Hi, Great site you have here guys. I`v being watching for a few months, and now have a question.

In colege, they have told us that when wiring in steel conduit, all wiring is done in single core cables, as opposted to Twin+earth.

Is there a reason for this?

Would seem logical to me to use Twin+earth, to keep things tidy...

Thanks in advance.

Richard

yes'm...gonna need some pretty large conduit or numerous smaller runs if you're gonna be using T & E and would be hellish to draw cables in...also would have to sleeve all your cpc's too...pain in the arse when there's no need....singles are the future, i've tasted them. ;)

I think they use singles in domestic work on the continent don't they? I know they use conduit - brilliant for re-wiring.
 
hiya, glad you've started posting ;) , i think its a right pain getting say' 2 x twin + earth down 20mm conduit, like Grae said its the furture. rather not get bogged down feeding cable down a tube all day, when ya can be doing something more productive,

If its steel conduit ,you can always try putting the neutrals in a seperate pipe,if you dont have room .anything for a bit of fun,

Gents, if you were to run twin and earth, how exactly would you work ouit your conduit factors?.......:rolleyes:

cos' you do work out your conduit factors dont you.....? chaps....?:rolleyes:

the tables only have singles in them.

if you used twin and earth you would have to greatly change your factors because of the additional insulation in there......

and neutrals in a seperate pipe, hope we're not going down the route of single conductors in ferrous enclosures here........:eek:

I had a similar problem years ago,doing council rewires,all the switch drops and some sockets were 3/4 inch conduit,but it wasnt a conduit system as such ,so we had to use tae which was a very tight fit and not a very good job ,,the reason they were conduits was the walls were solid concreate and the pipes were obviously installed before the concreate was pored,some guys stripped the tae ,but this was considered bad practice by most.the whole job was a nitemare,and took ages
all the very best in the world

and Tony,i was only joking about seperate pipes for the neutrals , its not a good Idea!

Like i said guys, if you put twin and earth in conduit, then you cant possibly have worked out your conduit factors

are you chaps suggesting you DONT spend 2 hours in the regs before every job???:rolleyes:

that takes all the fun out of it:D

regards

Tony (promising to get out more):eek:

Embarrasing question
Singles-does that just mean separate wires
One neutral wire one cpc wire one line enclosed in conduit
Rather than the all in one cable t&e
