Hi all. I'm planning to upgrade the wiring in the garage but, before going any further, want to identify the incoming cable to check its capacity etc.
Garage is about 6 metres from the house, built and wired some 25-30 years ago. The cable (buried) is twin core and shrouded in a semi-rigid orange sleeve (aluminium?) which also acts as earth.
The two current-carrying wires are both black and are factory printed all along with what looks like "STUB SLV 7 & 7.5mm2". The printing is not clear. Those 7's could be 1's but the wire is far too chunky to be 1 or 1.5mm. What's all that about?
I've Googled like crazy and can't see any reference to this product. Can anyone help? Also, how is earth-shielded cable viewed these days?
