Discuss Do plugs have to be fire rated? in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
Ah didn't think so. Thanks for the info.It's not a thing, according to Electrical Safety First website q&a section.
I'd also argue in the vid i saw, that once strut is fixed to the wall it becomes part of 'fabric of the building' and the fixings securing the CU to the strut being metal means it's fire rated.
Yes, its all about time and exposure. A plastic Rawl plug will fail once the metal screw has heated up enough to soften the plastic plug to an extent where it easily pulls out but in most situations the building is likely to have been vacated by all by the time this happens.The diference can be demonstrated by holding a blowtorch flame against a plastic cable tie holding something to a metal frame,
then repeat the experiment for the same item being held by a screw into a brick with a plastic plug.
it will take a long time to heat the brick to the point where the screw pulls out of the brick.
In a fierce fire, everything will fail, steel, brick, "fire rated downlights", plasterboard, it will all be destroyed. The key term to remember is "premature"
