Is your home’s safety stuck in the past? 🛑⚡
Another day, another switchboard upgrade here in Hamilton! 🛠️
We replaced these dated MCBs with a modern, fully compliant setup built for today’s high-demand homes.
The big difference? Those old MCBs (in the first photo) were designed to protect your cables from overheating, but they don't offer the same level of people protection as modern RCBOs.
By upgrading to individual RCBOs for every circuit (in the second photo), we’ve given this home the "Gold Standard" of protection.
Why this upgrade is a game-changer:
⚡ Total Protection: RCBOs monitor for "earth leakage"—they trip in milliseconds if they detect a fault, preventing potentially fatal shocks.
⚡ Better Fire Safety: Modern components are far more sensitive to overloads from high-power appliances like heat pumps and EVs.
⚡ Smart Isolation: If one circuit has a fault, only that switch trips. You won't be left in total darkness hunting for a torch!
⚡ Insurance & Compliance: All work is done to AS/NZS 3000 standards, and a digital Certificate of Compliance (CoC) was issued on the spot.
If your board still looks like the “Before” photo, your home might be “working,” but it isn’t as safe as it could be. 👀
