Extending wires in consumer unit. Discussion ThreadExtending wires in consumer unit. Electrical Advice

Hi, everyone.

I need to move a circuit to an MCB at the other end of a split load board.

The cables all enter the CU at one end, and the cables in question will not reach the breaker at the other end without extending them. It is a ring final circuit.

What's the best method to do it? I was going to use in line crimps with heat shrink over. Would that be OK?

Any advice...
