Yes, I know you are saying what some other people believe.
However, what I am saying is that -
if people believe a double socket must not be loaded with two 13A loads because the socket is only rated for 20A then to prevent two 13A loads being connected by Mr.Public it must follow that the socket should be protected by a 20A OPD.
I do not recollect this having been mentioned by anyone nor stated anywhere before, therefore double sockets must be manufactured to work with 26A of load (as would the 20A switch). Why double sockets are said to be tested only to 20A, I have no idea.
That some double sockets (and plugs) overheat is presumably just because nothing lasts forever.
