TT With Amd 3 boards

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.

What is a non standard domestic install

A house that has its own marina?!

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?

Tin hat on.

Or possibly both

 

[Dave OCD]

Good point but there's no movement in there to cause abrasion and to damage the insulation on those links would require a high degree of idiocy.

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

If only the manufacturers would make sheathed links in the board this would be solved

Thought they said they would provide further clarification in the 18th. Think again. I might add a comment to the draft, big myself up.
