Thats what the regs state, but I haven't seen any manufacturer going with anything other than metal. Unless you know different?wrong reg states not readily combustable so unless you coat the plastic in parafin it complies

i cant remember manufacturer but at least one are saying there plastic boards comply with amd3
how so the un standard for non readily combustible is a lower temp than the old glow wire test
But not readily combustible is NOT what the Requirement is - "non-combustible" is.
metal can be set on fire thoughWhat they should had specified in BS 7671 is "metal"
Pratts!
metal can be set on fire though
Wire wool, lithium in water. But most manufacturers are using mild steel.metal can be set on fire though
Everything can given sufficient heat!metal can be set on fire though
I'm not a scientist, but I think that when metal is heated to a sufficient temperature it changes from a solid state to a molten state. If it's heated to a higher temperature it may actually boil and turn into a gas. To catch fire, is a state of combustion. If metal can be combustible, then it's not gonna be much use as a material for 421.1.201.Everything can given sufficient heat!
exactly and certain types of plastic easily pass the new regs.Everything can given sufficient heat!
the british standard on the definition of non combustable materials can easily be met
I've used a few of these to supply submains etc & I agree top value and a decent quality unit,but I've been thinking...what about amendment 3? they don't comply eh?
i cant remember the correct wording and my regs book is on the shelf and when i posted that i was 80miles away from itBut you must remember that "non-combustible" and "not readily combustible" are not synonymous.
Eye, years ago though they did make it to 25mm2.T&E only goes up to 16mm with a 6mm cpc.
