1.5mm Three Core and Earth Grey PVC Cable 100m
Three core and earth cables are mainly used for two-way lighting installations and in other situations that require a permanent and switched live along with a neutral, such as central heating, some types of lighting and extractor fans. This 100-metre single-reel spool delivers complete cable runs for complex switching circuits without mid-span splices, making it ideal for two-way lighting circuits, such as stairs and landings, and multi-switch control installations.
- 1.5mm² Cross-Section: Sized for durability and fixed domestic wiring, with a current rating of 16 amps for standard lighting and control circuits in homes and light commercial buildings.
- Three Insulated Cores Plus Earth: Includes three insulated conductors plus an earth conductor, which gives installers an extra core for more complex switching arrangements. Colour coded: brown, black, grey, and bare earth cores.
- Grey PVC Sheath: Designed to be protected by a robust, insulated PVC sheath that provides mechanical and environmental protection during installation and long-term service.
- 100-Metre Reel: Eliminates the need for terminal boxes and joint splices across longer runs—a reliability advantage in staircases, landings, and extended heating control circuits.
- BS 6004 & BASEC Certified: Meets British Standard BS 6004 for electric cables used for domestic and light industrial wiring, covering insulated and sheathed cables with voltage ratings of up to 300/500 V, ensuring safety, reliability, and performance of cables commonly used in fixed installations.
- Plain Copper Conductors: High-conductivity solid copper cores ensure consistent electrical performance and durability over the cable's service life.
The extra core makes three core and earth especially useful for two-way lighting, extractor fan wiring, and heating controls that need permanent live, switched live, and neutral conductors. Two-way switching is where three core and earth is the practical choice because twin and earth lacks the extra insulated core needed between switches. Unlike alternative cable types, this configuration reduces installation complexity and minimizes the risk of connection errors on complex circuits—critical for electricians and contractors working on multi-switch installations in residential and small commercial properties.
1.5mm Three Core and Earth Grey PVC Cable 100m – Fixed Wiring for Two-Way Lighting & Controls
Three Core and Earth Cables are mainly used for two-way lighting installations and in other situations that require a permanent and switched live along with a neutral, such as central heating, some types of lighting and extractor fans. This 100-metre single-reel spool eliminates the need for multiple joins on complex switching circuits—a critical advantage for electricians and contractors installing two-way lighting on staircases, landings, and multi-switch control zones.
Why Choose Three Core & Earth Over Twin & Earth
3 Core & Earth cable includes three insulated conductors plus an earth conductor, which gives installers an extra core for more complex switching arrangements. That added core makes it especially useful for two-way lighting, extractor fan wiring, and heating controls that need permanent live, switched live, and neutral. For two-way switching, 3 Core & Earth is the practical choice because Twin & Earth lacks the extra insulated core needed between switches. This means fewer conduit runs and reduced installation complexity compared to standard alternatives.
Technical Specification & Build Quality
The 1.5mm² cross-section is sized for standard domestic and light commercial lighting circuits. The three core and earth cable are colour coded and has 3 sheathed conductors brown, black, grey and 1 bare earth conductor. The 3 Core and Earth cables are designed to be protected by a robust, insulated PVC sheath. All cores are colour-coded for rapid identification during installation, reducing wiring errors on site.
Why 100 Metres on One Reel
The full 100-metre length covers longer cable runs without terminal boxes at mid-span, particularly valuable for extended staircase circuits and heating control runs. Fewer joints mean fewer weak connection points where faults can develop—a reliability advantage that matters in both residential and commercial installations.
Standards Compliance
The British Standard BS 6004 outlines the specifications for electric cables used for domestic and light industrial wiring. It covers insulated and sheathed cables with voltage ratings of up to 300/500 V. This standard ensures the safety, reliability, and performance of cables commonly used in fixed installations, specifying materials, dimensions, and testing methods to comply with regulatory requirements. This cable meets BASEC and BS 6004 certification, ensuring it's compliant with modern UK wiring regulations for fixed installations in homes, offices, and light commercial spaces.
1.5mm Three Core & Earth Grey PVC Cable – 100m Fixed Wiring Spool
Designed for two-way lighting, central heating controls, and extractor fan wiring. This 100-metre spool delivers the versatility electricians and contractors need for complex switching installations without excessive joins. Three Core and Earth Cables are mainly used for two-way lighting installations and in other situations that require a permanent and switched live along with a neutral, such as central heating, some types of lighting and extractor fans.
What Makes 3-Core & Earth Different from Twin & Earth
3 Core & Earth cable includes three insulated conductors plus an earth conductor, which gives installers an extra core for more complex switching arrangements. That added core makes it especially useful for two-way lighting, extractor fan wiring, and heating controls that need permanent live, switched live, and neutral conductors. This extra core eliminates the need for additional conduit runs in multi-switch scenarios, saving time and reducing installation complexity compared to standard twin & earth alternatives.
Specification & Build Quality
The 1.5mm² cross-section is sized for standard domestic lighting circuits and light power loads. The three core and earth cable are colour coded and has 3 sheathed conductors brown, black, grey and 1 bare earth conductor. The 3 Core and Earth cables are designed to be protected by a robust, insulated PVC sheath. All three insulated cores plus bare earth conductor are colour-coded for quick identification during installation, reducing wiring errors.
100m Single Reel Advantage
The full 100-metre length on one reel covers longer cable runs with fewer joints, directly reducing installation points where weak connections can develop. This extended length suits stairs, landing circuits, and extended heating control runs without requiring terminal boxes at mid-span.
Standards Compliance & Safety
The British Standard BS 6004 outlines the specifications for electric cables used for domestic and light industrial wiring. It covers insulated and sheathed cables with voltage ratings of up to 300/500 V. This standard ensures the safety, reliability, and performance of cables commonly used in fixed installations, specifying materials, dimensions, and testing methods to comply with regulatory requirements. The three insulated conductors are typically used for carrying live, neutral, and additional control or switched lines, while the bare copper wire or the one with green/yellow insulation serves as the earth conductor. The purpose of this earth wire is to safely discharge leakage currents into the ground in the event of a fault, thereby protecting both people and equipment.
Installation Applications
Ideal for fixed internal wiring in walls, ceilings, or run through conduit and trunking. The 1.5mm² gauge suits standard domestic circuits where load calculations confirm its suitability, and the grey outer sheath integrates cleanly with neutral décor during surface runs.
