Noticed this mains was a bit of a mess, so thought I'd have a tidy up.

what happened to the DP isolator??

There's one in the new CU. What's the point of having two idenitcal switches in series with one another?

now you've got that Schneider beast in there, not a lot.
Impressed with the neutral tails though, they can be a pig in that size board, did you straighten them out or just tuck them all behind the mcb pan curly?

Straightened them out and choped them down a bit. There's a bit of slack at the back of the pan, should they ever need retermination.
All the argument on here and the petition that was started to get all supplies fitted with them!
And they are being removed by electricians!
and cut out and bushed the back of the board for the outgoing cables?
I somewhat agree with Westie, they're useful for a board change, but that Schneider board will be good for 25+ years, if not a lot longer, so in this case, it's pretty redundant
Yes, as an 'observer', it does seem fairly odd to me to have got rid of it!

Unless, of course, the 18th Edition calls for DP RCBOs (or MCBs), most of them remain 2-module width and one wants to 'upgrade to current reg standards'
Kind Regards, John
Not seen that style board before,
Whats going on at the top.
I (Think) I recall from your previous posts an issue with isolators.
I am unsure why this is, would be interested to know why.
I like to be able to work on a board knowing no power is getting to it
I often see a lot of bare copper at the incoming terminals, it makes me very hesitant. Isolated board - lovely.
Oh and the 18th I was told by my assessor is to be RCBO boards - and away with ring final circuits

the top is the 'busbar' the schneider MCB pan contains the busbar, so you can turn ways on and off by sliding the brown switch and a little metal prong (ie busbar prong) slides out into the MCB/RCBO
John, if that is the case, MF's will undoubtedly remanufacture to 1 module width

I thought the metal prong was fixed (as with any other 'comb' busbar, and the switching done internally. I've seen, but never played with these boards, so I could be wrong.
I think if we get DP RCBOs they'll first be fitted to TT installs where isolation requirement is DP, however I think there would be physical limitations to manufacturing 18mm wide DP RCBOs. Hager do a good compromise which is a 36mm DP RCBO with one of the busbar tunnels being blind and a cable coming out the front instead.
Even so, I'm sure if there was any risk of a neutral to earth fault causing dangerous electric shocks even with the line removed then we would have banned SP RCBOs by now. After all they've been in the book a good 20 years.
They used to be badged as Merlin Gerin, at the top are sliders that move down to cover the screw hole and power up the stub that powers the MCB/RCBO.
You lost the 2 red cable ties on meter load phase.
