Hi all, I have done a few EICR's before however could do with a bit of advice on what codes you more experienced guys would give these observations;
1 Old 3036 DB made up of wooden base/back. (C3?)
2 Underszed main bond. (C3?)
3 Cooker switch mounted 18" above cooker (C3?)
4 Mutiple cct's in MCB (C3?)
Thanks for any input.

The definition of "final circuit" mentions "circuit" so the definition of circuit needs to be referred to. Which is also covered by 314.4

There are 2 separate definitions in the BYB. one for 'circuit' and one for 'final circuit'.

Then you need to re-calibrate your brain.

Multiple radials from one OCPD are classed as one circuit which is spurred at the OCPD.
Dividing these branches into separate OCPDs would make them individual circuits.
This is by definition, and cannot be anything else.

he is a lost cause andy, he wouldnt understand parallel supplies either.

a parallel supply is exactly the same so no code.

besides smokes would be looped off perm L from a light not back to board

Come on we can disagree.

 

[Andy78]

Nope. We are gonna have to agree to disagree on this one.

Does the definition for final circuit mention an OCPD ? No
Does the definition of either final circuit or circuit mention standard arrangements or your preconceived ideas of what a circuit should be ? No
If a radial was spurred off into three branches along it's length would you say it was separate final circuits ? No
So when it is spurred at the OCPD is suddenly becomes more circuits ? No
Is the definition of circuit an arrangement in any form, not just standard final circuit arrangements, supplied by the same OCPD ? Yes

It's not agreeing to disagree, it's just your failure to read and understand definitions.

I fail to see how hard this is to comprehend?!

Let me make this simple for you UKES; that regulation is there to prevent people from connecting one circuit to two OCPDs.

No matter how many conductors there are in one OCPD, it is still one circuit. Take a branch from that one circuit and connect it into a second OCPD and you would then be in breach of this regulation.

fair enough.

if one cable went to an ashly box in the loft then had 8 cables off it feeding different lights, would that be classed as one or more circuits?

its in 8 differenet rooms

So in your opinion when would 314.1 come into force?

At the design stage.
You wouldn't put everything onto one ocpd so the installation is divided into circuits. Lighting,power heating etc.
Similarly, an installation with say several rooms or floors or high loads wouldn't have all the power on one circuit. That's where reg 314.1 comes in.
How these circuits are arranged or divided up is down to the person designing the installation.
Now, if for example he puts several rooms onto one way of a db then that is one circuit.

So when does a final circuit start / finish?

 

[Plonker 3]

Can just see the test sheets now

Circuit 1 lights ground floor
Circuit 1 door bell
Circuit 1 smoke detectors
Circuit 2 RFC ground floor
Circuit 2 Socket below DB
Circuit 2 Boiler

You can have mine instead if you like.

 

[Guest125]

I am starting to come around to what you are saying gents. It must be the eliquent way in which you put it. Do I agree? Probably not. No big thing. If carry on doing things how I have been taught it still is not wrong is it?

 

[Andy78]

So when does a final circuit start / finish?

I'm out..... I refuse to believe you are not on a wind up with this one now.

 

[Engineer54]

So when does a final circuit start / finish?

The circuit branches (they are not separate circuits) would all start at the terminals of the OCPD and finish at the last light position or socket outlet fed from that branch...

How by definition, can a single OCPD supply more than a single circuit??

Easy!
