8 way CU with 17 circuits

[wozz]

I think I have missed making my point after an argument (friendly) his view was that every circuit should have its own way and did point this out
the point I was trying to make was there3 is something in the regs regarding this
(I will look it up)

I think you may struggle to find something in 7671 regarding this.

It goes along the lines of "every circuit should be installed to minimise inconvenience in the event of a fault", read into that what you want, but there is nothing wrong with putting more than one circuit into one device as long as this requirement is met. from memory it is probably in part 5 of the BGB, but i don't have the inclination to go and have a look.

sounds like a very very wooley (sp?) reg there howard.

Possibly the line and neutral conductors of each final circuit shall be separate from all other final circuits.


However multiple conductors in one device just means it is a single circuit with multiple conductors.

yes, nothing wrong with it, bad design etc etc etc but can't fail it

 

[Engineer54]

Nothing wrong spurring off a ring circuit at the MCB/RCBO providing all the usual conditions are met. It tends to be lighting circuits/arrangements where you will see more than one conductor is found leaving the protective device, and more often than not in a domestic installation, that second conductor will be to provide a supply for a ELV doorbell transformer...

In many or most cases, yes it would be considered bad practice, but not in all cases!!
