but if the wiring to the light came in 12V and the 'switch' was also involving some box of electronics providing bell-transformer like insulation then bell wire might be correct. (as indeed some elv LED drivers almost do) I should hasten to add I fully agree the mains wiring to mains lamp from a mains dimmer should be mains rated cable, but it is quite hard to draft a regulation that correctly covers both cases. And does not encourage folk to ask for a Zs test at the lampholder.
