Is there a maximum length for a spur cable?

Good afternoon, hope you are all well.

Just two quick questions.

Is there a maximum length for a 2.5mm twin and earth spur cable terminated in a ring final wall socket?

Is there a maximum length for a 2.5mm twin and earth spur cable terminated in the Consumer unit RCBO which also supplies a ring final. I understand that there can only be one spur cable from the RCBO. So max three cables in RCBO.

As always, many thanks in advance.

Hi sorry to be blunt but that’s incorrect, you can have more than one spur from an RCBO, the limitation comes from how many conductors can be confidently and competently connected into any given terminal :)
