moving cu.

[i=p/u]

seemed to have bagged another house extension happening in my street. way hey..

but he wants to move cu about 1m to a box on the new wall. but keep existing dno equipment where it sits

as its under 3 meters i can just install new tails.in a duct in the ground going up cavity of the wall.

rcd the tails or not?????????????

- - - Updated - - -

all existing ciruits and new circuits will be rcd'dddddddddddd

 

[Knobhead]

What sort of duct?

 

[Strima]

SWA from an isolator?

 

[i=p/u]

16mm swa sounds good as only 60/80A fuse on the carrier. what sort of box would i use to gland the swa at meter equipment as im using plastic cu aat new position..

 

[i=p/u]

you dont just gland it and and attatch to banjo, seems ruff

 

[Strima]

Gland and banjo will work but you could gland into a galvanised adaptable box or steel trunking then leave enough cable to go straight though and terminate in the CU, also helps you maintain the IP rating of the CU. I would personally use three core and some decent size cable to bond the box/trunking so both ends of the SWA are earthed.

 

[i=p/u]

yh was just looking at metal adaptable boxes... i am under the impression i only have to bond at one end if using 3 core??? correct me if you think im acting the monkey

 

[Strima]

You only have to bond at one end however I believe it's still best practice to do both, with the gland kit you normally get enough to do both and you'd get no earthing problems...

 

[i=p/u]

so 16mm pvc/pvc from dno equipment to isolater , 16mm pvc/pvc from isolater to metal adaptable box, swa from adaptable box to new cu on front wall of house( about 1.5m max) and gland and attach swa to platic cu and having fly lead to earth bar in cu.

would i have to have iscos inside adaptable box

 

[Knobhead]

Earth both ends, make use of what’s available.

Why not run the tails in an earthed steel pipe?

 

[Guest55]

.......... correct me if you think im acting the monkey

couldnt resist lol.

Why not run the tails in an earthed steel pipe?

Same Thought here. or even in some steel trunking. under 3m isnt it for tails?

 

[i=p/u]

yeah its under 3m and will be going up centre of cavity i think.. which is 100mm brick each side

 

[i=p/u]

will i be the one in a million that uses the the pipe as cpc,
