which raises a point. resin filled underground SWA joint kits. they come including screw terminal connectors and screw clamps for the braid that provides continuity for the armour. obviously, once the resin has gon in, set, and the joint is buried, how can they be deemed as accessible? comments in a sealed brown envelope with plenty of £20 notes for padding.
Can't answer that one really. Don't some of these joint kits use shear bolts? Also i guess the resin (if properly filled) may aid in stopping the screws from loosening?
