Flexishield cable

Does anyone know if the aluminium sheath is earthed. The way the manufacturers talk it negates the need to protect circuits by RCD but as the sheath is not earthed and can be penetrated by a nail or screw, i can't really see the benefit of the stuff other than for interference.

I guess its quite expensive too.

On my current project in central London, 275 very expensive apartments are being cabled in fp200. I assume the designer has a reason for this. Note that my company are not installing this, we are purely data and AV on this project.
I will check out a CU for RCD protection when I get a chance

It was the 17th that brought the requirement of cables 50mm deep

My bad too many ammendments and regs since my days ...its all just a blur ..

Excuse me, my response was in regards to whether SWA could be penetrated by a nail or not.

Its surprisingly easy to put a screw through SWA. The screw will just slip through the steel strands.
