Yes, quite possibly. Mind you, his original suggestion was to use 1.5mm 3-core SWA - and if he'd done any research at all, he would have already discovered that even that would probably cost him £400+. Mind you, it's the trench, not much less than quarter of a mile, that would probably worry me a lot more than the SWA!The op has not been heard from for a while now, I reason that he had about 30 quids worth of cable ran across to his shed, this discussion is probably shocking to him since we all discussing how many thousands of pounds the materials will cost.
Bet he will just replace the chewed cable with a new one
Kind Regards, John.
