Unknown Cable.

I bought and installed, what I thought was a brand new, a roll of 2.5mmm2 T&E AEI cable back in 1986-7. When tested there was a short between Neutral and CPC. which was situated half way down a plastered wall in a kitchen.

You never know what the condition of the cable is even when its sold as new from a trade counter. I would always recommend a trade account and deal with suppliers that you have established a trustung relationship.

Installing non standard 'European' cabling without knowing its provenance is pushing the risk factor out a little further.

IMO

1. Do not use

2. If you can't resist the excitement then

3. Low reading ohms test, adjust for length, ambient temperature. compare values with known milli-Ohms/m for correct csa and copper content

4. Insulation Resistance test, perhaps something a little higher such as a flash test.

Alternatively.... Pass to apprentice to strip the sheathing and insulation off and place in the scrap bin for recycling.
