Your switchboard acts as the central control point for your home’s electrical system. It distributes electricity throughout the property and contains protective devices that shut off the power when an electrical fault occurs.
However, many older switchboards were designed when homes used far fewer electrical appliances. Modern equipment such as air conditioners, induction cooktops, solar systems, pool pumps, battery systems and electric vehicle chargers can place much greater demand on an ageing electrical installation.
For this reason, it is important to recognise the warning signs that your switchboard may need an inspection or upgrade.
1. Your switchboard still has ceramic fuses
Many older Perth homes still contain ceramic rewireable fuses.
Although these fuses may continue to operate, they do not provide the same convenience or level of protection as modern circuit breakers and safety switches.
In addition, replacing fuse wire can be inconvenient and may make it harder to identify the circuit causing the problem.
A modern switchboard helps an electrician identify faults more easily and allows you to reset a circuit safely after the electrician has confirmed that no dangerous fault remains.
2. Your safety switches are missing or outdated
Safety switches, also known as residual current devices or RCDs, quickly disconnect the electricity supply when they detect current leaking to earth.
Circuit breakers and RCDs perform different functions.
A circuit breaker primarily protects electrical wiring against overloads and short circuits. In comparison, an RCD provides additional protection against electric shock.
An electrician can inspect your switchboard, confirm which circuits have RCD protection and test whether the safety switches operate correctly.
3. Your power keeps tripping
A faulty appliance can occasionally cause a circuit breaker or safety switch to trip.
However, repeated tripping may indicate a more serious problem, including:
- An overloaded circuit
- Damaged electrical wiring
- Moisture entering electrical equipment
- A faulty appliance
- A deteriorating safety switch
- A fault elsewhere in the electrical installation
Avoid repeatedly resetting a tripped switch without identifying the cause.
Instead, unplug any recently connected appliance and contact a licensed electrician if the circuit continues to trip. An electrician can test the circuit and locate the cause of the fault.
4. You notice heat, buzzing or a burning smell
A switchboard should not produce unusual heat, buzzing, crackling sounds or a burning smell.
These warning signs may indicate loose electrical connections, damaged equipment or overheating components.
Therefore, you should treat any of these symptoms seriously.
Turn off the electricity at the main switch when it is safe to do so and contact a licensed electrician promptly.
Do not remove the switchboard cover or attempt to repair the switchboard yourself.
5. You are installing a major new appliance
Before installing a large new appliance, ask an electrician to assess your switchboard and electrical supply.
For example, an assessment may be necessary before installing:
- An induction cooktop
- A large air-conditioning system
- A pool or spa
- An electric oven
- A solar or battery system
- An electric vehicle charger
- Workshop machinery
The electrician will check the available electrical capacity, existing circuit protection and switchboard space.
They will also determine whether the new appliance needs a dedicated circuit or additional switchboard work.
6. There is no room for additional circuits
An overcrowded switchboard can make electrical upgrades and future maintenance more difficult.
For instance, there may be no space available for another circuit breaker when you install a new air conditioner, cooktop, EV charger or outdoor circuit.
As a result, the electrician may need to install a larger switchboard enclosure or upgrade the entire switchboard.
Planning ahead can help you prepare your home for future renovations, solar panels, battery storage and electric vehicles.
7. The switchboard is damaged or poorly labelled
Finally, inspect the outside of your switchboard for visible signs of damage.
Ask an electrician to investigate problems such as:
- Missing covers
- Exposed openings
- Rust or corrosion
- Water damage
- Cracked components
- Loose equipment
- Missing or unclear circuit labels
Clear circuit labels make it easier to identify and isolate a particular area of the home during maintenance or an emergency.
In addition, a properly organised switchboard allows an electrician to complete testing and fault finding more efficiently.
What happens during a switchboard upgrade?
The work required will depend on the age, condition and design of your existing electrical installation.
However, a typical switchboard upgrade may include:
- Inspecting the existing switchboard and electrical installation
- Removing outdated ceramic fuses or protective devices
- Installing modern circuit breakers and RCD protection
- Replacing or upgrading the switchboard enclosure
- Adding or separating circuits where required
- Organising and clearly labelling each circuit
- Testing the completed installation
The electrician should explain the proposed work before starting and advise you if testing reveals any additional faults.
Benefits of upgrading your switchboard
A modern switchboard can provide several benefits for your property.
These may include:
- Improved electrical safety
- Better circuit protection
- Easier fault identification
- Space for additional electrical circuits
- Improved compatibility with modern appliances
- Better preparation for solar, batteries and EV charging
- Clearer circuit identification
Most importantly, a switchboard upgrade can help ensure that your electrical system is suitable for the way your household uses electricity today.
