Switchboard Upgrades That Actually Protect Your Home
A cheap fix on an ageing switchboard is a short-term patch on a long-term risk. Exell Electrical Services upgrades switchboards properly — right components, correct labelling, full compliance — so the job is done once and done right.
- Ceramic fuses replaced with modern safety switches (RCDs)
- Full compliance with AS/NZS 3000 wiring rules
- Capacity added for EV chargers, air conditioning & solar
- Switchboards inspected, tested & certified on completion
Why Your Old Switchboard Is the Weakest Link in Your Home
Many homes across Kirrawee, Sutherland and surrounding suburbs still run on switchboards installed in the 1970s or 1980s. These older boards rely on ceramic fuses — small porcelain and wire devices that were considered adequate when a typical household ran a fridge, a few lights and a TV. Today, that same board may be powering ducted air conditioning, multiple split systems, an induction cooktop, a home office and an EV charger. The mismatch between old capacity and modern demand is where faults, nuisance tripping and genuine fire risks begin.
Ceramic fuse wire can be replaced with wire of the wrong rating — intentionally or by a previous owner trying a DIY fix — and the board will simply carry more current than the wiring behind the walls was designed to handle. A modern switchboard replaces that guesswork with calibrated circuit breakers and residual current devices (RCDs) that trip within 30 milliseconds of detecting a fault. That response time is the difference between a tripped breaker and a cardiac event from electric shock.
An upgrade also means every circuit is individually labelled and load-balanced. Electricians in the Sutherland Shire regularly find homes where multiple high-draw circuits share a single breaker, or where the 'lights' breaker actually controls half the power points in the house — a common legacy of additions and renovations done without proper permits. Sorting that out during a switchboard upgrade gives you a board that reflects your home as it actually is.
NSW Fair Trading requires all switchboard work to be performed by a licensed electrician, and the completed installation must comply with AS/NZS 3000:2018 Wiring Rules. An electrician is also required to issue a Certificate of Compliance for Electrical Work (CCEW), which your insurer may request after a claim.
What a Switchboard Upgrade Actually Involves
A switchboard upgrade is not simply swapping one box for another. The process starts with a load assessment — measuring the total draw of your existing circuits and any planned additions like an EV charger or ducted air conditioning — so the new board is sized correctly from the start. Exell Electrical then sources a board enclosure and components rated for residential use: typically DIN-rail mounted circuit breakers and Type 1 or Type 2 RCDs (or combined RCBO units that provide both overcurrent and earth-leakage protection on a single circuit).
On installation day, the supply authority meter is isolated, existing wiring is terminated onto the new board, circuits are tested individually with a multifunction tester, and the board is fully labelled before power is restored. A CCEW is issued
- Load calculation before any components are ordered
- Individual RCD or RCBO protection on each circuit
- Multifunction tester used — insulation resistance, polarity, earth loop impedance
- Certificate of Compliance for Electrical Work (CCEW) issued
- Ausgrid/Endeavour Energy notification lodged where required
