My latest cock-up: Having dug 15M trench, put SWA cable in and re-filled,
I've now discovered it's a 3 core rather than 2 core cable. Doh! (It did seem
a little thick, but I hadn't used any SWA for a while...) I could just go
ahead and use it anyway I suppose, but since the core colours are brown,
black and grey as for 3-phase system, I can't use the correct single phase
colour scheme - there's no blue.

Is there a way round this without digging the whole bloody thing up again?

Just use it, but ensure that the cores are properly marked with tape or
sleeving at their terminations.

The third core can be connected to earth, either at one end or both ends
if not supplying a TT installation.
