RCD Adaptors

About RCD Adaptors

RCD adaptors are essential portable safety devices that protect users from electric shock and reduce the risk of electrical fires when working with 240v power tools and equipment. These compact units plug directly into standard UK mains sockets and provide residual current device protection for any tool or appliance connected through them. MyToolShed.co.uk stocks a professional range of RCD adaptors from trusted brands including Draper, Faithfull, Masterplug, Sealey and Handy, suitable for both trade and domestic applications.

An RCD adaptor continuously monitors the electrical current flowing through it and will trip within milliseconds if it detects an imbalance, instantly cutting the power supply. This makes them invaluable for tradespeople working on-site, in outdoor environments, or in locations where fixed RCD protection may not be present. Many models available at MyToolShed feature weather-resistant IP66 ratings for demanding work conditions.

Applications

• Electricians and sparkies working on domestic and commercial installations
• Builders and construction workers using power tools on active building sites
• Groundworkers and landscapers operating equipment outdoors in wet conditions
• Plumbers using electrical tools in potentially damp environments
• Carpenters and joiners requiring portable protection across multiple job sites
• Maintenance technicians servicing equipment in various locations
• DIY enthusiasts undertaking home improvement projects and garden work
• Hire companies providing safe equipment to customers

Choosing The Right RCD Adaptors

When selecting an RCD adaptor, consider the sensitivity rating, typically 30mA for personal protection, which provides the fastest response time for preventing serious injury. Check the current rating matches your tool requirements – most adaptors handle 13A, suitable for the majority of power tools and equipment used by tradespeople.

For outdoor or construction site use, prioritise models with weatherproof ratings such as IP66, which offer protection against dust ingress and powerful water jets. Look for adaptors with in-line designs that allow the plug to remain accessible rather than blocking adjacent sockets. Features like integral test buttons enable regular functionality checks, whilst reset buttons allow quick restoration of power after a trip. Consider branded options from established manufacturers like Sealey and Draper for reliability and compliance with UK safety standards.

Safety Information

Always test your RCD adaptor before each use by pressing the test button – the device should trip immediately. Never use a faulty or damaged RCD adaptor, and replace any unit that fails to trip during testing. Remember that RCD protection significantly reduces electrical shock risk but does not replace proper tool maintenance, regular PAT testing, or safe working practices. RCD adaptors are not a substitute for fixed electrical installation protection and should complement, not replace, existing safety measures.

Frequently Asked Questions

How often should I test my RCD adaptor?

Test your RCD adaptor before each use or at least weekly if in regular use. Press the test button to ensure it trips correctly. If it fails to trip or won't reset, replace it immediately as it may not provide adequate protection.

What's the difference between an RCD adaptor and an RCD socket?

An RCD adaptor is a portable plug-in device offering temporary protection wherever you work, whilst an RCD socket is permanently installed in an electrical system. Adaptors provide flexibility for tradespeople moving between sites or working in areas without fixed RCD protection.

Can I use an RCD adaptor with extension leads?

Yes, you can plug an extension lead into an RCD adaptor to protect multiple tools. However, ensure the total load doesn't exceed the adaptor's current rating, and position the RCD adaptor as close to the mains socket as possible for optimal protection.
