Support of cable to BS5839-1

[Galeon]

For all you older people , at least we dont need to worry about the wooden / fibre plug , now there is a thought ?

Well I did find the details on 300mm and 400mm, what my query was centered upon was the possible relaxation of these fixings distances as I have an electrical contractor who is arguing they can be relaxed if a risk assesment is carried out.

I since found an ECA circular that advises this relaxation is on drops to smoke detectors on cielings from the slab above, I have yet to find anything that says you can expand on 300mm on horizontal fixings though.

can't see how a risk assessment would be relevant to how a cable was supported to keep it functional during a fire.
sounds like contractor is looking for a way out.

I'd ask the contractor to produce the regulation that says it......
