Circuit for 2 lamps, PIR and override - is this notifiable?

[RockySundae]

Hi all, as per title and attached PDF I am looking to clarify a few things with my proposed circuit.
The aim is to have a PIR unit that can be turned on or off, and two lamps that can be indepdently switched between live, or onto the switched live output from the PIR.

When we moved in, the original install was a T&E cable going through the wall from a 2 gang box to an external IP67 JB.
As I am changing this to a 4 gang box (metal faceplate, centre off switches) with a 7 core H07RNF cable, and two short external runs of 3 core H07RNF cable (elevated and attached to brickwork) to either lamp... does this consitute notifiable work under part P regs?

Also if anyone could clarify...
Are suitably rated WAGO connectors in the backbox/JB acceptable for this purpose?
The diagram is coloured according to proposed sleeve colours (all black cores in the H07RNF) - Is there anywhere I could change some of the brown sleeving to e.g. Red to make it more intuitive?

TIA

Well for a start your country is listed with a Union Flag so it does not tell us which Country you are in.
England and Wales have different versions of Part P and Scotland has something Else instead of Part P = the three make up the Nation.
Northern Ireland has something different I think and if you add that to the British Nation then it becomes the UK.
Is the UK also a nation or is it properly called something else? I have no idea.

If you want to know what you "should do" then we need to know in which country, if you want to know what most would probably recommend then I will not mention that.

If you want to know, technically, how to achieve circuit changes I could answer that.

No, they do not.

 

[ebee]

No, they do not.

I stand corrected - they have a different version of what is notifiable and what is not.
Good work that man - I did wonder which one of you would spot that deliberate mistake

I would think someone with access to an electronics workbench would know what they are doing. So I would not really worry, unless you're doing up to sell. Or it is rented.

i was not aware of that

Electronics workbench was the CAD tool used in university, it is expensive, so would expect anyone with access to it would be reasonably clued-up.

Apologies, this is pertaining to the rules in England

Im confident that it is safe in theory but tend to do industrial work such as automation and panels, so just wanted to check I wasn't about to breach any big no-no's in domestic regs, E.g: I am using a 1.5mm2 7 core cable derated to 50% (~10A max), then going into 2x 3 core 1mm2. It's all protected by a 6A mcb (and 30mA RCCB) which means in theory it is safe, but I have heard that domestic regs suggest that all cable in the circuit should be of the same size, regardless of whether the lowest capacity point in the circuit is still suitably protected?

- Not selling any time soon, but would like to avoid this being a pain point when it does come to that time

Nope. People hear all sorts of nonsense.

Yes, dark suckers for example problem is I can never keep a straight face.

Everybody loves an Encabulator

Being used to all black wires with physical tags to denote the wires function, I presume the colours as per my schematic are correct, but that ends up being a lot of brown sleeving in the boxes - any way I can reduce confusion on this by using alternative colours such as red/grey?

You may (are allowed to) use physical tags.

Huh... TIL, never seen it in a domestic setting, is there a widely-recognised/general convention as to the actual content of the label? E.g. '230v' or 'L' for the live?

I did see table 51 whilst trying to research this, but footnote 1 suggests a lighting circuit is considered as AC power and not Control circuit?

The note doesn't mention 'control circuit' - but what else would control such things?
