How is cable measured in mm2?
In Europe, wire and cable sizes are expressed in cross sectional area in mm2, and also as the number of strands of wires of a diameter expressed in mm. For example, 7/0.2 means 7 strands of wire each 0.2mm diameter. This example has a cross sectional area of 0.22mm2.
What does 2.5 mm2 cable mean?
2.5mm squared is an annotation which means that the round conductor has an ‘Equivalent’ cross sectional area of 2.5 square millimeters of copper. A ‘ cross section’ is a section formed by a plane cutting through an object, usually at right angles to an axis.
Should I use 1.5 mm or 2.5 mm cable?
1.5 mm is most commonly used for lighting circuitry and switches. 2.5 mm is most commonly used for ring mains, plug and socket wiring. 4 mm is most commonly used for high power ring mains, plug and socket wiring. 6, 10 and 16 mm are most commonly used for high powered small appliances such as cookers.
