The use of 'nail-plates' as Paul suggests is fine. The regs state that there should be 50mm from unarmoured cable to the face of the floor/ceiling, or mechanical protection provided. They also state that the requirements of such protection "are difficult to meet". However, the illustrated plates suffice.

In walls, however, they state " Where a cable is concealed in a wall or partition at a depth less than 50mm...it must be enclosed in an earthed metal conduit (trunking or ducting) or installed [using the 150mm rule]..."522-06-06 If the cable is passing in the 150mm zone there is no requirement for protection.

This is a 150mm wide strip ( or the width of an accessory if greater ) that runs vertically above and below the acc'y, and strip below the ceiling height and on the internal corners of rooms. Also it extends left to right of accessories - but NOT diagonals. It should be remembered that this rule extends also to the BACK of the wall in certain circumstances.

If in doubt, plate or conduit it! [Linked Image]

If hindsight were foresight, we'd all be millionaires!
