Re: Mains installation in garden

Yes, I think you hit the point there.  I'd not grasped that a doubling
of diameter halves resistance.  The max distances I was quoted were
based on 2.5mm2 wire.  The company also does a 4mm2 wire.  Looking at
that it may just be ok for a 14m run.  Mind you 4mm2 strikes me as
pretty chunky stuff. I'll check with them tomorrow.
