Full rcbo boards????

[D00DY_T00DY]

Hi all,

Probably going to seem like a novice question just wondering what techniques you lot have for full rcbo boards to keep it neat.

Put 5 in today for a temporary supply for ground workers on a genny; earth rod with a Zs of 2.13ohms (fairly good?)

Anyway it was a complete nightmare trying to keep it neat with the earth and neutral flexes out of them.

I've only installed less than 10 just wondering all your techniques for rcbos?

I kept all the length on these and tried to coil them nicely behind the cpc and neutral terminals.

I cable tie them and loop them behind incoming L-N and splay them up to the terminal. Was thinking of ferruling them with shorter cable. The functional earths are crazy though at what .5mm? and also long, it is a bit messy and annoying I have to work with such tat.

Some say there isn't actually a conducter In there at all

I tried connecting all the rcbo flexes out then get them all together then connect my circuits but fighting 6mm wires round was just a pain so I'm thinking circuits first then move the flex round the circuit wires and cable tie them all together.

It'll be a while till I'm installed rcbos again though.

I agree, I did an 8 way Wylex the other day and was doing great with neatness which all went to pot with the functionals and the neutrals. I cable tied across in a group of 2 then splayed.
Good experience though. Was a small dimension board though as it had to fit in a meter box!

Well indeed a spark I know just connects even the functional earth to neutral. It does get me though as the FE is so small and mixing sizes in the same termination is somewhat unreliable.

Just how big was that fish again ?
You've beaten my record (6.x Ohms) that's for sure !

I know Memshield 3 isn't the same quality as Memshield 2 but the rcbos have no earth lead.

Not all RCBO's have earth leads ...

Stick some functional earth coloured sleeving over them cut to length, nice and neat no problems imo

SBS compact RCBO's. you use a double bus bar so no neutral tail or functional/reference earth.

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.

fish???? this is what my lad landed the other day.

I beg to differ. RCBOs are far better than the dual RCD boards with massive tails cluttering up the whole space. I just cut the neutral lead down to size and fit a 4 or 6mm2 boot lace ferrule. These things cost pence. As for the f/earth , take them to below the bus bar, into a wago 222 then take a 2.5mm2 single from wago222 up to earth bar. Also if you are installing C/U as a replacement there is much less chance of nusance tripping.

very neat, mate.

Cut and ferrule

Very nice @hightower think I will go for ferrule now I've seen that. I do however have reservations about ferrules in that it is possible for it to slip out of the ferrule
