a board upgrade, yes — we need access and you'll want to be there when the power goes off and comes back on.
Do I need a service upgrade as well as a new board?
Sometimes. If you're adding an EV charger, ducted air conditioning, an induction cooktop or a battery, the board itself might be fine but the mains feeding it may not be. We check both and tell you which one you actually need.
