Or use Dewalt wall dogs and you don't need plugs.

Are there?? Have you got a link to one??? What a load of rubbish. As has already been said the heat sinking properties of a masonry wall into which a plastic plug has been fixed will keep it in place for well beyond the effects of smoke inhalation and spread of fire will have rendered life in such a building over.Wall dogs (good masonry screws) do the job very well and are a faster install than using any type of fixing.
There are reports that show the plastic wall plugs melting and the consumer unit falling from the wall well before the house is destroyed.
I'm sorry but I think this is just absolute nonsense. I do not accept that such a fixing would fail unless the building involved was an absolute blazing inferno. If you are seriously worried about this then I have no idea how you ever get to sleep at night?It all comes back to the responsibility of the installer should anything happen.
If in the future there was a fire and it was considered the CU had come away what then of the installer?
If you have installed in way that helped prevent that then not only are you covered but possibly you've help limit a danger.
Seems to me a simple step for little extra cost or time for maybe a very small additional bit of protection.
OK, well done, Carry on...I don't worry about it. Its an easy thing to not worry about. Just fix with a non plastic fitting.
Oh for goodness sake this is ridiculous. The document is referring to cable systems in mostly non-domestic situations where fire fighters have been trapped by cables collapsing into fire escape routes, not domestic CU's falling off the wall!!Fire performance of cable supports - IET Electrical - http://electrical.------.org/wiring-matters/58/bre-report/index.cfm
@Nickj here's the document you referred to and its fire 2 results that links the collapse to the wall plugs melting after approximately 20 minutes.
I agree with @Pat H that for the added little expense and no real extra time actually carrying out the work than the conventional method warrants it if you don't mind going above and beyond what's required.
NoWhat is it about a straightforward task like fitting a metal CU that causes soo.. many problems, is it just me.
Yeah I was just pointing out the document which refers to the premature collapse due to wall plugs, so they might not be as robust in the event of a fire as you think.Oh for goodness sake this is ridiculous. The document is referring to cable systems in mostly non-domestic situations where fire fighters have been trapped by cables collapsing into fire escape routes, not domestic CU's falling off the wall!!
Don't worry about the IR values, continuity, CPC's in lighting circuits, Earthing, Bonding, labelling, discrimination, accessibility, neatness or other quality of workmanship, or all that nasty paperwork and stuff, just make sure the bloody things rammed onto the wall with at least 4 coach bolts.Makes me want to weep.
No its not.What is it about a straightforward task like fitting a metal CU that causes soo.. many problems, is it just me.
Yes OKhttp://i.stack.Upload the image directly to the thread.com/ou9oP.jpg
No its not.
I think there is a certain amount of blindness and distraction in "being compliant" that results in the obvious being overlooked. Would any domestic scheme even examine the means of fixing a CU to a wall? I think not, hopefully they would be more interested in the installers competence at not electrocuting somebody or causing a fire hazard in the first place.
These are available, we use them regularly in fire alarm installations for cables passing through escape routes.Let me know if you find some metal rawl plugs
Eddy currents on a SP&N CU Get real
Next someone's gonna suggest metal MCB's.
