Cable size table

If you are struggling to work out your old cable size we recommend looking for any markings on the outer insulation. These may be an Amp rating (ie: 20A, 16.5A) or a number followed by mm² or AWG. This will enable you to match the specifications of the cable like for like. If there are no markings please see our tables below that may help determine your cable size. 

Please note - These measurements are based on our cable manufacturer's specifications and other manufacturers may differ. Maximum overall cable diameter is based on the measurement across the insulation and is a rough guide.
