Zip ties on tray worked fixed to a wall

[keiren]

Come across a new install with tray work fixed across a wall above a door way with plastic zipe ties is the a regulation that states metal zip ties should be in situe ?

I had to re-tie 100s of metres of overhead cables on a ship once with metal ties because of in a fire there'd be burning cables flapping about everywhere.
So, above a doorway, I'd do the same.
No idea what, if any, the reg number is.

I could not seem to find nothing i think its better to play it safe when cables can fall and cause a hazzard / Death

Would be installation method.

No regs as far as I’m concerned. Common sense prevails, fire proof restraints every time. I can’t see why the question should arise.

 

[telectrix]

fire proof restraints, eh. like it.

No reg, if there were a problem with plastic ty wraps they would not sell them. You may be confusing fire alarm installs where cables need to be secured by metal p clips or metal ty wraps, certainely no issue with plastic ty wraps on normal circuits.

No regs as yet. The proposals for the next ammendment make mention of fire resistant fixings for escape routes though.

Dunno about that, plastic tie wraps are not specifically made/produced or sold for use in electrical installations. I've seen them used in totally the wrong circumstances as far as securing cables to cable tray and the like!! People seem to treat those plastic tie wraps as a suitable replacement for clipping and cleating for just about every situation. Let's hope they don't tie wrap cables that could be subject to 20+ KA.... They will find, to their cost, that they don't, but spectacularly!! lol!!


But i suppose for general purposes, the use of ties is fine, ...but i still prefer to see bare or plastic coated perforated metal strip used in general terms, and substantial cable clamps/cleating as and when necessary...

I couldn't agree more with you ENG, however they are perfectly acceptable to use, it is up to the user to decide via design whether they are suitable for use on the Jobs they install, nothing wrong with them in reality, however they should be avoided on some projects as you mentioned of course.

Had this argument before with a project engineer over fire alarm cables during a fire. I asked him what about the plastic wall plugs holding the P clips in during the fire much to my amusement lol.

Is the op not pointing out that the tray itself was fixed with ties, not the cables?

LOL, it makes me laugh the fact sounders are made of plastic and yet the cables going to them has to be fire proof, I would like to see fireproof sounders myself and fireproof bells, still thats another debate for a different forum I suppose.

This has always been a debate, as detection being plastic is ok, as once activated it has no further use. Bs argument is plastic siren sould be mounted on galv through boxes to keep integrity. (imo very open for debate).........Plastic cable ties, common sense here, if cable is lying on tray...plastic is fine, if cable is being held up on tray, steel ties every 3rd of a meter.
