OSG 7.3.2 cables in walls and partitions

hertzal123
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.

    Years back I was asked to lay some T & E on a trough on an old ceiling about 4" (100mm) thick. I insisted on a steel trough 4mm plate with screwd lid and earthed 6.0mm back to CU. The trough and lid wa a min of 1 1/2" (38mm) from joist tops and bottoms and  I was relatively happy with the safety of each (RCDd) circuit. Fingers crossed
