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.
