CMS "C" Style to IEC RCD (10A/30mA)

CMS C Style to IEC RCD (10A/30mA) – Modular AC Protection for DIY RV and Caravan Electrical Systems

Integrated Residual Current Protection for Safer 240V Installations

The CMS C Style to IEC RCD (10A/30mA) combines a pre-wired IEC C13 output with a built-in 30mA residual current device, providing essential earth-leakage protection in a compact, modular format. Designed for DIY builders and installers working on motorhomes, caravans, campervans, and off-grid cabins, this unit simplifies compliance with Australian and New Zealand electrical standards while reducing the need for extended electrician involvement.

Unlike generic inline RCD adapters, this CMS component integrates directly into your vehicle’s fixed wiring via the C-style connector system. The result is a cleaner, more professional installation that maintains full circuit protection without bulky external boxes or unreliable plug-in solutions. By incorporating the RCD at the point of distribution, you protect all downstream power points and appliances from earth leakage faults, a critical safety measure in mobile and confined living spaces.

Streamlined DIY Installation with Pre-Sealed Cable Ends

CMS Electracom has engineered this cable for straightforward, tool-friendly fitting. Pre-sealed cable ends eliminate the need for crimping or soldering, allowing you to connect the unit using only standard tools. The modular C-style interface clicks into compatible CMS power points and distribution boxes, enabling a flexible, expandable 240V system that can be installed during the build phase and easily reconfigured later.

• Pre-sealed terminations for secure, low-resistance connections
• Tool-free mating with CMS C-style sockets and power points
• Soft wiring approach allows multiple power points to be linked on a single circuit
• Extra cable length recommended for ease of fitting and future servicing

Designed for Australian Conditions and Standards

This RCD cable is built to meet the requirements of AS/NZS 3000 and relevant electrical safety standards, giving you confidence that your installation aligns with regulatory expectations. The 30mA trip threshold is the recognised level for personal protection against electric shock, making it suitable for use in high-risk areas such as kitchens, bathrooms, and outdoor outlets within your vehicle or tiny home.

Each circuit must be protected by a 16A circuit breaker or RCD, and this unit is rated for 10A continuous load, making it ideal for powering standard 240V appliances like kettles, toasters, chargers, and entertainment systems. The white enclosure is durable and compact, designed to be mounted in a 32mm recess depth, ensuring a flush, unobtrusive fit within cabinetry or wall panels.

Applications Across Mobile and Off-Grid Setups

Whether you are fitting out a new caravan, upgrading an older motorhome, or building a tiny house, this C Style to IEC RCD provides a reliable, code-compliant power solution. It is particularly well suited to:

• Caravans and camper trailers requiring fixed 240V circuits
• Motorhomes and RV conversions with multiple power points
• Marine vessels needing compact, corrosion-resistant electrical components
• Off-grid cabins and tiny homes with limited space for switchboards
• Mobile workshops and food vans where safety and portability are essential

Important Compatibility Note

This cable uses the CMS C-style connector and does not fit Jayco "J" type connectors. Always verify your existing power point interface before ordering to ensure seamless integration. For Jayco-specific systems, alternative CMS adapters are available.

Why Choose a Modular RCD Solution?

Traditional fixed-wire installations often require an electrician to mount, wire, and test a separate RCD unit, adding time and cost to your build. The CMS C Style to IEC RCD simplifies this process by combining the protection device and output lead into one pre-assembled, plug-and-play module. This reduces potential wiring errors, speeds up installation, and makes future maintenance or upgrades far simpler.

By choosing a purpose-built component from CMS Electracom, you avoid the compromises of generic adapters that may not be rated for continuous mobile use or may lack the mechanical robustness needed for life on the road. The secure C-style connection resists vibration and accidental disconnection, a common failure point in vehicle electrical systems.

Power Up Your Build with Confidence

Equip your RV, caravan, or off-grid project with the CMS C Style to IEC RCD (10A/30mA) and enjoy the peace of mind that comes from a professionally engineered, standards-compliant protection device. Whether you are a seasoned DIY installer or working with a qualified electrician for final sign-off, this cable streamlines the path to a safe, reliable 240V system. Add it to your build plan today and take the next step toward a fully powered, adventure-ready vehicle.
