Notches or Holes, clip or not to clip?

Don't forget 'proper' notch cover plates are available, eg: 52mm x 73mm Safeplate - Protect Pipes & Cables - https://www.tlc-direct.co.uk/Products/TLSP1.html?source=adwords&ad_position=1o1&ad_id=45425533757&placement=&kw=&network=g&matchtype=&ad_type=pla&product_id=TLSP1&product_partition_id=174047055187&test=finalurl_v2&gclid=EAIaIQobChMI_b6gu5Hu2AIVUrbACh20nwzMEAQYASABEgIrD_D_BwE

Wow thanks for this link. This has changed my life.......

I used to use Metal UV box lids

in answer to posts#39 and #40.

the plates should not be earthed as they are not exposed conductive parts of the installation. they are just metal plates with cables sitting on them.

nor should the y be bonded, pete, as they are not extraneous.

Tel, I was trying to be sarcastic, obviously didn't work, did it? I agree with what you are saying. Just trying to point out what a ridiculous statement it was in the first place, next you will have to earth the screws and nails that are used to fix the floorboards, stupidity at it's best, earth the plates my arse.

Generator - do you also earth (bond) radiators and metal windows????

 

[telectrix]

and don't forget sink tops and metal garage doors

and bond all the floorboard nails.........

I'll ignore the sarcasm Pete (seen far worse on here! ). I was thinking about the similarity to metal capping, which I think is now supposed to be earthed ( certainly in 522.6.6 outside of a 'zone' ). Earthing of concealed metallic cable covering is only common sense in a house - regs or not. Everything has to be hidden - even sockets.

I've had experience of this in my existing house AND the previous one! I got a good belt when I touched the end of a wall capping under the floorboards - good job I didn't have the other hand on the CH pipes! Turned out the Dado Rail in the room below was nailed exactly over the capped ring main cables, vertically above a socket! - I was wondering why that circuit had a lowish IR! - 5Mohm.
In the previous house the wall in the hall had a faint 'rough ' feeling in the area above a socket - that circuit also had a 'lowish' IR , guess what? - nail through the capping, fixing the Dado Rail!
In both cases the capping can remain live for years - and it wouldn't trip an RCD either. If the capping is earthed, a penetrating nail/screw/drill would trip an MCB if it touched a live, or at least an RCD (hopefully).

So, hence my comment about the protection plate - which wouldn't be required if the joist were to be drilled! - and no, I wouldn't earth radiators (which are connected to earthed pipework), nails, screws,
or metallic windows ( unless they are motorised).

Better keep my head down now!

I have bonding to my cutlery drawer, so none of my forks are risky when i chuck them in randomly...but, I'm puzzled about diversity...does the number of adjoining knives and spoons affect the situation were I to accidentally switch the whole drawer on at once, given the lighting in said drawer is tee'd off the cooker-hood...and the drawer slides are only on a 6mm cpc?

and on a serious note, in my last house I removed an old carpet in a bedroom and saw a slightly raised nail-head...it was live... and had been for years probably...neatly placed into a cable supplying the nearest socket...it was my daughters bedroom, and she was 1 at the time, crawling around on all-fours..
naturally, not being a spark, I put a thicker carpet down!
