Loving these things.

Can the functional earth cable conductor be trimmed down to make it more tidy?
Do you put earth sleeving over the white functional earth conductor?
Do you put the functional earth in the earth block on the same way as the circuit CPC or do you group all functional earths together and put in one earth way on the earth bar?

I have seen some RCBOs with sprial neutral and some without.
I'm assuming that on on either one the neutral cannot be cut down.

Cheers All

Yes.
No cream is the correct colour for functional earth
Yep pop it in the correct circuit no on the earth rail
Trim the N as you see fit!

as above... -----^^^^

i find that a bootlace crimp on the neutral is normally in order as its made up of fine strands that just "fluff" out and can be a pain!!

I'd agree with all of the above.
Just to add that you may need to add a bootlace ferrule to any cut ends, as the strands on both the functional earth and the neutral can be very fine and may not terminate properly without.

Edit: Ahh! Durham's too quick for me.

Thanks All - what are the common sizes of ferrules needed for RCBOs? - do you stick with blue ferrules for N and white for earth?
