Current regulations require consumer units to include Residual Current Devices (RCDs) to provide protection against electric shock and fire risks. In addition, surge protection is now a key requirement under the wiring regulations (BS 7671), especially for industrial sites where valuable equipment and sensitive electronics are at risk. Surge protection devices (SPDs) safeguard against sudden voltage spikes caused by lightning strikes or power fluctuations, helping prevent costly damage and downtime. By upgrading to a compliant unit with RCDs and SPDs, you ensure your site meets legal obligations while protecting critical machinery and infrastructure.
