Fair enough.
I'd say it's just an isolation point and doesn't contain similar switch gear assembly's as a consumer unit would circuit breakers,fuses etc.
That's my take on it anyway.
Main switch in a CU, 60947-3. Main switch for one of those DNO things 60947-3.

It's the similar switch gear assembly I take as being the same not a switch on its own.
Would you code this in a eicr or note it maybes?
It's an interesting take on it as the DNO have their own regs as it where so just curious
 
If there's a risk of an internal non-protected factory cable link coming adrift within a CU and making the enclosure live then there has to be at least an equal risk of the meter tails escaping from the main incomer and causing the same problem ? So the only way to be sure of dealing with these scenarios safely is to have an external S type RCD, I'd happily fit that in an insulated enclosure. Although realistically with proper workmanship neither will ever happen- Ah therein may lie the problem ! :)
 
It's more to do with the internal wiring being single insulated and the risk of insulation damage rather than the wires falling out of the terminals.
 
I suppose the basic question is "is a switched fuse" considered the same as a fuse board?
I would say yes as it has similar switch gear i.e. A fuse with outgoing circuit ,main switch isolation double pole.
I would say yes as it has similar switch gear assemblies i.e. A fuse protecting an outgoing circuit and a double pole isolation mains switch
