20amp RCBO neutral fly wire only 1.5mm

[Micky j]

Why does a 20amp RCBO come with only a 1.5mm neutral flywire when you are driving a 2.5mm power circuit. Aren't you creating a choke, & potential voltage drop. I appreciate it can carry 20amps but it doesn't make sense to me

What make is that RCBO with the 1.5mm lead?

 

[James]

The reason is cost.
if you calculate the volt drop for 100mm of cable it will be negligible.

As above, volt drop for that length is negligible and in a fairly free-air space within the CU (panel) it can carry 20A OK (just!).
