How to Extend a Short Cable

[@John-ou4rm]

As mentioned elsewhere needed to explain what double insulation entails. And whether inline crimped connectors need to be in a separate box or can be embedded in a plaster wall like normal cables. It matters aesthetically esp as raising sockets higher in a listed property.

[@Mandrag0ras]

In line crimp connectors is my favorite method. The most sturdy and reliable in my opinion.

[@samgriffiths]

I never knew that was acceptable under the regulations. Thanks for educating me.

[@samuelverrinder5847]

Thank you for the advice. So simple.

[@fje1948]

Thank you!

[@Giggler.]

After u fitted the connector you mentioned the cable needs to be doubley insulated? Can you explain what that means please

[@ForidKhan123]

I believe he means heat shrinks. But would’ve been ideal for C&G to demonstrate it to remove any doubts.

[@rayc1503]

Yeah heat shrink

[@paulroberts9704]

Would heat shrink be acceptable for second insulation?

[@davidfraser6613]

I do 🤷🏽‍♂️

[@WarrensRandomAndWeirdVideos]

I’m guessing so yeah

[@rayc1503]

Yup

[@Baggiolyful]

Im conflicted with using butt crimps on solid conductors. They do make a good join if crimped correctly however they’re better suited for stranded conductors. In domestic work it’s probably fine but on ships or aircraft’s for example they could become loose overtime from vibration. Then again these installations probably use stranded cables to allow for movement

Great videos, Wago now do a straight through connector. As you say the side by side ones are a bit bulky. If burying a repaired twin and earth back in wall, is it acceptable to reinstate second layer of insulation with insulation tape? Many thanks, Pete 👍

[@rayc1503]

It's not good practice to do this .However if burying cable in walls you should either make sure it's either accessible for maintenance. meaning you could use a patress back box or a maintenance free junction box. For example ideal/wago/hager with the appropriate type tested joints within the enclosure. Any other form of connections wouldn't be to regs. ideal spliceline inline connectors are spot on for extending cables within consumer units and back boxes. Rated @ upro 32 Amps ideal for radial ring circuits.

Would heat shrink be acceptable?

[@rayc1503]

@@paulroberts9704 If it's just the outer layer and the internal insulation hasn't been damaged then I'd suggest self amalgamating tape for extra assurance. The problem with heat shrink is ,how would you get it on without cutting the cable? Electrical tape's fine if the outer insulated sheath hasn't been damaged too much.

[@paulroberts9704]

Thank you

[@petermikus2363]

There is a single wire straight through however no more sadly.

[@DDGARDENING2024]

Do this method apply to a cooker switch

[@vman2kay]

Would be nice if there was a video showing how to extend the cables/repair outside of a socket (say a drilled cable) as that's not really covered much :(

[@genome616]

I would take caution to learning off youtube videos, the issue been even though a lot of the advice is good he actually is wrong in this video, that crimping tool and crimps are not to be used on solid core cable, they are suitable for stranded cores and thus he has demonstrated a method that can give a very poor joint.

[@Interdiction]

Would you put brown tape on over the blue for idiots thinking it was a neutral

[@jitsmen2519]

Can I use 1.5mm?

[@cag9284]

I would use a 3 way wago

[@neilvincent9530]

In line splice connectors would of been quicker

[@genome616]

Oh the Irony of this guy trying to teach us how to extend cables and then shows us using a crimping tool and crimps not designed to be used on solid core cables, when you have to educate the educator it is a sad day. In this particular instance an indent crimper is preferable and suitable crimp to match, stranded or fine stranded are suitable for the crimp tool and crimps he is showing as the wires easily form into the shape the crimp tool creates, a solid wire does not and often creates a poor crimp where the crimp itself is damaged or not formed properly.

I'm planning extending ebike cables, does it loose electric transfer when extending?
