electric cables in concrete floor

[nottsrob184]

Hi all.
I am currently in the process of contsructing a concrete floor base for a rear house extension (new kitchen).
My wife wants an island unit that houses a dishwasher and electric hob.
Obviously i've got to get the sparks over to the island and i was thinking of burying the cable(s) in the concrete when i get it poured next week.
Is this OK? or will building inspector throw a wobbly?
I was going to protct the cable in a protective tube. If that is ok....what type of tube is correct to use for this.
Thanks for any advise.

Put them in flexible (electrical) conduit.

Get the gas fed thru as well, no point limiting your choice of hob.

You'll need electrics, gas water and waste services all putting in before the concrete base is laid. A good bit of forward planning will help.
You may also want to think about over island extraction, whilst planning the extension. Retro fitting can be very costly.

you'll need 10mm for the cooker and 2.5mm radial for the dishwasher..
best option if to set a couple of 25mm conduits into the floor and use radiused bends..
let the sparky put the cables in..

I've given the correct answer in your other post, but you obviously did'nt like it. Unfortunately you're being given some very bad advice by people that are guessing, especially joinerjohn.

It is illegal and highly dangerous to install gas pipes beneath structures.

And good luck with the damp problems.
