Many issues can stem from an outdated switchboard, making switchboard maintenance crucial.

Increased Power Demand

The average modern household has a high demand for electrical power, thanks to our reliance on various electrical appliances and electrical equipment. Older switchboards were not designed to handle such a load, leading to potential hazards. Switchboard upgrades become necessary for safety and risk avoidance.

An upgraded switchboard with modular systems can accommodate evolving electrical demands, allowing additional modules to increase system capacity when needed. For homes experiencing significant increases in energy usage, an upgrade to the consumer mains might be necessary.

Outdated Technology

Old switchboards often lack modern safety features that significantly reduce the risks of electrical hazards. Some common safety risks associated with older switchboards include:

  • Exposed wiring
  • Porcelain fuses
  • Absence of safety switches
  • Asbestos panels

These safety risks can pose significant health and safety hazards. It is important to upgrade to a modern switchboard that meets current safety standards.

On the other hand, modern switchboards come equipped with circuit breakers, a safer alternative to traditional fuses. These breakers quickly disrupt power in overload conditions, significantly reducing the risk of electrical fires.

Compliance with Safety Standards

Ensuring compliance with current electrical safety standards is another compelling reason for a switchboard upgrade. Upgraded switchboards integrate devices like safety switches and residual current devices (RCDs), which are designed to meet safety regulations. This adherence to safety standards significantly reduces the risks of electric shocks and fires, providing a safer environment for occupants.

Remember, only licensed electricians should work on switchboards to ensure full compliance with electrical safety standards.


Switchboard upgrades are an essential part of modernizing any home, ensuring the safe and efficient handling of increased power demands. Understanding the need for such upgrades, the process involved, the types of modern switchboards, their essential components, and the costs and timeframe can help you make an informed decision. Remember, choosing a licensed and experienced electrician, and properly preparing your home for the upgrade is crucial for a smooth and successful upgrade process.


The Switchboard Upgrade Process

Now that we’ve highlighted the reasons for a switchboard upgrade let’s walk you through the process. Upgrading a switchboard is a three-step procedure that involves assessment, installation, and post-installation inspection. This process involves working with electrical wiring and integrating the new system into your home’s existing electrical infrastructure. Each of these steps is crucial and must be carried out by a qualified electrician to ensure safety and efficiency.


The first step in the switchboard upgrade process is a thorough assessment of your existing switchboard by a licensed electrician. This assessment involves evaluating the current electrical system, identifying necessary upgrades, and considering current and future electrical needs. The electrician will check for safety hazards, such as outdated wiring, assess its colour and appearance, and plan the upgrade of cables if needed to ensure ongoing electrical safety.

The assessment’s purpose is to determine the appropriate upgrade solution that aligns with the homeowner’s energy needs and safety requirements.


Once the assessment is done, the next step is the installation of the new switchboard. This process includes:

  1. Disconnecting the power supply to ensure safety
  2. Removing the old switchboard
  3. If your home has an asbestos panel in the switchboard, it must be removed by a certified electrician following safety regulations.

The new switchboard is then installed and connected to the home’s existing electrical system, which involves working with the home’s electrical wiring.

Post-Installation Inspection

Once the new switchboard is installed, a post-installation inspection is crucial. This inspection ensures the new switchboard’s proper function and compliance with safety standards. A thorough testing procedure is conducted, and documentation is provided to certify that the work adheres to the relevant standards.

The power supply remains disconnected until a licensed electrical inspector has conducted an inspection and verified that the work meets safety regulations.

Essential Components of an Upgraded Switchboard

Regardless of the type of switchboard you upgrade to, there are key components that your upgraded switchboard should include. These components, such as circuit breakers and residual current devices (RCDs), are necessary for optimal circuit protection.

Circuit Breakers

Circuit breakers are one of the key components of an upgraded switchboard. Modern circuit breakers come in single-pole and multi-pole versions, allowing them to protect either individual or multiple circuits respectively.

High-performance circuit breakers may include arc-fault circuit interrupters (AFCIs), offering enhanced protection against electrical fires originating from arc faults.

Safety Switches

Another key component of an upgraded switchboard is the safety switch. Safety switches can activate and turn off the power within 0.03 seconds upon detecting a fault, which is vital in preventing severe accidents and fatalities from electrocution.

Incorporating safety switches in switchboard upgrades is imperative to enhance the protection of families and employees from the risk of electrocution and fire hazards.

Residual Current Devices (RCDs)

Residual Current Devices (RCDs) should also be included in your upgraded switchboard. An RCD is a sensitive safety device that monitors the electric current and disconnects the circuit if it detects an imbalance, such as a leakage to earth.

By rapidly cutting off the electric current if a leakage is detected, RCDs play a crucial role in preventing serious electric shocks.

Costs and Timeframe for Switchboard Upgrades

Understanding the costs and timeframe involved is significant when considering a switchboard upgrade. The switchboard upgrade cost typically ranges between $900 and $1500, but this can vary based on several factors. The process’s duration can also vary depending on the chosen system type and extent of work required, such as additional wiring upgrades.

Cost Factors

Several factors can influence the cost of a switchboard upgrade. For instance, larger, higher capacity switchboards like a 250-amp board are costlier compared to standard 160-amp boards due to their increased size and capacity requirements.

The necessity for cabling and rewiring, as well as the condition of existing cables, can significantly increase the cost of a switchboard upgrade.


Depending on the specific circumstances and requirements of the installation, the average time taken for a switchboard replacement is usually three to five hours. However, this can vary based on the system type, with air-insulated substations requiring less erection time compared to indoor substations.

Longer power outages may occur in homes requiring a consumer main upgrade due to the connection between street wires and the building.

Selecting the Right Electrician for Your Switchboard Upgrade

Once you’ve decided to upgrade your switchboard and understood the costs and timeframe, choosing the right electrician for the job is the next step. Upgrading a switchboard is a complex task that should be handled by a qualified and licensed electrician to ensure safety and adherence to legal requirements.

Licensing and Experience

The electrician you choose should hold a valid electrical license, which ensures their qualification for electrical wiring work such as switchboard upgrades. Experience requirements for obtaining an electrical license typically include a specified period of employment in electrical wiring work, verified by referees.

Recommendations and Reviews

Besides licensing and experience, you should also consider the electrician’s reputation. Consulting online platforms that provide ratings and reviews can give you an idea of the electrician’s reputation.

Services that deliver free quotes from numerous top-rated electricians enable you to compare and select the most suitable electrician based on their reviews and ratings.
