Didn't know you could get single core SWA. You'd think there can't be many uses for it.
Of course you can, it just has aluminium armour instead of steel for obvious reasons.
The use of single core steel SWA is not permitted under 7671.
Confusion comes in due to the two definitions for SWA. It's either steel wire armour or single wire armour.
