Switchboard Upgrades & Safety Switch Installation
Old fuse boxes, ceramic fuses, and boards without safety switches are one of the most common jobs we do — brought up to current standards so the rest of the house is actually protected.
Time for a switchboard upgrade?
If your board looks like any of these, it's worth getting checked.
- Ceramic fuses instead of circuit breakers
- No safety switches (RCDs) fitted at all
- Nuisance tripping every time you run a few appliances
- Buying or selling — a pre-purchase electrical inspection flags this fast
- Adding solar, an EV charger, or a big new appliance
- The board is visibly old, rusted, or overcrowded with add-on wiring
Why it matters
Safety switches save lives
A modern board with RCDs cuts power fast enough to prevent a fatal shock — old fuse boards often have none fitted.
Fire risk reduction
Ceramic fuses and overloaded old boards are a known fire risk under sustained modern loads.
Insurance & sale readiness
Many insurers and buyers now expect a compliant board — this removes it as a sticking point.
Room to grow
A properly sized board leaves headroom for solar, EV charging, or future renovations.
What a switchboard upgrade includes
Every upgrade is scoped to the property — typically covering:
- Removal of old fuses & obsolete wiring
- New circuit breakers
- Safety switches (RCDs) on all circuits
- Surge protection where appropriate
- Correctly labelled circuits
- Compliance certificate on completion
- Load capacity review for future additions
- Metering & supply authority liaison if required
Flagged during a pre-purchase inspection, sorted before settlement
A buyer's pre-purchase electrical inspection turned up a rusted ceramic-fuse board with no safety switches at all — a common find in older Southern Highlands homes, and exactly the kind of thing that spooks a buyer or an insurer. With settlement on a deadline, we assessed the board, quoted it on the spot, and had a fully compliant switchboard with RCDs on every circuit installed and certified before the sale went through.
One less thing standing between them and settlement day — and a board with the headroom to add solar or an EV charger down the track.
Book a switchboard inspection
We'll assess the board on site, explain exactly what needs doing and why, and quote it before any work starts.
Frequently asked questions
How do I know if my switchboard needs upgrading?
Warning signs include an old ceramic fuse board, no safety switches (RCDs), frequent tripping, or a board that can't handle modern appliance loads.
Is a safety switch (RCD) compulsory in NSW homes?
NSW regulations require safety switches on power and lighting circuits in most homes — we can check your board's compliance and upgrade it to current AS/NZS 3000 standard.
Do you upgrade switchboards in older Southern Highlands homes?
Yes — switchboard upgrades in older homes across Wilton, the Southern Highlands and Wollondilly are one of our most common jobs.
