RCD & Loop Testers

RCD and loop testers are essential tools for verifying the effectiveness of circuit protection in electrical installations. Designed for use by professional electricians, these testers accurately measure earth loop impedance and check the correct operation of residual current devices (RCDs), helping ensure systems disconnect safely under fault conditions. Suitable for domestic, commercial, and industrial environments, RCD & loop testers support compliance with 18th Edition Wiring Regulations. With clear displays and user-friendly features, they deliver fast, reliable results. Explore high-performance RCD and loop testers available now at CEF.
