Cable for outdoor lamp too short

Hi,

when stripping the cables, I was probably a bit too thorough. In any case, I now have maybe 0.5 cm of cable coming out of the thermal insulation. How can I extend them or have them extended by an electrician?

Small cable and if necessary insulating tape (where the terminal block might be the better choice) - just make sure no water can get on it and that the power is off when you fiddle with it.

Terminal block does not work because the lamp sits directly on it, i.e. the opening through which the cable passes. Terminal block is too thick

Then strip a small piece of cable on both sides, twist the wires on one side with the cable stub and tape both open connection points well (of course so that the wires cannot touch each other).

Some of the tips here sound very adventurous, even for a layman like me, who, however, has an electrician as a father and therefore has received some basic knowledge. I would advise against repairing cables just by twisting them together; that is by no means professional and will not work here at all. The cable is likely 1.5mm^2, which cannot be twisted to 5mm. Besides, that would be extremely dangerous. Even terminal blocks are no longer state of the art. Electricians today also prefer Wago connectors for fire protection reasons. You should definitely get a professional. However, he will probably also face a problem that is not so easy to fix properly. 5mm is really too little to patch something there. I think a professional will have to pull a new cable if he wants to do it properly. Unless your specification of 0.5 cm is greatly underestimated. That is 5mm, and you can hardly grip the cable there.

Yeah, I'll give the electrician a call.
