CU Change and extending circuit wiring

[d3jpt]

I am changing my home CU for my NIC inspection. At the moment i have a rewirable fuse CU in a 1960's house so thought its about time its changed. On initial inspection everything seems in order, ok it all need to be brought up to 17th standards and none of the lighting circuits have an earth but it doesnt look too bad.
One thing is though there isnt enough slack on the cable and every circuit needs extending to fit inside the new CU. My question is as it needs to be inspected is what would you use to extend the cable for each circuit? I was tought that red/blue/yelllow butt connectors are fine but just not really sure about these. what would the NIC say?
cheers for any advice

first, if all cables come from above, can you not fit the new CU higher up.? second, if not, i would get an adaptable din rail box with din rail terminals and extend using that. however you extend, the joints must be enclosed in a box or trunking or similar.

There are numerous ways to extend cables. Aslong as they are mechanically sound. Alot of people use crimps. Forgot what the industry name for them is.

^^^^^^ as above IMO far better than crimps in this situation.

Tel's suggestion

 

[High Tower]

adaptable and din rail
adaptable and wagos
trunking and crimps

take your pick

 

[topquark]

If you go the route of wagos, watch the current carrying capacity of the wago is adequate for the cables maximum rating (even if the breaker is considerably lower in value).

Cheers for the sugestions, The CU is in the garage which is attached to the house all the cables are coming through the wall.
I will look into the adapatable din rail, Just got to make sure its right.

and if you use an adaptable box you can label i german " Achtung, Gerfingerpoken Verboten"

/I know thread is a week old but ive used wagos to extend the wires here's a pic and before you say it it had grommits on when i finished it and i had ran out of green and yellow wagos , if you 've not used them before then these are the push fit din connectors

Nice and neat, how long did that take you?

nice job there Nick. thats my prefered way of extending when doing a cu change

Very neat Nick. You can do my hair anytime (not that I've got any left).

How good does that look. i use an adaptable box too. although its neat, i wish i could say its that neat.

Nick may have now raised the standard of these cable extensions

We will all be trying to match him for quality pretty soon then

nice neat job, nick. just think it would have looked so much better with red/black cables .LOL
