Cut through the sheathing of cooker cable.

[Kkiernan09369]

Curing the floorboard in room and the cooker cable that runs through a notch in the joist was cut. Through the grey cable and the tips of the brown and blue wires. Just enough to see the copper core.

whats best to do in this situation as obviously I don’t want to replace the whole cable

is there any slack in the cable?

Yes I’d say about half a meter

Will it be okay to cut and secure in a suitable amp junction box?

 

[telectrix]

easiest solution, without cutting cable, would be to stripp back the outer sheath, wrap each conductor with some self-amalgamating tape over the cuts (several turns), then wrap the whole lot in some more tape so that the cloured cores are completely coverd. this assumes no damage to the copper core, in which case cutting and jointing would be required, if in doubt, get a local sparks to fix. whatever the case, isolate from supply before hand.

Make sure its self-amalgamating tape and not the cheap insulation tape.

I have asked an expert and I will follow your expert advice. But just out of interest. Why would Norma insulation tape not be suitable?

If you opt for a Joint Box (JB), and if it is not accessible the JB would need to be Maintenance Free (MF)

Is this type considered maintenance free? If not, why not?

No Mate because it has screw type connections that could work loose, and doesn't have cable restraints

So I assume it’s the clamp type connections inside a wago box or similar? Can u get the clamp type for a 40amp

 

[Pete999]

Urged! So I assume it’s the clamp type connections inside a wago box or similar? Can u get the clamp type for a 40amp

Wago connectors and the right box would be the right way to go, not sure if they make the size you rquire, try google and see what it says, I was thinking of a resin filled joint but I don't know it they constitute MF or not, good luck in your search.

Ok so let’s go back to self almagat tape. What exact is it? It’s on description online non tacky? So how does it stick? What’s the difference between that and the normal electrical insulation tape

Self amalgamating tape does just that , the surfaces react with each other and form one continues moulded joint . You have less chance of any ingress of damp and other nasties , as opposed to insulation tape ; especially the cheap tat that is common now.

Thank you for your kind help

Self amalgamating tape won't start coming unwrapped over the years either like insulating tape often does x

Couldn't have put it better.

Self amalgamating tape stretches and has a backing tape which has to be removed. When you apply it you stretch it until it is about half its width and wrap it around the conductor. The tape combines with its self to be one rubbery blob that cant be unwrapped (self amalgamating) finish with two layers of good quality insulation tape applied with a slight stretch.

You are very welcome.

And the tape is defiantly okay for 42amps cooker cable?

It's the voltage that is the key factor for the insulation, rather than the current
