Snagging on a new build

[Adam_92]

Bs 61009 are RCBO’s…. I doubt the trip time for each individual RCBO was exactly 33ms for each one.

Can we get a photo of the CU with the lid open showing the breakers?
We might find they’ve taken a blank out to fill in the hole in the top

got home and had a look they’re mcbs 60898

Turned off (kitchen sockets) whole of downstairs went off
Ill have to get my tester out on the weekend and test everything

makes me worry haven’t even scratched the surface

So that schedule is completely wrong they have 61009 instead of 60898. I would be taking this further as this shows total lack of procedures.

I raise this with the contractor or the NICEIC? I’m going to contact the builders about the issue first

If they're going to make up the test results... at least get the BS details to match so its not so obvious.

It's been years since I've fitted a dual RCD board, RCBOs all the way now. I also went to a new build recently and the certificate for the property didn't match the installation at all. Though that was the least of the problems with the wiring.

I’m going to get the builders to arrange another company to do an EICR

I Dont fit Hager boards but is that SPD even wired up? Usually when the SPD sits to the right of the main switch its fed from an MCB, how does the bus bar get from the main switch to the SPD past the neutral terminal on the switch if its fed direct.

Edit: I've just found this picture which explains it,

dont really like that, how thick is the fly-lead and what happens if the SPD shorts live to neutral, that cable will fry before the main fuse goes but I suppose the neutral lead would do the same on other SPD's fed direct from the bus bar. Wouldn't surprise me if SPD's end up causing a whole load more problems than they solve in the coming years.

I’ve not even had the time to remove the board cover at the moment still busy trying to sort out everything else wrong with the build! Will post a picture tonight when I’m home
