Residential Electrical Cable

Electrical cable is an assembly of one or more insulated copper or aluminium conductors used to carry power or control signals in buildings. Types differ by insulation (PVC, XLPE), flexibility, and fire performance. Selection depends on voltage, current, installation method, and applicable IEC, BS, or EN standards.

FAQ

What is the difference between PVC and XLPE cable?
PVC insulation is rated to about 70°C conductor temperature, while XLPE (cross-linked polyethylene) is rated to about 90°C, allowing higher current or lower temperature rise. XLPE also offers better resistance to heat and chemical ageing.
How are cable sizes chosen?
Cross-sectional area (mm²) is selected from the load current, the installation method, grouping, and ambient temperature, then checked against voltage drop limits. Sizing should follow the relevant wiring regulations and manufacturer current-rating tables.
