Solutions for Surface mount to conduit.

[Pat H]

Anyone got any other solutions for getting from a surface mount socket to surface mount conduit (plastic)

I often have to add a radial spur from a ring main socket.
Assuming I need to retain the double gang 13A outlet I either:

Add a single gang back box next to the double socket.
Stick a Fuse Switched Spur (can be RCD'd if ring final isn't)
Take the output from that to one side in the wall and then out into a conduit terminal box. Then extended the conduit as required.

The other method is to use a surface mounted single gang back box for the FCU and extend the conduit from the side of that. The cable from the double gang 13A coming out into the back of the surface FCU.

Any other neat solutions to get from below surface to over surface conduit?

I have read this a few times but I don't get what you are trying to ask.

To avoid a thousand jumbled words Marshall Tufflex is the solution.

If I've got it right, you've got a RFC chased into a wall and you want to extend off it in conduit? I've not done this so far. For aesthetics I extend using the same installation method. Maybe I've misunderstood?

Yes that's correct and if its practical I'll extend by chasing but its not always the least cost solution for a cost aware client where cost and a practical solution are of more concern than a visually nice looking option.
Coming surface mount with conduit allows faster coverage of ground and far less mess.

Once I start chasing out and then making good it takes longer, makes more mess and costs more. Obviously where visually it has to look good its the only option but often its in utility spaces and the conduit is behind white goods etc anyway.

Both of the methods above I use and work fine just looking for fresh ideas. So yes chasing and hiding it all is an option.

Ok, got it. I'd take the last 2g outlet from the wall and plaster hole. Then proceed to pattress away using one with conduit knockouts. Cheers.

 

[Pat H]

Ah that's a neat idea. Thanks

How would you extend the wiring.

 

[Pat H]

One option would be this sort of idea:

Basically a pattress that sits on top of the original back box. (you need really long screws!)
That way you can use the original back box as a junction box for the short cable feed to the front box.

I'm not sure if I got this right......but when I've had to spur off a flush socket, and run the new cable surface, I've used one of these for the original socket; https://www.amazon.co.uk/Single-Dou...coding=UTF8&psc=1&refRID=FS1SF9QPER15YST2WF3Z. Same depth as 16mm trunking.

 

[Pat H]

That works fine if its a single gang flush socket but most of the time I seem to be faced with a double gang. And often they don't want to lose that double gang. But bringing the double gang out to a pattress and then extending sideways to a FCU in a single pattress and then from that with conduit would work.
I just need to do some more digging on various adapter to have a selection of choices available. The more choices the easier to find the right solution.

That is a poor solution in my opinion, those screws will never secure the new box correctly and you could argue conductors into the box are not correctly contained. I have yet to see a "neat" solution for this.

I dunno, looks okay to me. But again, its converting single gang flush socket to twin surface, not twin flush to twin surface.

I did a job like this recently and use a pvc double box over an existing single:

 

[Pat H]

Yes that's just the sort of thing. Its just that I rarely get a single socket they always seem to be doubles.

I see you have used pvc fixings over that door.

 

[Midwest]

Perhaps its not an escape route

Good point. This went in just before the latest regs.

 

[westward10]

Perhaps its not an escape route

If a door from a room leads away from a hazard to a place or route of safety it is deemed an escape route and from the picture I suspect it does.

 

[westward10]

I am being picky here cos it looks a good job, do you think the conductors into the new box are correctly contained.

As it has a closer I suspect it is an escape route. But why worry about the wiring with a flat screen TV mounted above the door? I'd worry more about that falling on my head as a fireman..

Would some metal conduit clamps over the plastic above the door be enough to be compliant?

Steel saddles are a solution and easy to retrofit.
You would be pushed to find any door which would not be part of an escape route in a commercial premises.

On more than 1 occasion, in threads, its become clear after numerous replies that you eventually provide additional useful information.....

Your house or an unsuspecting customers?

best watch out for the next cowboy spark who sees that and states its "illegal"

Sorry if my eventual additional info is useful. (I think not really sure what that is)

read my profile info it tells all there is to tell.

I have posted posts related to my house and others related to customers or just general questions.

No sweat. I didn't understand it anyway

Not quite sure what you mean. The new box had an RCD socket fitted. Wires either went into the socket or were joined with Wagos to complete the ring.

 

[westward10]

Like a said being picky but there is no containment for the conductors between the existing back box and the new box aside from butting them together.

I don't get it, there is a KO box in the wall and a surface pattress over the top as long as the KO box is earthed I don't see a problem. Why would it need containment between the two?

 

[westward10]

It is nothing to do with earthing but the containment of conductors between the two.

Why does it need containment out of interest? You wouldn't put containment between a flush box and thermostat/programmer back plate for example IMO its a similar scenario.

Using that definition, that would mean every room in any property in every premise is part of an escape route? I'm not sure about that.

The conductors stop at the accessory and are contained within the back box. In this instance although as I said being picky they pass between enclosures . Would you butt up two conduit terminal boxes through a thin partition without some forms of bush. I agree in this instance it is an air space but it is that space where containment is absent.

 

[westward10]

Give me an instance where a door may not be an escape route. If you have passed through it there may be a requirement for you to pass back through it an emergency situation, even the door to a toilet cubicle. You are sitting on the loo and the fire alarm goes off that cubicle door is your escape route, far fetched but true.

 

[HandySparks]

...I agree in this instance it is an air space but it is that space where containment is absent.

No absence of containment. The building structure is permitted to form part of the enclosure.

 

[Wilko]

Hi - my 20p worth - aim is to create one containment, consisting of the original back box, the new pattress and the face plate. If successful no additional segregation or containment would be required. The new containment would need to be rigidly joined and pass IP-wise, which it looks like. Or have I misunderstood? (Prolly not enough unpickled brain cells left.)
