Extending SWA garage cable

[Luka]

Ferrules are used on multi strand conductors prior to termination to protect them.

Thanks, it worked well, but I have a problem. It turns out that the neutral terminal slots are too small for 10mm2 cable (it's an old CU). Can I run 6mm2 instead of 10mm2 from CU to junction box if I feed it from 30A MCB instead if 40A?
