Old switchboards can put your family at risk. They may overheat, trip breakers, or even start a fire. Here’s a clear look at what a switchboard upgrade means, why you might need one, and how the work gets done.
What Is a Switchboard and Why Upgrade?
A switchboard is the central hub that distributes electricity from the mains to every circuit in your home. It houses the main switch, circuit breakers or fuses, and safety devices like RCDs. Modern boards use insulated breakers that cut power quickly if a fault occurs, which is far safer than the old ceramic fuses many older homes still have.
Upgrading replaces those outdated components with compliant, insulated breakers and adds RCD protection where required. The new board can handle higher loads, making space for air‑conditioners, solar inverters, or an electric car charger. It also brings the installation up to the current Australian Wiring Rules (AS/NZS 3000) and local council requirements.
Homeowners who add new appliances often find their old board can’t keep up. A newer board spreads the load more evenly, reducing the chance of frequent trips. It also lowers fire risk because modern breakers don’t melt like old ceramic fuses.
Faze Electrical’s electricians assess your existing board, recommend the right size and type, and install it to meet safety standards. Their experience with residential and commercial projects means they know how to fit a new board into tight spaces without major renovations.
For a deeper technical definition, see Wikipedia’s entry on electric switchboards, which explains the components and how they protect a home’s wiring.
Safety Risks and Warning Signs
Old switchboards pose several hazards. Ceramic fuses can overheat and melt, creating a fire‑prone situation. Without RCDs, a fault may give you an electric shock before the breaker trips. Loose connections can spark, damaging outlets or appliances.
Watch for these warning signs: flickering lights, frequent breaker trips, a burning smell near the board, or visible corrosion on terminals. If you notice any of these, it’s time to call a licensed electrician.
In Queensland, the WorkSafe authority requires that any switchboard with illegal fuses be replaced to meet safety standards. Non‑compliant boards can also affect your home insurance, as insurers may refuse claims if the cause is an outdated electrical system.
Faze Electrical regularly conducts safety audits and can spot problems before they become dangerous. Their team follows the latest safety protocols and uses insulated tools to avoid accidental shocks during inspection.
The Switchboard Upgrade Process Step‑by‑Step
The upgrade starts with a site inspection. The electrician checks the existing board, measures the incoming supply, and notes any asbestos‑containing panels that need special handling.
Next, they shut off power at the meter and verify it’s dead with a tester. This protects you and the crew while they remove the old board.
They then fit a new enclosure that matches the space. If the old board was three‑phase, they ensure the new one can handle the same load and keep the phase sequence correct , a mistake here can damage appliances.
New circuit breakers and RCDs are installed according to the load calculations. Each circuit gets a label that matches the rooms or appliances it serves. The electrician connects the earth and neutral bars, tightens all connections, and applies fire‑resistant sealant where required.
Finally, they perform compliance testing. This includes RCD trip time testing, continuity checks, and a visual inspection. Once everything passes, they hand you a certificate of compliance.

FAQ
Do I need a permit for a switchboard upgrade?
Yes, most Australian states require a permit before any electrical work that involves the main supply. The permit ensures the work meets the Wiring Rules and is inspected by a qualified authority.
How long does a typical upgrade take?
A standard residential upgrade usually takes one to two days, depending on the size of the board and whether any asbestos removal is needed.
Can I upgrade my switchboard myself?
No, Australian law mandates that only a licensed electrician may work on the main switchboard. Doing it yourself can void insurance and breach safety regulations.
Will an upgrade affect my electricity bill?
Directly, no , the upgrade doesn’t change how much power you use. However, a modern board can reduce waste from faulty connections, which may lower your bill slightly.
Is my home ready for solar or an EV charger after an upgrade?
Usually, yes. A new board can accommodate the extra load from a solar inverter or a dedicated EV charger circuit, provided the electrician sizes it correctly during the inspection.
How much does a switchboard upgrade cost in Australia?
Costs vary with the size and complexity of the job. For a typical single‑phase home, prices start around a few thousand dollars; see our switchboard upgrade cost guide for more detail, but you’ll get an exact quote after the initial assessment.
