joining thin stranded

[JohnD]

This is about the thin white functional earth tracer wire on MEM RCBOs.

Current load is negligible.

It looks like (say) 0.5mm stranded. If I need to extend it, it is smaller than any of the crimps I have. I was thinking about weaving the strands onto a bit of bell-wire and soldering them, then applying heat shrink (though it is also smaller than anything I have).

It might be comparable to joining Alarm wire.

Is there a better way?

(and don't say twist them together and smother in tape )

I assume you mean stranded bell wire?

If so then I reckon twist - solder - heatshrink is going to be absoloutly the best way to do it.

Ta!

No red through crimps? You can solder or if you want to or if the terminal is accessable you can use terminal block (not as nice tho).

I have got some red ones, and a CK ratchet crimper to fit, but these wires do seem terribly small... and they're stranded. I've never done anything smaller than 1.5mm solid core before.

Not sure I'd be too happy running cable thats not intended for mains use around inside a DB... insulation standards and all that.

I'd strip them both back 15mm or so, twist one over the other, solder and heatshrink

 

[JohnD]

the white trace wire is very thin and lighly insulated... do you know the stuff I mean?

I suppose I could extend the heatshrink over the new section (this is for use when it has been cut back too far and needs to be extended to reach the earth strip... these RCBOs are a bit too expensive to scrap

Ring MEM on 0161 652 1111 & ask them for a bit of the same wire to extend it with.

The red ones generally go down to as far as 0.25mm², what make are they? If you are worried of the connection you can always double the wire over on itself.

No!!!!

You'd be surprised how helpful Co's are.
