Unearthed armour?

[Piratepete]

Spotted a couple of nasties on a solar PV installation yesterday.

1. Single insulated cables (4sqmm twin and earth stripped back) connected to the generation meter (obviously designed to take 25sqmm tails). Yuk!

2. They'd installed an SWA cable from the PV isolator to the isolator at the consumer unit without earthing the armour. It looks naff but as it's surface mounted and has an earth core. Does it need to be earthed?

Would you consider it an exposed conductive-part?
If yes, then it requires earthing.
If no then it doesn't.

That's a moot point! It's insulated, but I would've earthed it - just good practice.
