OSG 7.3.2 cables in walls and partitions

In the above,item d states the cables can be protected by earthed steel conduit or,

Item e then states :mechanical protection sufficient to prevent penetration of nails,etc,

but no mention of earthing..

I have a situation with a short 200mm horizontal run outside the zones.

I could slide a lenght of earthed conduit over,but then the earth connection would be plastered

over and could not be inspected.

If I treat the conduit as mechanical protection,it would not need earthing?

Wondered what others would do.

Regards,Hz

So do we just connect the C.P.C. to an earth terminal as usual? Or do we have to gland the cylindrical foil in any special way?

Just sleeve and terminate the c.p.c. - as you would for T&E. No glands required (although normal round glands can be useful where an improved IP rating is needed). The foil is in contact with the c.p.c. all along the cable, so connection to the foil is automatic.
