RCBO board.

[securespark]

Hard to imagine, I know, but after 20 odd years in the business, I've just done my first all-RCBO board change! (No pix, I'm afraid...)

Well, John, you've sold me short! You didn't tell me what a PITA they are to fit....

Seriously, the boards need a good redesign to make them easier, seeing as this is the way things are going.

How about:

1. Much more headroom for outgoing cables in the boards as the RCBO's rob most of it, especially where you have cables coming in from the rear.

2. A second earth busbar just for the functional earths, so you don't have to put two unequal-sized conductors under one screw.

3. More room for the 600mm long neutral tails (loathe to cut them as they were nicely crimped at the ends).

4. One module DP RCBO's to be developed.

5. Redesign of RCBO to make terminating the circuit neutrals easier. I ended up connecting the circuit neutrals to the RCBO's before attaching them to the DIN rail, but that meant leaving extra length on them, thus reducing the room available in the board even more...

Anyone want to modify or add to this list??

RCBOs aren't all they are cracked up to be are they?

SP not much good for TT anyhow.

I didn't say that....

3.(loathe to cut them as they were nicely crimped at the ends).

Why not invest in a ferrule crimper.
mine does up to 6mm flex.
And does and looks a very professional job

Thank you for telling me what you think I should have wriiten.

It's so nice to know I have a Guardian Angel

Now are you going to tell me that I shouldn't be thinking what I'm thinking?

Don't want to hijack the post, but here's a piccy of my first one that I did recently - replacement of old rewireable box.

Agree with all your points, especially no 2 - the functional earth leads are so much thinner that I could see them slipping out easily if not very carefully checked every time.

I did cut the neutral tails because of room, but it did seem a shame I agree. Maybe ferrules are the way to go (will a normal crimper not do those?)

What brand did you use? I used Wylex because my supplier was doing a good deal on them - 21.99 + vat each, so it didn't work out much worse than a dual rcd board, and I extolled the virtues to the customer (John would be proud )

I notice that B&Q have MK rcbos in at not much more though (and cheaper than my supplier could do) so perhaps I will check those out next time.

I've also experimented with some BS 8436 cable on another job extending a lighting circuit, but that was just as much a PITA to be honest....
