With so many low-voltage devices now powered from plug-top power supplies (the ones where the power supply and three-pin mains plug are one unit) there is sometimes a need to use these in permanent installations. For example lights - like the ones used to decorate the plinths of kitchen units or stairways - are often supplied with this type of electrical transformer. What is the correct way of making a permanent installation of this type of power supply? You need a mains socket but often, if it is for lighting, it would need to be wired into the lighting circuit and not the ringmain. So you do not want anyone mistakenly using this as a general socket. If it is hidden away that reduces the chances but is there more to it than that? Low voltage halogen lights would have transformers hidden in walls, ceiling voids or wherever to power the 12v lights. Is it right to add a socket into which the plug-top power supply is permanently connected in a hidden location (like in a wall or ceiling void) and connected to the lighting circuit? Do you need to add a warning label or somehow permanently couple the plug and socket? What are the rules or best practices?
