Note: The values below are approximate for general multi-core PVC insulated cables (Copper) installed in air or conduit, based on typical IEC 60364-5-52 derating factors. Always consult specific manufacturer datasheets.

Electrical cables are the arteries of any power distribution system. The selection of the correct cable size is critical for safety, efficiency, and cost-effectiveness. An undersized cable leads to overheating, insulation failure, and fire hazards, while an oversized cable results in unnecessary material costs and installation difficulties. cable size chart mm2

The table below provides a general guide for copper cable sizes and their typical current-carrying capacities under standard conditions (single-phase, clipped to a surface). Cable Size (mm²) Current Rating (Amps) Common Application 10A – 14A Standard lighting circuits, fans 1.5 mm² 15A – 18A Two-way lighting switches, small appliances 2.5 mm² 20A – 24A Mains sockets, ring main circuits, washing machines 4.0 mm² 25A – 32A Air conditioners, high-power kitchen circuits 6.0 mm² 32A – 41A Electric cookers, showers, large appliances 10 mm² 50A – 57A

This chart provides general guidelines for common household and automotive applications. Ratings can vary based on insulation type and installation method. Cable Size ( mm2m m squared Approx. Amp Rating Typical Applications depending on: Note: The values below are approximate

Choosing the correct cable size is one of the most critical steps in any electrical project, from simple home repairs to large-scale industrial installations. Using an undersized cable can lead to overheating, fires, and equipment failure, while over-sizing leads to unnecessary costs and installation difficulties.

While ampacity ensures the cable does not melt, voltage drop ensures the equipment works. As current travels down a cable, resistance causes a drop in voltage. If the drop is too high (>3-5%), equipment may malfunction.

A simple chart isn't always enough. Professional electricians use several "derating factors" to determine the final required size. Stephen P Wales Ltd Cable Size & Current Rating Chart - Spwales.com
