Is there a sure-fire way of knowing if a SWA is PVC or XPLE if you can only access the 'tails' inside a DB ?
xple normally has a 'waxier' feel but harder than pvc

You could measure over the insulation of the cores & OD of the incoming sheath, they are different between the PVC & the XLPE versions.
Unfortunately the sizes are in the BS which is stupidly expensive, though, if you can see the manufacturers name on the outer sheath then you could check their data.

AFAIA most of SWA is XPLE now days,,, however I always calc for PVC as I can't guarantee that the terminations will be rated for the higher temperature......
Is it OK?I have no access to the SWA except in the DB .
My local independant always supplies PVC unless XPLE is specifically mentioned .
I have inspected a job (awful work) done only 5 months ago by a NICEIC contractor. One of the many things is a 6mm, 3c swa buried for about 18m with a 40A , B type breaker. If its XPLE its ok.
