I'm not even sure the 12 pin plug is rated to 20A:eek:
must check that one day:D

for info... I just checked my 12 pin Narva: 7 pins are rated at 15 Amp while the remaining 5 are rated at 35 Amp...
cheers

I'd be surprised if the standard wiring could not deliver the current required. It is a matter of how hot the wire will get. Sure there will be a voltage drop but I think the melting insulation is going to be your first problem. And I think the electromagnets are going to be your current limiters. The electromagnets in the brakes are going to have much thinner wire and a much longer length of wire as it is wound multiple times around the metal core.

This is what i have just dóne, but I ran 6mm dual core which fits nicely in the large round 7 pin trailer plug.
