Moving Fuse/circuit board - extend wires

[baker332]

Hi,

I'm need to move my circuit board that supplies the house over to another wall - it needs moving maybe 30cm no more. My question is, can the electrician lengthen the cables that are already in situ or would this need a rewire?

Thanks

The distribution cables (stuff going to lights, sockets etc) can be extended. This may involve a box on the wall where the CU was. You may run into safe zone problems if you planned on burying the cables.
You/your electrician cannot move the meter, cutout, supply cable to the house. If there is an isolator between the meter and your CU then you can install longer tails (there is a maximum length).

To confirm its' the circuit board nothing to do with the meter and there is an isolation before the meter therefore no requirement to pull the main fuse.

The issue I have is that the CB is on a wall that is going to be removed, therefore I cannot have random junction boxes placed there, can these connections be crimped?

You really need sparks to look at this on site as there are a few variables

Extending the meter tails is nearly always a problem

Yes connections can be crimped or soldered but they need to be done properly

What is constituted as properly? If electrician, crimps both ends with crimp connector and tool, does this then need to be heat shrinked and can be put behind a wall instead of a junction box for maintenance etc.?

Is soldering within domestic even a thing? Surely that would break down over time with heat and current passing.

Yes, it is one of the acceptable methods for hidden joints - if also done properly.

Properly means the joints must be electrically and mechanically sound before soldering.


Also: solid cores should not be crimped.

Well, learn something everyday, cheers!

I've never had the need to solder a wire, what's the point? So many better options

This may come in handy

Thanks for this, depending on wire length and how much room not sure if there is somewhere to fit this, as the wall is coming down. Will keep in mind with discussions.

I think you should see what the builder / spark suggests

 

[baker332]

Yep will do. cheers all

Do share what they suggest with you because it'll be awfully messy when you need to access this later

What is above the wall you are planning to remove?
