New Consumer Unit ?

[PBC_1966]

a consumer unit has a main double pole isolator and then an arrangement to permit multiple lower current circuits to be safely connected to the incoming supply. I'm not sure if a single breaker enclosure is similar enough- there's no provision for multiple lower current circuits and no distribution going on.

The definition of CU states "one or more fuses, MCBs etc".

So would that make a switched FCU a "similar switchgear assembly" then?

 

[RF Lighting]

No.

What do you mean by

an 8 way single RCD Consumer Unit with a plastic casing.

?
Is the RCD the main switch or is it a split load board (i.e. there is a main switch and the RCD only controls things such as sockets)?

 

[Iggifer]

I would include everything you'd normally refer to as switchgear under amd3. Certainly any form of consumer unit, definitely switch fuses, and I suppose, if you were going to fit one, not the supplier/DNO a 2P/4P isolator.

There's plenty of metal switch fuses about, and I think Wylex even make a metal REC2S now if I'm not mistaken

Can't find any, but that does not mean they are not around.

Incidentally, RS have a good price on the plastic REC2S, £11 instead of nigh-on £30.00

Yes, that is the cheapest price I have seen, the average price is around twenty-five to thirty pounds at the so-called rip-off merchants.

 

[Iggifer]

Maybe I imagined it!


Oooops. Mentioned Wylex

No.

So how does one determine whether an assembly consisting of a double-pole isolating switch and a single fuse is "a similar switchgear assembly" or not?

 

[EFLImpudence]

You don't have to; according to the definitions it is a consumer unit.

 

[EFLImpudence]

I suppose it's not a particular type of distribution board - so it's not.

 

[ban-all-sheds]

So what about one these:

Are they "similar switchgear assemblies"?

 

[Iggifer]

I would class a switchfuse "similar switchgear assemblies" yes.

Whether the IET do is another matter, but I would have thought so

 

[PBC_1966]

You don't have to; according to the definitions it is a consumer unit.

Which definition?

 

[EFLImpudence]

Part 2 in the BYB - although I did change my mind as it starts with "a particular type of distribution board".

 

[PBC_1966]

So what is the the full current definition in the book?
