Cable current rating advice

Former Community Member
Former Community Member
Hi all, I would like to verify something with respect to current carrying capacity of cable. Specifically vehicle single core DC circuits.


Looking at 16mm wire not worrying about voltage drop. manufacturers are ratting this at 110A and on a forum I subscribe to people have been advised 125A is ok.


The cable is rated at 70 deg as shown on the suppliers site linked below.

16mm supplier


Am I wright that this comes under 

Table 4D1A


Single-core 70°C Thermoplastic Insulated Cables, Non-Armoured, with or without Sheath


Reference Method C (clipped direct) This will be between battery to battery not in any conduit or insulation


So is rated as 87A


I would be interested in your advice as it has been several years since I used these tables

    Well  it is quite possible that the installation is neither to BS7671 nor EN 1648, it is quite likely just to auto electrician car standard. You could thread some flexi conduit over the battery leads to achieve a similar effect.
