    Hello, whats the best way to join 2, 6mm cooker cable together to extend it so i can move the socket. Will a yellow butt connector from toolstation work? The cable runs through conduit not chased inside the wall thanks

    There are loads of methods [​IMG] but main point is the physical protection, in the main though would use a cooker connection unit [​IMG] as it also marks where the cable runs so complies with safe routes.

    If you use butt connectors then you’ll need a proper ratchet crimper. Even then, crimps on solid conductors aren’t the most reliable, I would avoid crimps for a high current application like this. you’d also need a BLUEcrimp for the earth wire, because it’s a different size.

    Wago do a connector that goes up to 6mm². May be the better solution?

    Best way is to solder them and cover with heat shrink then self amalgamating tape.

    Winston... Have you ever actually tried to do that ?

    If you did and it was successful can you provide detailed instructions.

    I don't think I'd advise a DIYer to attempt that.

    I'm not particularly sure I'd want to bother with all that anyhow, sounds a load of effort for something that's going look a mess.

    Many times. I don’t need to tell you how to solder surely.

    You could tell the op.

    For instance, would the op need to twist the strands together, or what?

    Some soldering techniques differ, I have seen people remove several inches of insulation to make some very pretty knots before soldering.

    Yet this wouldn't be possible where cable length is limited.

    How would the op solder these cables to get a good solid joint that isn't going to break?

    I agree, definitely not something I would advise.

    Just tell me how you put the heat shrink onto the conductors before soldering them and keep the heat shrink sleeve cool enough that it does not shrink before it can be sld over the soldered joint.

    It can be done but requires a lot of the cable's sheath to be removed so the the heat shrink can put on the conductors before soldering and kept away from the heated area of copper until the soldering is completed..

    to replace the cable sheath that had to be removed

    Or are you advocating this type of soldered joint where the heat shrink does not have to be put on the conductors until after the joint has cooled

    Why have i always been told you cant solder 230v. I do a lot of soldering on cars 12v system and now im reading on this to just solder. What's the difference soldering on the 230v or 12v is the solder different or something

    I think the wires are so thick you need to get a lot of heat in. And somehow prevent the heat shrinking before you want it to.

    And put a layer of heat shrink to replace the grey sheeth

    Who ever told you that was wrong. Many electronic devices have numerous soldered joints in them and some have voltages inside them well in excess of 230v.

    Re the various 'how to solder posts above' it appears you are experienced at soldering so I won't elaborate further.

    Is that because you cannot elaborate on your statements about soldering 6 mm conductors

    Nope. I have been soldering for well over 60 years and know how to do with even bigger stuff that 6mm conductors.
