Extending 16mm2 cable

[Mlb]

What is the best way to extend 16mm2 house wire? Is a ferrule and crimper the way forward or are there other options? I'm having my DB relocated and the cable feeding the DB is about 1m short so I'm hoping one can just extend the existing cable and not replace the entire cable.

A proper crimp, hexagon, with tape and then heatshrink in a joint box will suffice - You not saying what distance is involved in replacing the complete length which would be the fool proof way - Sometimes by the time you finished with labour , boxes etc you may as well have replaced

Will the join be in a junction box or inside the DB?

I need to extend by 1m. The entire run is about 9m x 2. So I'd have have to purchase 18m. Cheaper to extend

In a junction box in the roof space

I would extend using a ferrule. There are other options like a line tap, no crimper required. If it was a temporary connection, I would use a 3M electrical connector.

Lots of different methods but I'd go with a hex crimped ferrule and 2 layers of adhesive heat shrink or maybe DIN rail mounted, straight thru terminal block inside an enclosure depending whether it might ever need to be disconnected in future. I even came across MC4 connectors used to extend wires on an AC circuit a few months ago, it was a neat job but I'm not sure how it sits with the manufacturers instructions.
