Conduit for 2.5mm T&E Ring main

[bobveal]

Hi all,

I am currently fixing up a room in my house and after removing some built in bookshelves found that that wiring for the single socket in the room was surface mounted on the walls.

Given I'm doing a fair amount of plastering in the room I would like to re-route the wires through my loft and then drop down to the socket chasing in the wall.

The questions I had were regarding the use of conduit.

1) Which size do I need if I am running 2 x 2.5 T&E cables
2) Should I use oval or round?
3) Can I still pull cables through the conduit if I have to use a 90 degree coupling?

Thanks in advance for any help you can give me,

Rob

i would deffo use oval. straight drop from loft to socket. why the 90deg. coupling?

Hi there,

thanks for responding so quickly

My house is thatched and hence I believe I need to run the cable that is in the loft also in conduit so I was guessing that I need to connect the conduit coming from the rest of the main to the conduit for my drop?

of course I may have misunderstood what you meant

Thanks,

if you use round 20mm conduit with an bend, you can pull 2 x 2.5mm ( don't use a tight elbow ). however, if it is only 1 socket outlet, you could just spur off the ring with 1 x 2.5mm

If you live in a thatched roof house I would get a qualified insured electrian to do this work. With it being thatched I assume it is a listed building? What would your labc think about this or your insurance company? Just a word of warning.

use 20mm round imo here in n.ireland oval is a thing of the past. The round enables you to rewire the socket at a later date more easier..

Seconded - wiring in a property with a thatched roof is a whole different ball-game, particularly with cables in the roof space.

Hi all,

Thanks for the posts and I appreciate the advice. Always annoying when life gets difficult trying to upgrade something that I guess wasn't done right in the first place.

Anyway, 3 pros have been called and I await the quotes and also :-(

Thanks,

Rob
