JENGA POWER CABLE 4.0mm

Electrical power cables are categorized by their cross-sectional area and core configuration to suit specific load requirements and installation environments. 1.5 mm² cables are the standard for residential lighting circuits, available as singles (individual insulated wires used in conduit) or twins (two insulated cores in one sheath), providing sufficient capacity for LED and incandescent fixtures. 2.5 mm² cables, also found in single or twin configurations, are the workhorses of domestic power, typically utilized for standard socket outlets and ring main circuits due to their higher current-carrying capacity. As electrical demands increase, larger diameters like 4 mm² and 6 mm² become necessary; 4 mm² is often used for high-power appliances like electric ovens or specialized power circuits, while 6 mm² is common for heavy-duty cooking ranges and small shower units. For the most demanding domestic applications, such as high-kilowatt electric showers or sub-main supplies to outbuildings, 10 mm² cables are employed to minimize voltage drop and safely handle high thermal loads over longer distances.
