Is there any reason a circuit fed in t&e, protected by an RCBO,  can not be clipped to a accessible surface feeding a socket

    If you wanted a fridge, that keeps tripping an RCD… on a separate fuse then surely, you'd have the cables visible so as to use a fuse not covered by an RCD?

    Not necessarily - you could use cable with a concentric c.p.c. (BS 8436, SWA or MICC) or steel conduit and still have it concealed.

    Yes folks, but the fridge would have to be hard-wired and not on a plug; or not at home and with a documented risk assessment.

    or on a 63A bs6363 plug - so a plug so ill suited to removal as to be hard wired to all intents and purposes….

    Yup a plug conforming to the “Specification for welded cold formed steel structural hollow sections” probably is hard to unplug ;-)

    Even a BS 4343 one (now properly called BS EN 60309) would be a bit dodgy in a domestic - as they're unshuttered.

    T&E is a PVC insulated and sheathed cable (or, these days, if you pay a bit more, an equivalent material to PVC that has no halogens, or has some fire resistance)

    H05VV-F (general domestic appliance flex) is a PVC insulated and sheathed cable.

    The sheath provides mechanical protection to the insulated conductors.

    It's OK to use a PVC insulated and sheathed appliance flex (H05VV-F) on a lawnmower, although obviously the manufacturer would recommend an RCD.

    There are situations where, obviously, we'd want more mechanical protection for a sheathed and insulated cable, but I think this short introduction to the uses of PVC sheathed cables helps in the “general case”.
