Discuss supporting cable above a grid ceiling in the UK Electrical Forum area at ElectriciansForums.net
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 afterwarddevil'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
al those i've come across are steel.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.
