I often think the "protection" issue is a load of ********.
After all, the only protection that would actually protect would be
steel conduit.
All this plastic/thin metal tacky stuff won't protect against an
electric drill.

The regs do define the level of protection.

But you have to remember that as long as the "thin tacky stuff" is properly
earthed, it *will* provide protection as the fuse will blow/breaker trip
with the touch voltage on the tool you banged through the cable not
exceeding 50V for 40mS (IIRC).
