Do "volt sticks" work on armoured cable?

[Bruce]

I have never (until now) heard of the outer conductor in a concentric cable being called armour. To my mind it is just a concentric conductor.

[The Natural Philosopher]

Wrong. They use steel armour. Copper is not an 'armour'

[ARW]

Yes. Point noted and I was wrong with what I said.

It was more to say to newshound (and other posters) that there are cables with copper not steel "outers" that look like SWA. The clue being in the use of the letters SWA.
