The Importance of Surge Protection Devices at Switchboards
Protection Against Voltage Spikes
Electrical surges can occur from various sources, including lightning strikes, utility switching, and even the operation of large appliances. SPDs mitigate these risks by limiting the voltage that reaches your sensitive equipment, protecting against a range of surges.
Equipment Longevity
Frequent voltage spikes can lead to premature failure of electronic devices. By using SPDs, you can extend the lifespan of your electrical appliances and electronic devices, reducing replacement costs.
Increased Safety
By protecting your electrical system from surges, SPDs contribute to overall safety, reducing the risk of electrical fires and equipment malfunctions.


How Surge Protection Works
Surge protection devices work by diverting excess voltage away from your home’s electrical system. When a power surge occurs, the SPD detects the increased voltage and redirects it safely to the ground through the earthing system, preventing it from reaching your electronic devices.
Common Sources of Power Surges
- Lightning Strikes: Direct or nearby lightning strikes can cause significant voltage spikes.
- Power Lines: Issues with power lines, such as downed lines or transformer failures, can lead to surges.
- Electrical Appliances: Large appliances like air conditioners or refrigerators can cause internal surges when they switch on or off.
Why Surge Protection Is Essential
Protect Your Electronic Devices
Electrical surges can damage or destroy your electronic devices and appliances. Surge protection devices safeguard your electrical appliances, computers, and other electronic devices from voltage spikes caused by lightning strikes, power surges, and fluctuations in power lines.
Prevent Electrical Fires
Power surges can lead to overheating and electrical fires. Reliable surge protection minimises the risk of electrical fires by preventing excessive voltage from reaching your electrical systems.

Common Pitfalls with Surge Protection

Understanding Surge Protection Devices at Switchboards
Surge Protection Devices (SPDs) are essential components of modern electrical systems. They act as a barrier between the power supply and your devices, absorbing and dissipating excess energy from electrical surges. Installing SPDs at switchboards is crucial for ensuring the longevity and safety of your electrical systems.
Types of Surge Protection Devices
- Type 1 SPDs: Installed between the utility supply and the electrical system, offering the first line of defence against external surges like lightning strikes.
- Type 2 SPDs: Typically installed at the main switchboard, protecting against residual surges after the first line of defence.
- Type 3 SPDs: Installed at the point of use, such as in power strips or directly at devices, providing additional protection for sensitive electronics.
Cheap vs. Quality Surge Protectors
