Wago's inside conduit?

[DaveAbbey]

Hi all,

I'm thinking of adding some additional sockets in my (domestic) garage - the plan is to run the circuit inside rigid 20mm conduit along the top of the wall, then teeing off and dropping down inside conduit to sockets in surface mounted pattresses.

Can I use Wago/Ideal type connectors for junctions inside the conduit tee boxes? - these will be accessible and held shut with screws, if so, do I have to provide a method of strain relief for the cables?

Why T off ? You are introducing unnecessary joints. Link cables at sockets

God knows why that never occurred to me! Thank you.

In days gone by it was very common, especially when running T&E in conduit for lighting circuits.

Whese days I'd not expect to find connectors for new work, making later alterations is a different situation but still not my first thought.

I expect it will be a pain running 2 lots of 2.5mm T&E in conduit. Ok for short and STRAIGHT lengths.

I suspect you will end up wanting some joints. I don't see any reason not to use wago's. With the cover on, its insulated.

The obvious choice is to run horizontal conduit between the sockets. Quicker, cheaper, less electrical issues. But if you have bits of wall sticking out, I know its a pain

The number of joints in the cable run is exactly thge same in either case, the only difference being the location of those joints (in conduit boxes or at sockets).

As for "why do it", if one wants the main cable run to be at the top of the wall, it will nearly always require a bit less cable, and getting one cable through conduit is easier than two (2 x 2.5mm T+E in 20mm conduit may not be easy). However, linking the sockets directly by horizonal cables at sockets level would both reduce cable length a bit and also avoid having to get two cables into a conduit (if used).

For what it'[s worth, in my in-laws 1980s-built bungalow, all of the sockets were on unfused spur drops from a ring in the roofs[ace.

I've never seen this done, seems like a lot of unnecessary effort, if you are chasing 1 cable down you might aswell chase 2.

 

[AndyPRK]

Probably done when its the same Ring up stairs and down stairs.
Thus the ground floor sockets are spurs

Ahhh I get it now, I was imagining junction boxes above.

Seen this method in a stone built cottage with bare walls, single T&E following the mortar between stones

Ok, so it's just a way of running one cable down instead of two, good idea.

I would not be critical of a job where only conduit was run, without using any boxes, elbows or etc., for T&E, leaving the cable exposed where the boxes would be. Always assuming the conduit had been installed for neatness, rather than needing mechanical protection.

The OP is not talking about chasing but, rather, about cables in conduit. As said, getting 2 x 2.5mm cables into a 20mm conduit is not necessarily a trivial task.

As for your 'never having seen it', as I said, I quite often have - and, indeed, it's how the sockets are wired in my garage ... or were yiou perhaps talking about my in-law's bungalow?

If you're talking about my in-law's bungalows, there was obviously no 'upstairs', but all the sockets (all on ground floor) were spurs from a ring in the roof space

Singles is the cable for conduit not T and E.
