Suspended Ceilings and the 17th Edition

[disinfo]

Hi,

Is there anything in the 17th about running cables within suspended ceilings? Specifically NOT laying cables over the top of ceiling tiles?

I've left my book at work so cant check.

Cheers

I wouldn't worry about the 17th on this one.

For years it has been accepted 'good professional practice' to support cables above false ceiling voids.

Reasons ??

1/ Ceiling designed to carry it's own weight, not electrical cable, BT, data etc
2/ Cables laid on the upper side of tiles prevents easy access, allows for different cable mediums to be in contact.
3/ Potential fire hazard when cables laid over light fittings


And the 'other' way, cable tieing to the ceiling hangers is wrong, the hangers are there to support the ceiling tiles and frame work, not a 16mm SWA

Cheers for that, I realise the point about good professional practice.

I am just ducked off because I have spent all day up ladders correcting someone else's mistakes.

My boss is trying (and failing) to get the perpetrators back in to correct it but the only answer he is getting is "it will be right, why are you worrying about it"

Theres catenary wires above the ceiling at my shop. Everythings fixed to them. Even double sockets for the cctv monitor on the ceiling and the sockets on the shelving gondolas (for magazine lights, freezers). The cash air tube guys even used them to fix their tube to. Plenty of weight on them.

Other stores I've seen 2" plastic pipe clips fixed to a plasterboard ceiling above.

Someone said the ceilings are only designed to support their own weight - what about those CCTV monitor enclosures - the plastic ones that are at an angle set into the ceiling?

I dont suppose there is anyway you could put a catenary wire in and tie the cables to that maybe Fittings in the cielings are generally set in tiles with a patress in them usually mdf the ame size as the tile

No, I'm having to use bow band it would be pretty much impossible to get a cat wire up there now.
