Two-core : This type of cable is designed for connecting small appliances that are double insulated and do not require an earth connection. It features two conductors: one live (usually brown) and one neutral (typically blue). The cable is flexible and has a circular shape, covered by a protective outer sheath. Both conductors are insulated with color-coded PVC, ensuring easy identification and safe operation. This makes it ideal for use in various domestic and light commercial applications where mobility and convenience are essential.
