I want to run a 4mm cable from the loft to the garage, inside a duct which is currently used for plumbing. I propose to use 25mm flexible conduit, put it down the duct and secure it, then poke the cable down from the top.
How many saddles should I use for the conduit? Do I need a particular support for the weight of the cable at the top?
The drop is 8 or 9 metres.
