I wonder if you can help me? I have a socket that is halfway up the
wall and I would like to lower it to a more sensible level. The wires
to this socket are run in the metal capping you describe. I am
concerned because both wires are run together and having read the
above post it sounds as though the cables are rated at 19.5A "below
what is necessary for a ring".

You're worrying too much. Rings are always installed as yours is.
