Connecting outside socket to internal supply

[JamesG17333]

Hi,

I am installing an outside socket but had a question about how I can connect it to the internal supply. I have tried to represent my options/plan in the attached image. Are there issues with either of these approaches?

Additionally, does this work need to be approved/signed off in anyway or can it be done as a DIY job?

Thanks

scrub top pic. that's for wimps.
you don't need a FCU as long as the internal socket is not a spur, and there's only 1 outside socket (single or double). it also only needs to be an RCD socket if the house ring final is not RCD protected in itself. a Minor Works Cert. is desirable, but it's not notifiable work under part pee.

Also what cable are you taking to your socket? Pic says "swa 2.5mm2 t/e" which are two different cables? Needs to be 2.5mm 3core swa scrub the t/e bit

How the frig are you going to terminate that swa cable?

I’m not even sure you need swa

Take the spur cable straight outside fit a IP rated SFS nd take the SWA to the ip rated twin socket, gland into the spur and the twin socket

Sorry Pete
I can’t understand how the swa is going to be terminated in too the plastic outside socket and the switch fused spur, and still have fault protection with the armour ?
And why is a switch fused spur even needed.


And why swa?

outside socket remote from house, ergo... SWA. what's the problem with terminating i a IP65 socket box?

None what so ever.

Thanks. What is the SFS you mention?

 

[Hoon]

how remote is remote?

There’s no reason it has to be swa.

Thanks. Although for wimps is it viable? Allows me to plug and unplug as needed and not mess with a spur off the socket which is a little way from the wall.

I am actually looking to do this in two different places so may do a different approach in each based on use case.

Switched Fused Spur

Quite right you could use conduit, but SWA is easier to install.

so, if on a plug top, you'd not fix T/E into a plug top, would you. if you did i'd come all the way down to that den of iniquity (london) and spank your arse.

You are not an Electrician the I take it, do you have the experience to do this work, even more important do you have the necessary test equipment, needed to test the installation after you have done it?

Personally I would advise you to get an Electrician to do the work, test and inspect and issue a certificate, on completion.

I know of no reason why pvc,pvc can’t be clipped direct outside. Why does it need to be in conduit?

Twin & earth may degrade when exposed to ultra violet rays and become brittle. As it is also very easily damaged, mechanical protection by conduit may well be required.

SWA offers a ready-made solution to these potential pitfalls. If no mechanical protection is required then use Hi-Tuff.

Personally i like to have a FCU inside the property so if for xmas lights etc it can be switched off inside, i would tend to make off swa gland in rear knockout of a 35mm 1g metal box then drill straight through the wall and hoss the cable through and clip to wherever said socket needs to be (obv larger dia hole for a short way into wall to accept the gland, then 15mm the rest)

^^ making the SWA gland inaccessible .. Not ideal imho

I agree.

Under such circumstances I would drill a hole through the wall from the inside out, insert a piece of 20mm PVC conduit and fit an IP65 adaptable box on the outside wall. 2.5mm T&E would then be taken from the socket and terminated inside the adaptable. SWA or Hi-Tuff from the adaptable to the outdoor socket. Sorted!

Never going to come loose in a million years, (well maybe 100) saying that id still use 3 core and banjo the other end anyway, no different to the people that put them in boxes behind consumer units and bring the cores through

Sorry Suffolkspark, I disagreed with your post for the reason that the gland would be inaccessible, as some others have pointed out as well.

 

[suffolkspark]

Pete you don't have to apologise, we all have different ways of doing things, I've never come across a gland that's "worked" loose only where poorly installed initially, and with it earthing the armouring not serving as the cpc,,,, and that being done at both ends,,, and it being in the wall can't be disturbed,,,, and all actual connection being done into the FCU so no inaccessible joints or additional adaptable boxes on walls outside, I just feel its a pretty simple, tidy way of doing them.

OK like you say we all have differing ways of doing thing, but your method is not the way I would do it.

Not worked loose ................... but corroded - yes

Absolutely. I was planning SWA (for protection through the external run) in to a junction box (or similar) with standard cable flex coming out of the junction box to a plug. Essentially a long extension cable as mentioned earlier but with SWA to give the wire protection outside.

 

[telectrix]

I agree.

Under such circumstances I would drill a hole through the wall from the inside out, insert a piece of 20mm PVC conduit and fit an IP65 adaptable box on the outside wall. 2.5mm T&E would then be taken from the socket and terminated inside the adaptable. SWA or Hi-Tuff from the adaptable to the outdoor socket. Sorted!

my preferred method would be similar, but instaead of T/E, I'd continue the SWA cores through the wall in conduit (back entry into the ad. box,) and direct into the FCU, obviously with a fly lead to the gland, thus eliminating a joint.
