Switchboard Upgrades Perth

Some common signs you need a switchboard replacement include flickering lights, frequent tripping, the lack of safety switches (RCDs), burning smells, scorch marks or buzzing sounds.

If you notice burning smells, scorch marks or buzzing, it’s important that you contact an emergency electrician.

An RCD, or Residual Current Device, is a critical safety switch that monitors the flow of electricity through your circuits. If it detects a fault such as electricity leaking through a person, damaged wiring, or a faulty appliance, it cuts the power almost instantly.

If your switchboard does not have RCD protection or only has partial coverage, it is worth considering a switchboard upgrade or an RCD check to ensure each circuit is properly protected and compliant.

During a switchboard upgrade, we will need to turn off your power to ensure the work is carried out safely. In most cases, the power is off for a few hours, and we work efficiently to minimise disruption and restore electricity as quickly as possible once the upgrade is complete.

While it won’t directly reduce energy usage, a modern switchboard improves efficiency, preventing power wastage and electrical damage.

Residential upgrade costs typically range from $700 to $2,000 for standard installations. For complex three-phase systems or high-demand properties, you can expect $2,000–$3,500+

The difference between single and three-phase switchboards is the number of active wires supplying power.

A single-phase switchboard supplies power using one active wire and is common in most standard homes with typical power needs. It is suitable for lighting, power points, and everyday use, including some modern appliances.

A three-phase switchboard uses three active wires to deliver power more evenly and efficiently. It is often required for larger homes, commercial properties, or properties running multiple modern appliances, EV chargers, large air-conditioning systems, workshops, or machinery. Upgrading to three-phase can help prevent overloading and allow for future electrical upgrades.

The switchboard installation process starts with a thorough on-site inspection by a licensed electrician. Your existing switchboard, wiring, and power circuits are assessed for safety risks, outdated components, and compliance with current safety standards. The old fuse box or switchboard is then removed and replaced with a new switchboard fitted with modern RCBO’s (Circuit breaker / RCD Combo’s). All electrical work is tested before power is restored to ensure everything is functioning correctly.
