MK RCBO wiring

[Les Desser]

I have lost the instructions that came with the unit.

What is the function of the blue and white wires?

Thanks.

Blue (thick) is the connection to the neutral bar, and white (thin) is the connection to the earth bar, if it's the same as ones I've installed in the past.

Also remember to connect the circuit neutral to the RCBO's neutral connection, and not take it back to the neutral bus bar directly!

Thank you and John.

Obvious really now I think about it, but the white colour threw me. Why is it not green/yellow?

[Alistair Riddell]

Probably because it is a functional earth, and not a safety earth (at least in the normal sense of a circuit protective conductor or equipotential bonding conductor). Cream is the standard colour for functional earth wires.
