Cable Sizes

4 May 2023

Different cable manufacturers use different thicknesses of insulation on their cables so we have made the chart below to give you an idea of the sizes of our cables.

Firstly, we have the mm² of the cross sectional area of the copper, then we have the thickness of our cable with the insulation and then the amperage rating of that cable over a metre.

If you want to work out which cable you will need for a certain application, click here to use our calculator for working this out.
