Fire rated clips - any suggestions?

[Mark Goddard]

Hi. Could anyone advise on the types of fixings / clips they are using to comply with: Wiring systems shall be supported such that they will not be liable to premature collapse in the event of a fire’ (clause 521.10.202). If, for example, there were a couple of runs of twin and earth above an escape route then what method of fixings would now be suitable. Thanks

Metal cleats/P clips/ steel saddles. For example PVC conduit should now be secured with steel saddles. Various proprietary clips are now available from wholesalers to fix inside plastic trunking and secure cables within.

As above and and metel tie wraps, but prefer the former.

Screwfix seem to be showing packs of fire-rated twin & earth clips, except they don't actually have any to buy yet:

Not seen those before, you would of course only need to use them at intervals sufficient to support the cable, plastic clips could still be used in conjunction with the above.

Thanks all. Hadn’t seen the screwfix ones either. Appreciate your help

I've just ordered a load of these to try out.

Cheaper than the Linian clips, though... my wholesaler is quoting £30+VAT per 100

should go the whole hog and insist on MICC secured with copper p clips. bugger off this horrible T/E.

1 - 2.5mm that's quite a wide range for those Schneider clips. I hope they aren't stupidly oversized for 1.0mm cable.

Let us know how you get on with them.

Saren stuff simple and effective, excellent customer service too. I like how they allow a nice neat installation, and you can screw them in, instead of hammering, which is brilliant where the boards you are fixing to are not well supported.

 

[freddo]

They are especially neat where more than one cable needs to be fixed.

So has anyone actually confirmed that plasterboard isn’t suitable protection?

At least 30 minutes according to one manufacturer: What is the fire resistance performance of Gyproc plasterboard - https://www.british-gypsum.com/technical-advice/faqs/050-what-is-the-fire-resistance-performance-of-gyproc-plasterboard

I'd say that's suitable.

The wording of the regs is 'to prevent premature collapse'
Typically vague!
My view is that this reg is only aimed at surface mounted wiring, and that wiring enclosed by other building elements such as plasterboard are not affected by this. Seems to be the way that the amd3 rule for escape routes was applied.
I think it is fair to say that if another building element has to come down before the wiring, then the wiring hasnt collapsed prematurely.
