If your board runs multiple circuits through one or two RCDs with separate breakers, a single fault can drop half the house. RCBOs combine safety-switch and over-current protection per circuit, so only the problem circuit trips.

Benefits you’ll notice immediately
• Fewer blackouts: A toaster fault no longer kills bedroom power or Wi-Fi—only the kitchen circuit trips.
• Faster fault-finding: One circuit = one trip. Easier to spot and fix, fewer return visits.
• Better protection, everywhere: Every circuit gets its own shock and overload protection.
• Keeps essentials on: Fridge, aquarium, home office and heating stay on if another circuit faults.
• Future-ready: Clean, labelled layout ready for EV chargers, solar, heat-pump hot water and renovations.
• Neater board: Modern layout, clear labels, compliance test results at handover.

Great candidates for an upgrade
• You’ve had “mystery” or frequent whole-home trips
• You’re adding big appliances (oven, induction, air-con) or an EV charger
• You work from home and can’t afford outages
• You’re preparing a property for sale or rent

What our RCBO upgrade includes
• RCBOs on each circuit (lighting, power, oven, air-con, outdoors, shed, etc.)
• Board tidy-up and clear circuit labelling
• Full trip-time testing and compliance documentation
• Walk-through of your board and how to use the test/reset buttons

1. Locate the device labelled “Safety Switch” or RCBO.
2. Press the “T” button. Power on that circuit should trip immediately.
3. Reset to restore power.
If it doesn’t trip or won’t reset, book a service.

1. On-site inspection & advice – We assess your switchboard and circuits.
2. Clear quote – Plain language, fixed scope.
3. Licensed installation – Neat, compliant work with minimal downtime.
4. Test & handover – Trip-time tests, labels, and a quick demo of the test button.
5. Aftercare – We’re here for future circuits, appliances, or troubleshooting.
