Running Conduit into outside sockets.

[Tiny Spark]

Howdy all,

Looking for some opinions/advice Ime planing out a job for putting power in my shed.
Plan is drill through a socket on the ringmain in the living room wall to the outside, Fit a IP66 FCU with RCD protection, Then off that to a IP66 double socket, then onto my shed with SWA for another socket and light.

Nothing to hairy.

But I was thinking of the best way to join the FCU to the SSO in terms of keeping them watertight as they will be obviously be open to the elements.
So I was thinking of using these:
Masterseal IP56 PVC 20mm Conduit Entry | Outdoor Cable Entry | Screwfix.com

Out the bottom of each unit and then have a bit of 20mm bent between them.

So heres my questions:

Firstly do the above seals work with any 20mm knockout or will the only fit the MK range as Ime planing on going with BG stuff to keep the cost down.

Secondly in terms of drilling through the external wall is there a minimum height to go past to avoid any damp course etc as I cant see any membrane or anything like you sometimes do (house was built around 98 if thats any help) Also what about sealing the hole back up around the T&E cable?
Best to use silicone or just put some mortar around it?

Cheers all.

Flanged couplers with neoprene washers will seal quite nicely against a plastic enclosure

true but if its just a stub between them plastic will do.

the plastic will never loosen though and i dont like using 20mm bushes because the ones now are so thin they start to deform before you can get them really tight

I don't use male brass bushes anymore unless I have to.

you would to fix to the conduit though we use a lot of them and i hate them. i really need to buy a bush spanner.

you cant always get your 21mm socket in

No I don't, locknuts, serrated washer and a female bush for entry to normal enclosures, or a nipple, serrated washer, locknut and female bush if a flange coupler is needed.

that's why you leaqrn to use a hammer and chisel to dog 'em up tight.

Well i managed to find a sort of double ended rubber grommet thats designed to join 2 masterseal boxes together so I have ordered one of them.
Also means there wont be a big gap between them keeping them looking neat

As for the bushes I use one of these:

The flexible head makes it ideal for those hard to reach areas.

I can't post a picture of my bush wrench for reasons of decency mg_smile:

 

[uksparks]

why dont you just fit the FCU on the inside next to the plug and drill through from that to the back of the new socket?

 

[uksparks]

like so....

Cheers Tel,

I wasnt going to bother tubing through the wall just a T&E straight into the back of the FCU, I was then going to Tube between the FCU and the SSO and then Tube the socket and lights in the shed. Oh and the outside light that will be on the shed LOL

YEEE ... HAAAAAA!!!!! .:cowboy:

Mind you don't trip on your spurs on your way out!
