Conduit bends in wall

[phatboy]

Hi,

I am doing some chasing out work soon to add some electrics in a bedroom.

This will be the first time where I have not had access to the ceiling space to route cable via. I will be going from a FCU down to a flex outlet for a heater. They are not directly above each other though, so a bend will be required.

I usually use 20mm oval conduit, but there don't seem to be bends available for this. I could use 20mm round conduit with bends, but this will mean channeling deeper.

Are there any other good solutions?

Thanks!

Are you planning on it having to be rewired anytime soon. If not just use some capping by cutting some 45's to form a 90 ?

No rewire planned, the electrics aren't very old so its just an addition.

I guess I can use capping with 2 45degree cuts... just wondered if there was a better way to do it!

Thanks

It is unlikely that you will be allowed to bent the conduit it the wall.
Cables must run horizontally or vertically to an accessory.

They will be. Horizontally from the FCU and vertically to the outlet (or vice versa)

Ahhh right, I must learn to read properly !!!!
Phatboy have you got a photo or diagram ??

What about something like:

The corrugations might cause a slight problem though...

Maybe a slip bend http://www.tlc-direct.co.uk/Products/MT20BNDslashS.html with deeper channeling at the direction change. And squeeze the oval conduit to get it to fit the circular bend.

Touch and go if you can get the fish tape through though. Still you only have to do it once.

Why not just mitre the two bits of 20 mm oval?

Can you imagine pushing/pulling a cable through a sharp right angled bend? It has to be gentle, like a slip bend.

15mm copper or plastic pipe. And a pipe bender.

Am I missing something here?

This is just regular twin and earth cable in oval conduit in plaster? With no particular attention to new wiring being pulled through in the future?

The last piece of conduit can be slid over the cable once a bend in the cable has been formed.

What is the problem here? Clearly I am misunderstanding...

OR ... just bury the cable in nice cooling masonry.

Or get a grip, get out the Hilmor and get on with bending the right sort of conduit.

To my mind there's no point in using conduit if you can't pull the wire through. You might just as well clip the wire to the wall and plaster over if you don't want to do it properly.
