supporting cable above a grid ceiling

[TJC1]

How do people support cables above a grid ceiling?

Currently pricing a shop fit and need a quick easy way to support cables above the ceiling.

Basket? Metal wire wire metal ties? Metal ring plates?

I see something in PE magazine when there requirements for metal cable supports come in and was written by the NICEIC I believe. It said about catenary wire from one side to the other and metal cable ties. I couldn’t help think it was a bit of a bodge TBH.... Saying that though most cables above suspended ceilings look like they’ve been thrown in using a javelin so it might be an improvement on that

Tie wrap to literally anything that looks remotely secure

Well that’s what nearly everyone else does when you poke your head above a drop false ceiling

It really does depend on the amount of cables and the type of wiring you will be installing.

What will you be installing?

A loop of all round band...?

A basket system would seem the best option, with perhaps tray around perimeter walls, although it's rare to see anything other than improvised loops and straps in use.

Shop fitting wasn't really my bag , but have done a bit a few years ago and always tried to get at least a but of 4 inch tray around the perimeter or the unit. Then sort or shot off the tray to the lights etc

Cheap and quick, basket around 2m in from the parameter all the way around. Supported with gripple wire on those cheap 90o bent brackets. I’ve seen them called mending plates but don’t know the correct them for them. It’s a bit wobbly but seems to be the most common way I have seen. Good luck

Basket or all round band

devil's advocate... laid on the grid, cables are supported, and the grid is metal . all well and good on a new install, but how to install tray or basket when false ceiling is existing.so ........ tin hat on

Take out 2 tiles and a short bar usually is enough to get 3m lengths in. Depends on the void tho. I have before thought why not being on the grid if it was earthed but I felt too dirty afterward

Grid support is usually aluminium I believe. If so it has a lower melting point than steel therefore in a fire it can deform and give way , allowing any cables that are resting on top to prematurely collapse becoming an entanglement danger.

al those i've come across are steel.

last encounter i had was using a pry bar to get 30 600 x600 LED panels in. think there were 3 that actually went in by hand. this grid was deffo steel.
