Probably an industrial or commercial spark who though it would be easy cause its only a bit of house bashingI wonder if, and again no offence OP, he did a shorter course or something?
I think you'll find they should go into the bottom of the main switch, otherwise it'll still be live when you turn the main switch off ?They should go to the top of the main switch.
Yes I misread the opening post I thought he was referring to the supply conductors.I think you'll find they should go into the bottom of the main switch, otherwise it'll still be live when you turn the main switch off ?
That is a good thing, as you might want to shuffle the loads around, but...A couple of issues. The busbar needs cut. Comes as a 15 way and needs to be 2x 6…
<= this is absolute crap!but as you can see here, the RCDs are physically deeper than the MCBs, so the bus at sits at a slight downhill slant.
This in turn gives all the breakers a slant and it’s near impossible to get the cover back on.
I'm unlikely to be fitting domestic CU but this has been very informative as a reason not to go with ones of these.Secondly, one of the 16A MCBs is faulty, doesn’t click on.
Third. The 35mm knockout for a tails gland is below the RCD. Would have made sense to put it on the right where there’s plenty space.
Just me. I like to push the busbar as far up as I can, thinking the terminal gets the best grip. I suppose I could set it directly horizontal.the reason the busbars slant is if you push them too far into the MCBs. i never had any trouble with BG.
Not a bad design overall the dual RCD boardAs luck would have it, I just fitted a BG board that the customer had supplied.
Populated split RCD board, 10 way (5+5)
You can just about see how the internal connections are made.

Note the ferrules crimped onto the ends of the internal links.

I was moaning about this very morning regarding the location of the 30mm knockout, you have to assume that it’s not designed by sparks ?As luck would have it, I just fitted a BG board that the customer had supplied.

I’d normally agree with you, but he is gaining experience by doing this in his own home.To the OP...get someone in who knows what they are doing....This is a CU your messing around with not a 2 gang switch
