Still running on an old fuse box? It’s not just outdated — it could be a serious safety and insurance risk. GNM Electrical upgrades switchboards across residential and commercial properties across Sydney.
We’ll contact you within 5 minutes.
A modern switchboard upgrade installs RCD-protected circuit breakers that detect faults in milliseconds and shut down power before you’re hurt. It’s the most important electrical upgrade a Sydney homeowner can make.
These are obsolete and provide minimal safety protection
Legally required in NSW for new installations since 2000
Your board needs capacity before new circuits are added
We replace old ceramic fuse boxes with modern, fully-labelled DIN-rail switchboards fitted with Clipsal or equivalent quality MCBs and RCDs. Clean, safe, compliant.
RCBO’s save lives. We install safety switches on all circuits as required by NSW regulations, and can test and certify existing switches.
For larger homes, granny flats, or commercial properties needing high-power equipment — we upgrade to three-phase supply and install commercial-grade switchboards.
Adding a pool, EV charger, ducted air-con or solar system? We assess your current board and upgrade the capacity and circuit layout to safely handle the additional load.
Need a Certificate of Compliance for a property sale, rental, or insurance claim? We inspect existing switchboards and issue certificates for compliant installations.
Renovating and need the board moved? We handle complete switchboard relocations with minimal disruption — all metering and supply coordination included.
