What is an SPD?
An SPD (Surge Protection Device) protects electrical systems from power surges caused by lightning, faults, or sudden voltage spikes. These surges can damage equipment or disrupt operations. SPDs help by diverting the excess voltage away from your circuits, reducing the risk of damage. Historically, surge protection became crucial as electrical systems became more complex, especially in commercial and industrial environments.
With the 18th Edition of BS7671 Wiring Regulations, surge protection is now a requirement in many installations. According to BS7671 Regulation 443.4, SPDs must be installed in buildings where a surge could cause serious damage. This includes installations protecting human life, public services, or sensitive equipment. SPDs play a key role in protecting your electrical system, preventing costly damage and downtime.
