Moving cooker socket

[markdiynot]

Fitting new kitchen units
Can I move the cooker isolator socket
Need to drop it down about 50cm
Can I put a joint in that cooker cable

If done properly, yes.

All of the cable run in the wall needs to be in a 'safe zone' if less than 50mm from the wall surface.

Also, how do you intend to extend the cable?

The join needs to be maintenance free, which means no screw-down connectors.

One option may be to do the join above the ceiling, or inside a kitchen wall unit, if easy.

How would the joint be made so to be maintenance free ?? Soldered ??

could I use a surface mounted joint/ connection accessible for maintenance purposes and have it accessible in the new wall unit which will be covering the cooker switches existing position
The connection not being buried in the
wall but fully accessible

 

[sparkwright]

Yes, you can do the joint in the new wall unit in an enclosure such as a pattress and blanking plate, and use screw down connector blocks or wagos.

The connectors most likely need to be rated at 30amp or above.

Soldering is not a good idea for DIYers.

Rather than having it buried in the wall in the pattress making further work could I use a standard high rated electric connrction box , surface mounted on the wall accessible through an opening in the back of the new wall unit

 

[sparkwright]

I was intending you bring the cables through a small hole in the back of the unit, then screw the plastic surface mount pattress to the back of the wall unit.

This should look tidy enough.

Alternatively, cut a square hole in the back of the unit the size of a single metal knockout box, fit the cupboard with the cables coming through, fit the metal box to the wall, do the joint, fit blank plate. This way it's nice and flush and neat and not in the least bulky.

Why?

 

[markdiynot]

Brilliant many thanks
much appreciated with prompt reply this time of night
Will get on with it tomorrow
Being unsure was holding up continuing to fit the cupboard

 

[sparkwright]

Why?

How would they do it properly?

You can't just tell someone to solder a cable and leave it like that.

Perhaps you could kindly put into words how to solder a (6mm2) cable that is partly buried in a wall?

It’s all gone quiet…in fact he has been very quiet for the last week or so. Same thing for banal sheds on the Screwfix forum.
hmm. I don’t suppose they are linked in some way..?

These might ( NOT ) be the answer

Found this modern method on that site

They would be ideal if they contained a lot more solder.

Used to use this https://www.exothermic-welding.com/ system for brazing/welding copper cable to re-bar, and they claim the usa wiring code state it is the only acceptable method. Anyone with some spare time - ie everyone - should invent a mini version for small cable jointing. This time next year yule be a millionaire - see what I did there.

We had those for joining D10 or D3 field telephone cables when I was in the CCF!
