Our range of RCDs & Residual Current Devices offers essential safety circuit protection for domestic, commercial, and light industrial electrical systems. Designed to quickly disconnect the supply in the event of a fault, RCDs help reduce the risk of electric shock and fire. This collection covers reliable options commonly used in UK installations, suitable for upgrades, replacements, and new builds.

Within this collection you’ll find residual current devices suited to consumer units and distribution boards, covering common configurations used by trade electricians and competent DIYers. Whether you are working on a full rewire or replacing an existing protective device, these RCDs are chosen to meet everyday installation needs rather than niche applications.

RCDs are widely used across homes, offices, workshops, and rental properties where additional protection against earth leakage is required. Typical use cases include socket circuits, outdoor power supplies, garage and garden feeds, and areas where electrical equipment may be exposed to moisture. They are a key part of maintaining a safe and compliant electrical system.

When choosing an RCD, it’s important to check the required current rating, sensitivity level, and the type needed for the circuit it will protect. You should also consider whether you are replacing a like-for-like unit within an existing consumer unit, as physical format and fixing method can vary between designs.

The RCDs in this collection are sourced for their suitability within standard UK consumer units and boards. If you are pairing with other protective devices such as MCBs or RCBOs, ensure compatibility within the same assembly to maintain correct operation and a tidy installation.

If you’re unsure which residual current device is right for your project, our team is happy to help with practical advice before you buy. Get in touch to discuss your requirements or fill out our contact form and we’ll come back to you.
