Extend SWA to consumer unit

[Gavfromengland]

Hi guys. I have an old out building that has been knocked down and in it’s place an extension is being built. The old out building had a ring and a lighting circuit with water heater for a shower all fed From a ccu that came from the main house through 10mm swa. The extension is now going to be fed from this same ccu. However I want to move the original position of the ccu. Can I extend this SWA? And how??

resin filled joint.

Hi - yes SWA may be extended, but you probably will benefit from the on site help of an Electrician. SWA is a specialised cable and there are a few skills to getting it glanded correctly.

As above, the electrician doing the electrical work will have no problem extending the SWA.

Bald above ground in an ip box and secure to something or as above proper resin joint buried

Bald above ground

That'll be your age that.

Yes, resin joint, or wiska box a picture would be handy for better options

Given a choice I'd definitely go with the above ground accessible for maintenance junction box.

Assuming it is 3-core 10mm SWA then something like this (if 2-core they reccommend the S6 kit):

S10 10-16mm Straight Resin Joint Kit for Cables up to 16mm 2 Core

Proven underground cable jointing system

www.cef.co.uk

But you have to read and follow the instructions carefully. Really I would not plan on doing your first resin joint for a "it matters" buried location...

Hi guys. Sorry it’s overground. Going to have ccu one side of corridor now she what’s it other side of the corridor. As you can see in picture. SWA is on the right where ccu was going to go and cables on the left where ccu is now wanted. SWA not long enough to feed other side of corridor.

I don't want to be critical here but what are you finding difficult about extending that cable a few feet across the door.

Extremely simple job. It is concerning.

 

[Mike Johnson]

It is a concern, but to be honest I would chase out the floor and take it across to the other wall, or just tell her it, cant be moved. ?

Its only a difficulty because I’m not on site yet .

 

[Vortigern]

Wiska Shark is what you want.

 

[GBDamo]

Surely it can be pulled back and channeled through the floor then back up the wall?

 

[Dustydazzler]

Grinder , small chase , get in in the floor and up the opposite wall.

no need to joint

Oops ?, didn't see youd already suggested the obvious.

This is getting silly now....

It's as my Farther used to say about some of my friends "If he had an original thought, it would be lonely" ?

What are those cables in capping above the door? They are not in a safe zone and non-compliant if mains voltage, unless they only come down 150mm..

that's a 9" cinder/concrete block. add the timber ad the drop is about a foot. ( that's 300millipededs for the young sprogs).

Doesn't mean the cables go all the way down the capping though....but I suspect they will do.

 

[telectrix]

uless it's an outside lightover the door. that would make sense.

 

[Gavfromengland]

Cable isn’t long enough. Chased through the floor or not. Capped cable not ideal but is literally the closest to 150mm it could go as it feeds outside light. Couldn’t go any higher due to roofing.

 

[brianmoooore]

Hole through wall should have been drilled upwards at an angle from the outside, so that it is more than 50mm deep inside when out of the safe zone.
That SWA looks plenty long enough in the pic. to reach across the floor and up the wall to a CU at the correct height. Are you sure it's not long enough?

 

[Gavfromengland]

Yeah not long enough. Height is fine but would be directly behind the door.

I know...The standards on this forum have really dropped lately. So disappointing.

Fit it above the door, all cables will reach including the SWA.
