presumably because above ceilings and below floors, the cables have been installed deep enough to not be subject to nail or screw penetration.

Have the same options as for cables concealed in walls, except for RCD protection.
Depth greater than 50mm, cable with earthed screen, earthed trunking or conduit and mechanical protection.

You are more likely to nail a cable in the wall through hanging objects on said walls, than damaging cables which should be installed deep enough through and above the ceiling

Of course, no one has ever just notched the top of a joist to run cables, or used an existing notch for pipework.
All joists and battens are greater than 100mm, no one’s ever laid a wooden floor on a concrete slab, or fixed new plasterboard over existing lath and plaster using 1” battens.

One site I was involved with back in the 70s the flats had a concrete slab, with roofing battonslaid, not fixed then normal floor boards fitted normally, wiring laid in the voids between the battons, I didn't stay long on that site, decided that sort of botch was not for me.

I wondered why it has been so quite on the forum recently. Seems most have been here, arguing amongst each other. Bet the OP never wished he'd asked

So what is the answer to his question?
