Discuss Fire rated clips - any suggestions? in the Security Alarms, Door Entry and CCTV (Public) area at ElectriciansForums.net
Suspended ceilings rarely offer any level of fire protection unless they are certified and correctly constructed. Generally they are aesthetic with any fire protection above them in the void.And cables "slung" above suspended ceilings with little or no clipping....
BUT it would be useful if the BBB actually stated this!

I saw these on the website, have asked the local wholesalers what price they can give on them (Kew electrical and denmans) will post the prices i get.Screwfix seem to be showing packs of fire-rated twin & earth clips, except they don't actually have any to buy yet:

A standard plasterboard ceiling is 30min fire rating (from building regulations), this is considered by the "industry"as an acceptable duration.
This will be the advice that comes out from the "industry" bodies, all of them.
They will also agree and publish that plastic wall plugs are fine.
I don't know why it is taking so long for it to come out though!
sums it up nicely.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.
The duration of standard plasterboard varies dependant on source although I could be persuaded that the regulation does not include cables within the fabric of the building.
The plastic plug fixing is where I disagree and would be interested in your sources for such info.. The BRE have done extensive testing and published their conclusion which is the advice the IET and many other bodies tend to follow, their conclusion for plastic plugs is they are not suitable so I find it strange that this advice will be ignored when it is safety critical.
