314.4.... irrelevant. The OP's circuit is perfectly safe.The Reg is 314.4.
You cannot comply with BS7671 by bunching circuits such as lighting or radials in the same OCPD. It is non compliant.
I've read the whole thread and I'm not understanding your argument.
I thought I’d put my input into this thread to rest but I had ten minutes to spare today and this was still bugging me. So I took the opportunity to call the NICEIC technical helpline about it. I have been resurrected!
Their view is that the regulation, although short on specific detail, as a re a lot of the regulations (as it is simetimes very hard to express the intended rule in writing), does in fact intend that each circuit should be connected to only one OCPD. In view of ‘what is classed as a circuit, I specifically asked about lumping circuits together with the view that they both become one circuit, and the view was that they don’t. The circuit is defined as per the wiring was intended and it should comply with BS7671. They would class this as a non compliance.
I asked, if in the event that I found this whilst doing an EICR, would I flag it and if so what would I flag it as. The view was that it should be recorded as a C3 for definite or a C2 if there was a danger of overload or other problems.

It’s an assebly of electrical equipment protected at it’s origin by an OCPD.A fridge in no way satisfies any definition of a circuit. It defines a piece of current using equipment fed by a circuit.
I fail to see why it poses an Electrical risk? Could you eleaborate on why?I presume you are talking about my posts. I am not shouting. I have explained my argument numerous times to the point of being immensely frustrated.
My argument has never been about whether lumping circuits together is safe; indeed I have admitted that I have done it, albeit for a temporary stop gap solution. It may well be electrically safe and in which case it can be done (temporarily).
If it is done as a new install it should be highlighted in the EIC as a non compliance and explained as to why it was done, along the lines of a justification. (By the way, the excuse of ‘I needed another spare way because I didn’t buy a big enough CU, and don’t think that the two I have looks to be enough for possibly future expansion’ is not a justification in my view).
If it is found during an EICR it should be highlighted as a C3 or a C2 if it proposes an electrical risk.
How much clearer can I be?
If you guys still don’t agree now then I can only assume that you have been practicing this. I haven’t so I’m not bothered by it.
I will now bow out! Live long and prosper!
True, only thing is you're using the bs7671 definition but that only applies to fixed wiring. Make it an fcu and I'll agreeIt’s an assebly of electrical equipment protected at it’s origin by an OCPD.
How does that differ from the definition of a circuit?
just to be an a**e they are... they are electronic circuitsBy your definition my electric razor is a circuit. And a gu10 lamp.
just to be an a**e they are... they are electronic circuits(assuming the GU10 is an LED)
Not my definition, and no, neither of those items.By your definition my electric razor is a circuit. And a gu10 lamp.
The definition of a circuit, makes no reference to fixed wiring.True, only thing is you're using the bs7671 definition but that only applies to fixed wiring. Make it an fcu and I'll agree![]()
Not my definition, and no, neither of those items.
A toaster perhaps, or a kettle.
Does your electric razor have a fused plug?So a toaster is a circuit but not an electric razor. I really don't get this definition of circuit you are using.
I’m glad that we have established that something that satisfies a definition in BS7671 is not necessarily the thing being defined.It's an appliance. It is current using equipment. Just like a table lamp or a fridge freezer, or anything that plugs into a 13A socket. It is NOT a circuit.
