3 Core and Earth Cables for Advanced Wiring

When a two-way switch is required for a lighting circuit, 3 Core & Earth cables are the go-to solution for professional electricians. This specialized cable is the standard for more complex wiring installations, providing a third insulated conductor, or 'switched live,' in addition to the traditional live and neutral wires, plus a bare earth conductor. This construction makes it ideal for staircase lighting, hallway circuits, and other setups where a single light fixture needs to be controlled from two different points. Its robust design ensures a safe and durable installation, providing the peace of mind that comes with using the correct component for the job.

We stock a variety of cross-sectional areas, including the common 1.5mm² and 2.5mm² sizes, to accommodate a wide range of electrical loads and applications. Every cable in our inventory is manufactured to meet stringent British Standards, guaranteeing reliable performance and compliance with all UK wiring regulations. We are dedicated to providing electricians and DIY enthusiasts with the right products for their projects. We offer fast and dependable UK-wide delivery, ensuring you have the components you need to complete your installation on time.
