Surface cable 2.5mm

A 2.5mm Surface Cable is primarily an indoor electrical power cable used for fixed installations. It is a type of \"Twin and Earth\" or \"Surfix\" cable designed for domestic and commercial wiring. While it can be used on the surface of walls (hence the name \"surface cable\"), it is not a fibre optic cable, nor is it typically rated for unprotected outdoor use or underground burial unless it is the \"Armoured\" (SWA) version.\n\nIn most buildings, this specific size (2.5mm²) is the standard for power socket circuits (ring mains) because it can safely handle the high current required for appliances like microwaves, heaters, and air conditioners. It consists of solid or stranded copper conductors insulated with PVC, often with a secondary outer layer for added protection when clipped directly to a wall or run through trunking.
