Not sure what your qualifications are but your comment “In the UK fridges and freezers are not wired through the RCD to prevent this problem.” is just not true. All sockets need to be protected with a RCD in the UK.
Hi Pedro. If you have a split service distribution board which has two RCDs it will be wired such that the lighting, alarms and things like freezers will not be lost if one RCD should trip.. This was the reason why split boards came about as well as the fact that it is safer. So the household sockets are on one RCD and 'fixed' items on another.
As I have indicated the last thing you need is your freezer thawing out if you are away. In Spain you would be left in the dark and you would probably have to scrap the freezer when you come back. They have not got round to split boards yet.
For you information I am electrical and mechanical engineer and I have done countless installations using split boards.
If you look at the attached picture you will see the main switch on the left two RCDs and four breakers for each. So you wire them in such a way that you are not left in the dark should something trip your socket's RCD.
