I discovered a problem with a join in a ring main and decided to

this needs to be rated at 30A to correspond with the fuse (RCBO) or if
15A would be okay on the basis that it is a ring and some of the
current will go each way round.

On the Brunel principle I am fitting 30A but I am curious to know.

The video shows that the connectors will carry the current when new.
But what happens after they have had a few thermal cycles?
I would think the wire nut and the choc block will fail first.
