conduit

[rich22]

Hi i am putting a new double socket into a new stud wall.
I will be running the cable in 20mm round pvc conduit.
The question is do i run the conduit straight into the box through the hole.
Or do i have too put blind gromits before the cable enters the back box.
If so how do i support the conduit.

Why 20mm round and not oval, if use oval, the chase not as deep and can use some snap on clips that you plug and screw to wall.

Nice one Rockey .
So is the bush doing the same job as the blind gromit.

double sided tape and stick it to the inside of the plasterboard..

Yes it protects the cable from the sharp box edge ,as well as holding the conduit rigid and in place, makes wiring easier as you can push down and it will go straight in box first time.
Really for single core cables but can be used for T+E etc.

With T + E You can stop the pipe short and just use a grommet, depends really how you want to do it.

If you use oval, these are very good for joining the conduit to metal boxes:

I know they are meant for 20mm round conduit, but they are made of rubber and will deform at the top to take oval whilst the grommet-like bottom stays round to fit into the box knockout hole.
