WHY IT MATTERS

Your old fuse box could be putting your family at risk.

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.

Signs You Need a Switchboard Upgrade

Frequent trip-outs mean your board can’t handle current loads

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

Pre-1990s boards weren’t built for modern electrical demands
OUR SWITCHBOARD SERVICES

Everything Switchboard, Covered.

Whether it’s a straightforward fuse box swap or a full three-phase upgrade for a commercial premises, GNM Electrical handles it all.

Fuse Box to Circuit Breaker Upgrades

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.

Safety Switch (RCBO) Installation

RCBO’s save lives. We install safety switches on all circuits as required by NSW regulations, and can test and certify existing switches.

Three-Phase Switchboard Upgrades

For larger homes, granny flats, or commercial properties needing high-power equipment — we upgrade to three-phase supply and install commercial-grade switchboards.

Switchboard Capacity Upgrades

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.

Compliance Certificates & Inspections

Need a Certificate of Compliance for a property sale, rental, or insurance claim? We inspect existing switchboards and issue certificates for compliant installations.

Switchboard Relocations

Renovating and need the board moved? We handle complete switchboard relocations with minimal disruption — all metering and supply coordination included.

I had a new cooktop and a heat light exhaust fan installed and I’m very happy with the service provided. They arrived on time, explained the installation process clearly and completed everything efficiently and professionally. The cooktop was installed neatly and works perfectly. The heat light fan in the bathroom was also fitted with great attention to detail and it makes a big difference in ventilation and warmth. Everything was left clean and tidy after the work was finished. Overall, the workmanship was excellent and the whole experience was smooth from start to finish. I would definitely recommend their services to anyone needing appliance or electrical installations.

Cameron was quick, professional, and very helpful. He responded quickly, came out the same day to inspect the issue, and clearly explained what the problem was with the main switch overheating. He replaced the faulty switch, fixed the wiring, and tested everything to make sure it was working properly. The work was done neatly and efficiently. The price was very reasonable and the whole process was smooth. Great service and highly recommended.
