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

    This is a new van. Fiat ducato. The engine battery is under the passenger foot well same as most vans and the fuses are attached to the battery. 

    the leisure battery is not in a seal box but under the passenger seat. It is a lead acid battery but a sealed one. No chance electrolyte spillage. They are designed to be installed like this. I will be changing this to lithium soon again sealed battery.
