Peter,

"dodgy" is a word I can appreciate, and I understand your concerns.
But despite my flippant tone, I would like to do this properly for a
variety of reasons

I had a second look at some other cable I have. I thought it was
just heavy-duty data cable, but I see it's way better than that. 25m
of monstrous Olflex Classic 100 CY 4G40 that my brother rescued
undamaged for me from a demolition

as well as some lengths of Olflex 2-core + braid, more than I need,
and the application is only 100W max

Outstanding ! God bless scavengers !

The cable I was thinking of using, before looking up the Olflex, is in two
types - black fig8 and red fig8, both 1.something mm solid core. Don't
need that anymore it seems

I shall now be able to supply a cable Earth to the remote point. As
suggested, it was going into conduit as well
