SNE cable refers to a specialized type of electrical cable used predominantly in UK electrical installations, particularly for TN-S earthing systems. The name 'SNE' stands for Separate Neutral and Earth, meaning that the neutral (N) and earth (E) conductors are separated throughout the length of the cable—unlike TNC or TNC-S systems where they may be combined.

What is SNE Cable
What is SNE Cable Used For?
SNE cables are primarily used in:
Low voltage distribution networks
TN-S grounding systems
UK-style fused cut-outs
Outdoor overhead or underground service lines
They are widely chosen for domestic connections, utility networks, and rural power supply lines, where earthing and neutral conductors must remain distinct.
Construction of SNE Cable
A typical SNE cable includes:
Phase conductor(s): Usually copper or aluminum
Neutral conductor: Separate insulated core
Earth conductor: Separate bare or insulated conductor
Insulation: XLPE or PVC
Sheathing: Black weather-resistant PVC for outdoor use
Unlike CNE (Combined Neutral and Earth) cables, SNE cables are required when separation of conductors is critical for electrical safety and compliance.
Key Features of SNE Cable
Separate neutral and earth conductors
Compliant with UK Distribution Network Operator (DNO) specifications
Suitable for TN-S grounding
Low voltage (typically rated 0.6/1kV)
Available in single-core or multi-core designs
UV and weather resistant (for outdoor use)
SNE Cable vs CNE Cable
| Feature | SNE Cable | CNE Cable |
|---|---|---|
| Neutral & Earth | Separate conductors | Combined neutral and earth conductor |
| Typical Use | TN-S earthing systems | TNC/TNC-S earthing systems |
| Safety | Higher safety in TN-S networks | Simpler but less isolated design |
| Application | UK utility & DNO requirements | Overhead lines and older networks |
