Full rcbo boards????

It is bolted to the left side panel with one end unterminated.

He did say for the lid.

Ah yes didn't read that

The only thing I don't like about RCBO's, is there's no obvious sign as to whether it's the rcd or mcb element that has tripped. I understand most user instructions suggest trying to reset 'once', and sparks flying out of the thing might give the game away, but you'd think the manufactures might of developed some form of visual indicator (someone's gonna tell me there is). Seem to recall the early MK RCBO's tripped to the half way point, if it was the rcd?

Cut and ferrule for me every time.

Like to leave a little bit length still so the RCBO isn't completely useless if it does need to be moved a little in the future.

That looks good with the tails all ferruled, i think I will be doing that myself

Hopefully you always fit ferrules to flex in crew terminals, as otherwise you are not complying with the regulations!

Regs don't require ferrules be fitted.
They require the fine stranded wire be protected against damage from the screw terminals which can be satisfied by twisting and then doubling over the strands.

Think the regulation is every connection shall have adequate mechanical strength and be suitable for the terminal or something along those lines

The requirement is that the conductor ends be suitably treated, which as usual is as clear as mud.
But, twisting and doubling over does not provent the strands from being broken when the screw is tightened, if you undo the screw and take the conductor out you will find a number of broken strands.
Ultrasonic welding and ferrules are the two commonly used methods which actually work.

That is not the regulation i was referring to, see 526.9
