Plastic clips/cleats

whjohnson
So, are plastic cable clips and cleats completed banned from use anywhere on an 18th ed installation now?

Do I have to chuck my stock away?

If still permissible to use, then where and when?

If not, how would one go about securing a run of NYY to a light fitting on the corner of a beautiful stone detached house without resorting to the use of steel conduit, galv cable tray secured with resin or expansion anchors//SWA and steel ty-wraps which I'm sure the customer would be delighted with?


The proposed cable will run from an existing light fitting over the front door so I guess it is part of an escape route too.


What were they thinking of when they got together to come up with this nonsense?

I suppose plastic wall plugs are out too! If so, what are the alternatives?


Anyone out there with a definitive answer? Or are we moribund in a world of ifs and maybes?

    No, just where they'd be the sole form of support - clipping to the side of joists where a plasterboard ceiling will be fitted below would be fine, likewise clipping to walls where the cables will be plastered over. Similarly where the clips are only to keep things near rather than support the cables - e.g. clipping to the top of a batten across joists in a loft.


    For round cables, simple metal cored P clips seem to be the usual alternative (e.g. https://www.tlc-direct.co.uk/Products/FTWP32.html - other colours/sizes/brands are also available) - the general consensus seems to be that when screwed horizontally into wall (rather than vertically into a ceiling) plastic wall plugs are still sufficient.

    It's only a problem in places where if the supports failed and the cable fell it would then be an entangement or trip hazard. Clipped to a wall near  the bottom, or above ceiling joists, the plastic fittings are not a hazard.

    Metal P clips exist, and for the last word in cable support rubber cushioned metal clips   exist though are not cheap and  may be a bit overkill unless on-show.

    Plastic wall plugs do not seem to be an issue in walls, as the force is not in the pull out direction,  though the jury is out on some ceilings. Wall dog / concrete screws examples fit many places, as do the soft metal wall plugs. example of metal 'rawl plugs' 



    edit for your case of the NYY  black plastic dipped metal P clip  probably neatest solution, I'm hoping the price for one, is actually price per one box..

    Hmmm, looks like a lot of ifs buts and maybes then.

    Having looked at the price for those black P clips, I wonder if a roll of builder's band might be a cheaper method!

    Asked about P clips at wholesalers this morning - and no, they don't stock them other than for special orders involving the purchase of MICC cable.

    Some galvanised steel wire wrapped around a 6 inch nail at regular intervals should do the trick.

    Let's be sensible, please! If the exterior of a building has become so hot that plastic cleats, Rawlplugs, or WHY have melted, is any living person likely to be in the building?

    Oh I agree 100%, but you can bet your bottom dollar that future 'inspectors' doing EICRs will jump to fail anything remotely plastic with the head of a masonary nail protruding from it!

    I am still waiting for the old style metal 'buckle' clips to come back into favour. Those things never give up their grip on the cable!


    Might not find much favour these days tho with 'oh no, that takes two operations, and time is money' atmosphere many of us work under :(

    Buckle clips. I have no connection with the supplier at all.

    Depends where the fire starts - if in bins (or piles of rubbish) outside (perhaps ignited by a discarded cigarette from a passer by) the inside of the building might be perfectly habitable still - yet the fire exit (or entrance for fire fighters) might be past the seat of the fire.


    I recall an office where the concrete/steel stair well (the only means of escaping from the first floor) was condemned during a fire inspection because the waste paper recycling bin had been placed there.

    The metal clips that I think it was Zoomup that linked a while back are now available saw some on the counter in a local branch of CEF the other day.
