Snagging on a new build

[Adam_92]

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
