I would like to run an electric cable under a 4 inch insulated floor. The floor insulation is covered with 18mm t+g chipboard flooring. If I run the cable through a plastic tubing first, then under the insulation, can anyone see a problem with this. Beneath the 4 inch insulation is a concrete base. The idea is to put electric sockets at the opposite side of the room to were they are now. Many thanks. Neil

Should be ok. Remeber to de-rate the cable current carrying capacity due to its being burried in insulation.
Thanks John. Its only another socket for computer. Neil
If it's to a socket, it still needs to be derated in case something else is plugged in. This means that you may need to use heavier cable.
If you don't understand this, get someone in!
I have put the pipe in with a length of rope to pull cable through but will use electrician to make sure it is done correctly. Thanks to all for putting me right.
