The Four Steps Of Electrical Safety and Protection
Find out how Clipsal’s new MAX9 switchboards helps builders deliver safer Australian homes with the ‘four steps of safety’: RCBOs, Surge Protection, Arc Fault Detection, and new energy support.
Australian homes are changing faster than ever, and the electrical switchboard is now carrying more responsibility than at any point in the past. The new Clipsal MAX9 switchboards have been rebuilt specifically to handle this reality — giving you a better way to deliver the four steps of protection your clients now need.
How to use the new MAX9 Switchboards to deliver safer, smarter homes
Australian homes are changing faster than ever and the electrical switchboard is now carrying more responsibility than at any point in the past. According to the Energy Efficiency & Conservation Authority (2023), today:
- 36% of employed Australians work remotely or hybrid, driving higher daytime energy use
- Around 40% of Australian homes already have rooftop solar
- 92% of EV owners charge at home at least some of the time
- The average home contains $15,000–$20,000 worth of sensitive electronics
Everything is going electric. And as solar, batteries, EV chargers, heat pumps and smart home systems are added, the switchboard “cops all the load”. The new Clipsal MAX9 switchboards have been rebuilt specifically to handle this reality — giving you a better way to deliver the four steps of protection your clients now need.
Step 1: Protect People & Wiring with RCBOs
Electrical faults remain one of the biggest residential risks in Australia:
- According to the New South Wales Government, around 40% of house fires are caused by electrical faults.
- Many incidents relate to overloaded, ageing or poorly protected circuits
Modern protection starts with RCBOs (Residual Current Breakers with Overcurrent protection) — one per circuit — to protect both people and cables. The new MAX9 switchboards are designed to support RCBO based layouts properly:
- More than 40% extra space under DIN rails
- Up to 30% more space between DIN rails
- 2× space for outgoing cable terminations
This additional space matters. It means:
- Cleaner RCBO installation
- Better heat management
- Easier fault finding
- Reduced stress on cables and terminals
Step 2: Protect Appliances & Technology with Surge Protection
Modern homes are packed with electronics, many of them connected and sensitive to voltage fluctuations. Power surges caused by lightning, grid switching or large appliances can damage equipment instantly — or slowly degrade it over time.
Surge protection is no longer a premium upgrade. It’s an expectation. MAX9 switchboards are designed to integrate surge protection devices (SPDs) cleanly:
- Space and layout allow SPDs to be installed neatly
- Internal organisation keeps surge protection accessible and compliant
- Robust enclosures protect devices once installed
With homes holding $15,000–$20,000 worth of electrical equipment, this single layer of protection can make a meaningful difference (New South Wales Government, n.d.).
Step 3: Reduce Fire Risk with Arc Fault Detection
Electrical fires continue to be a serious issue:
- Around 12,000 residential fires occur every year
- 40% are linked to electrical faults or appliances
- Home fire damage is estimated at $700 million annually
Many fires begin with arc faults — tiny electrical sparks caused by damaged wiring, loose connections or ageing cables. These faults often sit below the trip level of traditional breakers. The new MAX9 switchboards are designed to comfortably accommodate Arc Fault Detection Devices (AFDDs) where higher fire protection is required:
- Increased internal space supports wider devices
- Strong DIN rails and fixings support heavier protection devices
- Clean layouts support selective AFDD installation on high risk circuits
This makes AFDDs a practical option for:
- Family homes
- Rural and acreage builds
- Timber-framed construction
- Homes with valuable or irreplaceable contents
Step 4: Be Ready for New Energy & Growing Loads
Australia’s electrification trend is accelerating:
- 4.1 million rooftop solar systems installed, with strong growth continuing
- 100,000–150,000 batteries forecast in 2026
- 15–19% of new vehicle sales expected to be EVs by 2026
These technologies introduce:
- More circuits
- Bigger breakers
- Thicker cables
- Bidirectional energy flow
The new MAX9 switchboards are built for expansion:
- 100A rated neutral and earth bars for higher load capacity
- Seamless integration with MAXBAR+, grouping grid, solar, battery and EV sources safely
- Support for single phase and three phase residential installations
- Space to grow as upgrades are added over time
The switchboard is no longer just a compliance item. It’s the heart of a modern, electric home. Find out more about Clipsal MAX9 today and start delivering on the four steps of electrical safety and protection for your clients.
