Swa through scaffold

[ThrownRazor25]

My work is erecting a scaffold as part of rough cast project.There is a SWA on the house which is enclosed in steel capping.

Does the scaffold require to be earthed as under fault conditions the scaffold would become live?

It might be a concentric cable so my understanding of this is that if the cable was to be damaged then the earthing of the cable would be too therfore creating an earth path similiar to SWA so would the protective device not operate under ADS anyway?

Or because it is an extraneous conductive part should the scaffold be earthed regardless.

Seems resasonably specialist if there is a guidance note for scaff as above ^^

But I always ask myself 2 questions. Is it extraneous or part of the electrical installation. If yes to either it's required.

But I'm confused, is it in the scaffold or capping on the building?

The Autumn 2016 Connections magazine has a piece on 'Scaffolding - is bonding required?'

Thought thumbnails would be more discreet, suppose I didn't triple post this time!

Yeah, but it's a least a third as interesting.
