Switchboard Installation & Upgrades Across the Hills District
FMZ Electrical replaces ageing fuse boxes with modern, compliant switchboards for homes and businesses in Dural, Glenorie, Castle Hill, Kenthurst, Baulkham Hills and across Sydney. Many Hills homes built in the 1970s to 1990s still run ceramic fuses with little or no safety switch protection. A switchboard upgrade adds RCD protection to every circuit, frees up capacity for new appliances and brings your home in line with the AS/NZS 3000 Wiring Rules.
Switchboard Modernisation: Fuses to RCBOs
Our modern switchboard installs use quality RCBOs, a combined circuit breaker and safety switch on each circuit. With RCBOs, one faulty appliance no longer blacks out the whole house, and fault finding is faster. Each circuit is clearly labelled, and you receive a Certificate of Compliance for Electrical Work (CCEW) on completion.
Switchboard Upgrades for Solar, Batteries & EV Chargers
Planning solar, a home battery or an EV charger? We’ll check your board, main switch and consumer mains first, then upgrade the switchboard so your installer can connect without delays. Ask us about dedicated circuits and power points for EV charging in the garage.
Commercial Switchboard Installation & Upgrades
For shops, offices, warehouses and farms, we install and upgrade commercial switchboards, distribution boards and sub-mains. We work to staged timelines that keep your downtime short. Load assessments, thermal checks and surge protection are available.
Safety Switch (RCD) Installation & Circuit Breaker Replacement
If your board is in good condition but missing protection, we can add safety switches or replace faulty circuit breakers without a full upgrade. For more detail, read our guide: the benefits of upgrading your switchboard.

Frequently Asked Questions
How much does a switchboard upgrade cost in Sydney?
A standard residential switchboard upgrade in Sydney typically costs between $1,200 and $2,500. That usually covers a new enclosure, main switch, RCBOs or safety switches and testing. Larger homes, three-phase supply, asbestos backing boards or meter panel relocations cost more. We give you a fixed written quote after a free on-site inspection. These are typical Sydney industry figures only. Costs can vary depending on your property and requirements, and your exact price is confirmed in writing after a free inspection.
Do I need a switchboard upgrade for solar panels or a battery?
Often, yes. Solar inverters, home batteries and EV chargers need spare circuit capacity, correct isolation and compliant RCD protection. Older boards with ceramic fuses or no room for extra breakers usually need upgrading before a solar or battery installer can connect.
Do you install commercial switchboards?
Yes. We design, supply and install commercial and light industrial switchboards, distribution boards and sub-boards for shops, offices, warehouses and farms, including three-phase supply, metering and load assessments.
What are the signs my switchboard needs replacing?
Ceramic or rewireable fuses, scorch marks, a burning smell, buzzing, frequent tripping, flickering lights, no safety switches, or an old black asbestos-type backing board are all signs it’s time to upgrade.
